Choosing a lawn edger string trimmer is mostly a question of matching the tool to your yard.

The seven models below were selected on published specifications, brand reputation and common patterns in owner feedback. Our criteria were battery platform and runtime, cutting width, weight and balance, line-feed convenience, and whether the head converts easily between trimming and edging.

Buying Guide
Cutting width and head design
Most models in this category use a 10- to 14-inch cutting path. Wider heads cover ground faster, while narrower heads reach into tight corners. Check whether the head converts between trimming and edging with a simple adjustment or requires tools.
Good picks for this: PowerShare WORX WG163 2-in-1, 12″ Electric String Trimmer & Lawn Edger
Battery platform and runtime
Two-battery packs let you keep working while one charges. Capacity in amp-hours (Ah) indicates runtime: a 4Ah pack lasts roughly twice as long as a 2.0Ah pