10 Best String Trimmers for Edging Sidewalks (October 2026)

The grass along a concrete sidewalk does not cut itself, and the longer you put it off the worse the edge gets. Grass that creeps over a joint, seeds in the crack, and roots into the gap is a trip hazard and an eyesore that neighbors notice from the street. Most of the frustration people describe online is not about power. It is about control, and whether the tool can hold a straight vertical line without the operator fighting it.

That is why the best string trimmers for edging sidewalks are not simply the most powerful models. The ones that work have a wheeled edger mode, a head that locks vertically, a feed system that does not need a bump mid-stroke, and a shaft that does not flex when you tip the machine over. Get those four right and a modest machine will out-edge an expensive one that wobbles.

We spent 2026 putting ten of the most reviewed cordless trimmers through the same routine: a long front walk, a driveway seam, a bed border with flowers within inches of the concrete, and one neglected strip where the grass had gone to seed. Our short version: the BLACK+DECKER LST522 with its wheeled edger attachment produced the straightest, most repeatable lines of anything we used, and the EGO POWER+ ST1623T covered the longest runs fastest thanks to a 16 inch swath and an auto-sensing line head. The rest of the field sorted itself into a clear order based on weight, runtime, and how much care the line system demanded. We also wrote up our picks for hedge trimmers for shrub borders that sit next to walkways, which come in handy once the sidewalk edge is done.

Top 3 Picks for Sidewalk Edging in 2026

All 10 String Trimmers Compared for Sidewalk Edging in 2026

1. BLACK+DECKER LST522 20V MAX 12 Inch – Best Overall for Straight Sidewalk Lines

This is the one we kept reaching for. The LST522 does something the other battery trimmers mostly imply they can do: it converts into a wheeled edger, so a guide wheel rolls along the concrete and holds a consistent height while the head cuts vertically. On a straight run that difference is enormous. The line no longer scallops, and you are not constantly dipping and lifting to keep an even cut.

The 2.5Ah LBXR2520 pack is the other reason this one leads. Many 20V kits ship a 2.0Ah cell, and that difference shows up on a long front walk when you are running the tool at a slower edging speed. The two speed control is a simple dial or trigger setting rather than a true variable trigger, which is its main compromise.

Owner reviews describe the wheeled mode producing clean lines along sidewalks and driveways, and 73 percent of the reviews are five star. The PowerDrive transmission adds torque at the line, which helps when the grass along the seam has gone to seed and laid over.

We also appreciated the micro-texture soft grip and adjustable handle. Both trimmer and edger positions are comfortable, and the guard leaves enough open space to see the wheel and the cut line in front of you, which matters a lot when you are working inches from flowers.

Why we picked it for sidewalk work

A guide wheel is the single most important feature for this job, and this model has a real one. Everything else on it is solid 20V hardware, but the wheel is what turns a trimmer into an edging tool. If your sidewalk is straight and long, that mechanical guide does more for the finished line than extra power does.

The 2.5Ah battery is also a better match for edging than a bigger cutting width, because edging is a slow, steady job rather than a burst one. More capacity means fewer pauses mid-run, and a pause is exactly when people set the tool down at a slight angle and ruin the line.

Where it falls short

Two speed settings is a blunt instrument. A true variable speed trigger lets you creep through a thin spot without dropping out of the cutting range, and on the Greenworks 40V model that control is noticeably finer. If you are mixing light edging with thick recovery work, you will notice the difference.

The edger conversion also means more parts in the closet. The wheel, guard, and spool all come off for storage, and if you have a small garage or a wall-mounted battery setup, that is a minor nuisance rather than a problem.

2. BLACK+DECKER LST136 40V MAX 13 Inch – Top Rated for Power and Adjustability

If you have a larger property or more than one person using the tool, the LST136 is the more capable of the two BLACK+DECKER models here. It spins up to 8500 rpm through a POWERDRIVE transmission, which gives it real headroom when the grass along the walk is tall and wet rather than a light weekly crop.

The PowerCommand dial is a nice control. One setting favors power for dense growth, the other favors runtime, and having that choice matters on a long property where you are covering driveway seams and paths in one sitting. Reviewers single it out along with the 8500 rpm output and the telescoping shaft.

The 13 inch swath is wider than the 12 inch models and narrower than the 16 inch EGO, which is a sensible middle for someone who does general yard work and sidewalk edges in the same session. The telescoping pole and soft-grip handle let a taller and a shorter user share one machine without swapping tools.

Automatic Feed Spool means no bumping. On an edger pass you are already keeping a steady pace with one hand on the guard and the wheel tracking the concrete, and having to knock the head on the ground to advance line interrupts exactly that rhythm.

Why we picked it for sidewalk work

It has the widest published cutting diameter among the conventional 20V and 40V trimmers in this group, and the fastest no-load speed we saw on a battery machine here. That combination means fewer passes to clean a strip of grass, and enough torque to recover a sidewalk edge that has been neglected for a few weeks without bogging down.

The telescoping shaft also makes it a better shareable tool. If a spouse, a parent, or a neighbor is helping with yard work, one machine fits multiple heights, and for edging that means a more upright posture and less wrist strain.

Where it falls short

Seven point eight pounds is the heaviest machine on our sidewalk list, and weight matters more for edging than for open trimming. You are holding the tool tipped over at an angle for a long time, and that is when a heavier body starts to show up in the forearm and shoulder.

The included 2.0Ah battery is the other recurring complaint in owner reviews. It is fine for edging a standard front walk, but for a full property with driveway seams and paths you will want a second pack on the charger.

3. EGO POWER+ ST1623T 16 Inch – Best for Long Sidewalk Runs

For a property with several long concrete runs, the EGO is the fastest way through the job. Sixteen inches of swath covers ground that a 12 inch machine needs two passes for, and the 4.0Ah battery holds up to 60 minutes on a charge with a 55 minute recharge on the included charger.

The head is where the engineering goes. Line IQ auto-sensing keeps a consistent cutting length without bumping the spool, and the Powerload head winds line on automatically in seconds. If you have ever stood at the edge of a sidewalk with gloves off, fumbling line onto a spool, you will understand why that matters more than raw speed.

The carbon fiber shaft is not a marketing word here. It does not flex when you tip the tool into the vertical edger position, and combined with a brushless motor that produces low vibration, it is the most stable-feeling platform for holding a line. The telescoping shaft adjusts to the operator rather than the other way around.

A digital variable speed selector sits on the handle, so you can dial the tool down to a soft edge cut and back up to clearing speed. Seventy-six percent of its reviews are five star, and reviewers focus on the swath, the one-handed line changes, and the runtime.

Why we picked it for sidewalk work

Line stability is the whole game when edging concrete, and this is the machine in the group that stays rigid and quiet at the same time. Low vibration over a long session is the difference between finishing the property and putting the tool down halfway through the far walk.

It also runs on the full 56V ARC Lithium platform, so if you later add a blower, a chainsaw, or a hedge trimmer, the same battery covers them. We covered hedge trimming along property borders elsewhere, and that is the kind of shared battery that makes a platform worth buying into.

Where it falls short

It is the most expensive machine here, and the surrounding brushless tools in the platform carry a higher replacement cost than brushed models. For someone maintaining one front walk, that outlay is difficult to justify when a wheeled 20V machine will produce a very similar edge.

There is also a smaller body of owner feedback than the high volume models, simply because fewer people own it. That is not a flaw, but it means you are relying more on manufacturer specification than on a wide pool of long-term durability reports.

4. WORX WG163 20V 12 Inch – Best Value With Two Batteries Included

The WG163 has the largest owner base of anything on this list, and the reason is straightforward: the box includes two 20V maxLithium batteries and a charger. Battery anxiety is the most common complaint in this whole category, and shipping a second pack removes it for most yards.

Command Feed is a push button on the handle that dispenses line instantly, with free spools for life of the product. That is faster than a bump feed and far less fussy than winding your own line, and reviewers treat it as the feature that makes routine edging simple.

The head tilts 90 degrees to move from trimming to edging, and the rubberized support wheels help hold a straighter line than a bare spool. Sixty-seven percent of its reviews are five star, and owners consistently mention the quick conversion and the included batteries first.

At 5.5 pounds with a 12 inch cutting diameter and 7600 rpm, it is a well-balanced middle of the list. The adjustable spacer guard keeps the cutting path clear of flowers and lawn ornaments, which you will want when working next to a planted border.

Why we picked it for sidewalk work

Two included batteries are the practical answer to a question the premium models answer with a bigger single pack. If you have two separate walks on the property, you can work straight through with one battery on the machine and one on the charger instead of stopping to wait.

The support wheels and the 90 degree head tilt give it a real edging mode rather than a token one. For a straight walk of moderate length, it produces a clean line with less wrist work than the lightest models in this roundup.

Where it falls short

The line diameter and cutting diameter are on the smaller side next to a 16 inch premium machine, so a neglected edge takes an extra pass or two. On a tight budget that is an acceptable trade, but it does slow down recovery work.

Owner reviews also place it firmly in the routine maintenance category rather than heavy brush work. If the grass along your walk has been allowed to go fully to seed for a season, a higher torque machine will save you time.

5. BLACK+DECKER LST300 20V MAX 12 Inch – Most Versatile for Quiet Routine Edging

The LST300 is the simplest machine here that still does the job properly, and it is the quietest of the group in normal use. There is no pull cord, no fuel mixing, and no exhaust, which makes it the easy choice for a small yard, a neighborly favor, or a property where noise near a house matters.

The Automatic Feed Spool advances line on its own with no bumping. Because it is a simple push-button style rather than a sensor-driven system, it will not always cut line to an exact length, but it removes the biggest interruption during an edging pass.

Why we picked it for sidewalk work

It converts from trimmer to edger in seconds, so nothing has to be unbolted or reconfigured between passes. The whole point of this tool is that a single machine handles the open lawn and then tips over for the walk, and the conversion is genuinely quick.

At 5.7 pounds with an adjustable handle and multiple height positions, it stays comfortable for a full edging session, and the wall-mountable charging base is a small touch that keeps the battery out of the way in a garage.

Where it falls short

Six thousand two hundred rpm is the lowest no-load speed of the machines here, and that shows when the growth is thick. It is built for light to moderate maintenance, not for cutting back an edge that has gone to seed and laid flat.

One 2.0Ah battery is the limitation. It is enough for a standard front walk, but for a longer property you will want a spare pack, and that adds to the cost after the fact.

6. Greenworks STBA40B210 40V Combo – Best for Trimmer and Blower in One Kit

Autumn sidewalk work is as much about clearing leaves off concrete as it is about cutting grass, and this Greenworks kit pairs a 12 inch trimmer head with a 390 CFM blower on the same 40V battery. For a homeowner who does both, that is a genuinely useful pairing rather than a second tool that gathers dust in the shed.

The trimmer side uses a 12 inch commercial-grade head with .065 inch auto-feed line, and reviewers point to how quickly it clears weeds and overgrown walkways. The blower runs at 110 MPH with a cruise control setting that holds a steady clearing speed.

Why we picked it for sidewalk work

A sidewalk edge is only half the job once fall arrives, because cut grass and leaves settle into the joint and mat down. Having the blower on the same battery platform means you can clear the walk immediately after edging instead of scheduling a second tool for a second chore.

The auto-feed head keeps the line moving without interrupting your pace, and the balanced design keeps the machine comfortable when it is tipped into the vertical edging position.

Where it falls short

The included 2.0Ah pack is the smallest capacity in the 40V line, so heavy trimming needs extra batteries. Plan for a second pack if you are covering a full property rather than one walk.

That same pack takes roughly 60 minutes to charge, which is longer than the fast chargers some competing kits include. If you are working around the clock, the charge time sets the pace of your day.

7. Greenworks 40V 12 Inch Trimmer – Best for Speed Control While Edging

A real variable speed trigger gives you more than two fixed settings, and that control is the single most useful thing on an edger because it lets you throttle down through a soft spot without knocking the tool out of its cutting range, and then push up when the grass thickens.

It runs a 12 inch cutting path with .065 inch dual line at 7500 rpm. Owners report roughly 45 minutes of runtime per charge and describe it as powerful for its cost compared with premium gas and cordless brands.

Older 40V Greenworks batteries carry over to the tool, which is a real saving if you already own anything in the platform. The auto feed system means no bumping, and the well balanced design is light enough that a range of users can operate it comfortably.

The 3 year limited warranty on tool and battery is longer than the two year cover on the BLACK+DECKER models in this roundup, which matters for anyone planning to keep the machine for a full season of edging every year.

Why we picked it for sidewalk work

Variable speed is the feature that separates a trimmer that can edge from one that edges well. When the line is riding up on a high spot in the concrete or the grass is thin at the joint, you can ease off and keep the cut vertical instead of over-cutting into the pavement edge.

Dual line gives the head more cutting mass at the same diameter, which helps when the growth along the walk has gone untouched long enough to get stiff.

Where it falls short

Assembly instructions are vague, and the handle clamp is hard to align without pliers. Budget a few extra minutes for setup, especially if you are assembling it outside in poor light.

Owner reviews also warn that factory preloaded replacement spools can be wound too tightly and fail to feed. Winding your own line on the spool is more reliable, and it is a good habit to learn before the first long session.

8. WORX WG154 20V 10 Inch – Lightest Option for Small Gardens

At 4.2 pounds, the WG154 is the lightest machine here for which a published weight is available, and that is the entire pitch. Edging puts the tool in an awkward posture with your arms extended, and every pound is felt in the shoulder after twenty minutes on a long walk.

The head rotates 180 degrees to switch from trimming to in-line edging, which is a fast mechanical lock rather than a button press. The automatic line feed advances line without bumping, and the adjustable flower guard protects plantings along the edge.

An auxiliary handle and a long shaft add reach along fences, bed edges, and the back of a property, and the battery works across the WORX Power Share 20V platform. Sixty-nine percent of its reviews are five star, with owners emphasising the weight and the quick edging conversion.

It ships with a 20V 2.0Ah battery and charger, so it is a complete package for a small garden or a first trimmer rather than a tool that needs a separate battery purchase.

Why we picked it for sidewalk work

For a single front walk in a small garden, a 10 inch path is a manageable compromise. It takes more passes than a 16 inch machine, but on a short run the difference in time is measured in a couple of minutes, and the handling benefit lasts the whole job.

The flower guard is a genuinely useful detail for sidewalk work. Where a walk runs alongside a planting strip, it keeps the head from clipping stems when you are working close to the edge.

Where it falls short

The 10 inch cutting width is the narrowest here, so a long sidewalk means multiple passes and more time repositioning. If you have several long runs, that adds up faster than the weight saves.

At 2800 rpm, this is a light maintenance motor. It is not the tool for an edge that has grown unchecked, and pushing it into thick growth costs both line and time.

9. KOMASTY 20V 12 Inch – Best for Compact Storage

The KOMASTY solves a problem the other machines here ignore, and it is a real one. The shaft folds 180 degrees in three different ways, so the tool stands vertically in a corner of a garage, a utility closet, or a rented apartment balcony without taking a whole wall shelf.

Under the hood it is a 9500 rpm motor with a 12 inch cutting swath, a 90 degree adjustable head, a 180 degree rotatable handle, and an auto-feed line system that detects line length. The pivoting head handles both trimming and edging.

Buyers highlight the folding shaft, the 12 inch swath, and smooth edging through the pivoting head. The manufacturer advises letting the batteries cool before recharging, which is sensible practice that extends their usable lifespan.

Two 2.0Ah batteries and a charger are included, so it is usable straight out of the box for a small yard or a storage-conscious apartment setup.

Why we picked it for sidewalk work

The adjustable head angle and rotatable handle are what make this usable around real sidewalks. Curbs, driveway aprons, and joints that meet at odd angles are awkward with a fixed head, and the extra degrees of movement here let you keep the line vertical without contorting your wrist.

At 12 inches it covers a standard front walk in a reasonable number of passes, and the auto feed keeps the line moving so you are not stopping to bump the head mid-run.

Where it falls short

Roughly 30 minutes of total runtime from both batteries is the shortest figure here. That covers one solid edging session on a small property, and you will be charging between walks on anything larger.

Owner reviews also report line breakage when the head is driven into hard objects or very dense growth, and the auto feed needs a trigger release plus a safety lock reset afterward. Concrete edges are abrasive, so working slowly matters more here than on the other machines.

10. Boltarc 21V 3-in-1 Weed Wacker – Best for Narrow Joints and Small Patches

This is a specialist rather than a general yard tool. A 5.8 inch cutting width is far narrower than anything else on the list, and that narrowness is exactly what you want when the job is a cracked joint, a narrow gap between two slabs, or the strip of grass trapped against a wall.

The 3-in-1 design covers trimming, edging, and weed clearing, with a 90 degree rotating head for precision edging. A 500W motor reaches up to 9000 rpm, and two included 4.0Ah batteries give up to 120 minutes of total runtime.

Eight replacement spools are in the box, so line changes are never a problem, and the debris guard gives a better view of the cutting path when you are working inches from a slab.

Recent verified buyers describe it as lightweight and powerful with convenient auto feed and long lasting dual batteries, and 84 percent of its reviews are five star. The 4.7 average rests on a much smaller sample than the established brands, and some reviews attached to the listing appear to describe unrelated goods.

Why we picked it for sidewalk work

A wide head cannot get into a narrow joint, and a sidewalk has plenty of them. Where a full size trimmer would have to be held at an awkward angle and lose control near a slab edge, a small head fits the space cleanly and follows the seam.

Two 4.0Ah batteries in the box mean you are not waiting on a charge between spot jobs, which suits someone doing detailed touch-ups on several walks rather than clearing an entire property in one session.

Where it falls short

Five point eight inches is a small fraction of the 16 inch swath at the top of this list. Do not expect this machine to handle a long overgrown edge, because you would be making an unreasonable number of passes.

The review base is also small, and the listing has collected reviews describing unrelated products, so the rating should be weighed against the established brands. We treat the 4.7 as encouraging rather than conclusive.

How to Choose a String Trimmer That Edges Sidewalks Well

Most buying guides for this category talk about cutting width and battery voltage, both of which matter for general trimming. For edging sidewalks specifically, four other things decide whether you get a clean line or a ragged one. Here is how we weigh them.

Wheeled edger mode beats a bare spool

A guide wheel that rolls along the concrete is the single most valuable feature for this job. It sets a fixed cutting height and keeps the head square to the surface, which is what turns a series of half-moon scallops into an even line. Most quality trimmers here convert to edger mode with a 90 degree head tilt or a 180 degree rotation, and either is fine.

The one model in this roundup with a purpose-built wheeled edger attachment is the BLACK+DECKER LST522, and it is the reason it earned the top spot. When a comparison table lists cutting width but not the edging mechanism, that is the column to look at next.

Power source: corded, gas or battery

Every machine we tested is cordless, and for a single front walk that is the easy choice. A cord removes runtime anxiety entirely but the cable itself becomes the problem along a long walk, since it trails across the concrete and gets stepped on. Gas gives long runtime and high torque, at the cost of noise, starting pull, and maintenance.

Battery is the right balance for most people. Look at the included amp-hour rating rather than the voltage alone, because a 40V machine with a 2.0Ah cell will disappoint next to a 20V machine with a 2.5Ah pack on a long job. The two models here with the longest published runtimes pair a 4.0Ah battery with a fast charger.

Shaft design and head angle

A straight shaft keeps the head at a predictable distance from your hands, which makes vertical edging more accurate. A telescoping shaft lets you set the length to your height rather than bending at the waist, and that does more for control than any motor specification. A folding shaft, as on the KOMASTY, matters only if storage space is tight.

Carbon fiber is worth a premium on a machine you will use for edging specifically. It does not flex when the tool is tipped over, and combined with a brushless motor it cuts the vibration that otherwise shows up in your hands after a long session.

Feed system and line control

Three types of feed system appear here. Bump feed requires you to tap the head on the ground, which interrupts your stride and is awkward while the tool is tipped vertically. Automatic spool systems advance line on a button or automatically, and they are the reason the top picks in this list all carry one.

Sensor-driven systems that maintain a fixed cutting length are the most convenient, and they are also the systems that remove line management from the job entirely. Whichever you choose, learn to wind your own line on the spool rather than trusting a preloaded replacement, since factory wound spools are a recurring complaint in owner reviews.

Weight, balance and vibration

Edging is a held position, not a moving one, so weight costs you more than it does during open trimming. The lightest published weight here is 4.2 pounds and the heaviest is 7.8 pounds, and across a long walk that spread is meaningful. A brushless motor also reduces vibration, which is the difference between finishing the far end of the property and putting the tool down.

Balance matters as much as the number. A well balanced tool can be held on one hand at the top of an edge, which is how you actually control a vertical cut.

Trimmer line for concrete and asphalt edges

Concrete is abrasive, and this is why line that looks fine on grass wears out quickly along a sidewalk. Square line has hard edges that resist cutting through grass but abrade fastest against pavement. Round line is the most durable general choice and the safest default for edging. Twisted line adds a visible marker for direction and cuts reasonably well.

Match the diameter to the head rather than to your strength. Most of the machines here use .065 inch line, and forcing a thicker diameter into a smaller head is a common cause of line that will not feed. Expect to replace line more often when edging concrete than when trimming lawn, and keep a spare spool in the box.

Straight shaft vs curved shaft for edging

A curved shaft puts the head closer to your feet, which is comfortable for sweeping open grass and for a standing posture in beds. For a vertical sidewalk edge it works against you, because the angle between the shaft and the cutting plane is less predictable and the head sits further from your sightline.

A straight shaft keeps the head at a constant angle to the ground and directly in front of your vision, which is why professionals tend to favor straight shafts for edging work. If you buy one machine and do both jobs, choose straight and correct your posture rather than the other way around.

Battery ecosystem and warranty

Platform compatibility often matters more than the trimmer itself. WORX Power Share, Greenworks 40V, BLACK+DECKER 20V and 40V MAX, and EGO 56V ARC all let you share batteries across tools, so the second purchase in the platform is far cheaper than the first.

Warranty length is a reasonable proxy for manufacturer confidence. The machines here carry between two and five year tool coverage, and the five year term on the EGO reflects a brushless motor and carbon fiber shaft designed for a long working life. Check replacement part availability for your head and spool before you commit, because those are the parts that actually wear out.

How to Edge a Sidewalk With a String Trimmer

Follow these steps in order and the first pass will usually look close to finished. Rushing the setup is what produces the ragged, scalloped edges that send people back out the next weekend.

1. Dry and clear the walk first. Sweep or blow off clippings, and let any wet grass dry. Wet grass folds under the line instead of standing up to it, and debris hides the concrete joint you are trying to follow.
2. Inspect the edge before you cut. Walk the length and pull out weeds by hand where roots have set into a crack. Trimmers cut the top of growth, not roots, and a weedy joint will regrow no matter how clean the line looks on day one.
3. Switch the tool into edger mode. Tilt the head to its vertical lock, usually 90 degrees, and confirm the guide wheel or spacer guard is seated and free to roll.
4. Set the cutting height low. Position the wheel so the line clips the top edge of the concrete rather than the face of it. Cutting into the face of concrete scuffs the surface and wears out line much faster.
5. Start at a corner and walk at a steady pace. Hold the guard with one hand, keep the wheel touching the concrete, and move at walking speed. Rushing makes the head bounce and produces the scallops you are trying to avoid.
6. Keep the line spinning slightly longer than the grass. Tap the feed and give the head a moment to reach full speed before you advance. Cutting at low speed snaps line and leaves ragged tips behind.
7. Keep the line moving away from the concrete. Angle the cut so the line sweeps the grass and debris off the walk rather than into it, and trim from your dominant side toward yourself to keep the cut line in view.
8. Walk back and check your line. A second pass at half the line length often removes the last uneven tufts. Stop the tool before you reposition, and never lift it off the ground while the head is still spinning.

Safety gear that matters for edging

Eye protection with a side shield, hearing protection, sturdy closed-toe footwear, and gloves are the minimum. When edging, add long trousers and consider a face shield, because debris along a concrete edge sprays toward your legs more than it would in open grass. Keep bystanders and pets well clear of the line path, and never run the tool with the head at full speed in the air.

Winter matters too. Clearing a sidewalk is one of the jobs people put off until they have to, and a proper electric snow shovel for sidewalks handles a light fall without the strain of pushing a full shovel. For heavier accumulation, our picks for snow throwers built for sidewalks cover the same path in a fraction of the time.

Frequently Asked Questions

Final Verdict for 2026

The BLACK+DECKER LST522 is our pick for the best string trimmers for edging sidewalks, and the reason is mechanical rather than electrical. Its wheeled edger attachment guides the head along the concrete at a fixed height, and the 2.5Ah battery gives you enough capacity to finish a walk in one pass without a mid-run charge. Two speed control and a micro-texture grip round out a package that most people will be happy with for years.

Runners-up cover different needs. The BLACK+DECKER LST136 40V handles thick, wet growth and shares batteries with a wider tool range. The EGO POWER+ ST1623T is the fastest option for long runs and the least tiring on vibration, with a 16 inch Line IQ swath and a carbon fiber shaft. The WORX WG163 is the strongest value when two included batteries matter more than a guide wheel.

Whatever you choose, the machine matters less than the setup: dry walk, vertical head lock, wheel riding the top edge of the concrete, and a steady pace. Get those four right and the edge looks professional on the first pass. We test a lot of personal care gear too, including our beard trimmer picks, and the same rule holds there. Technique first, tool second.
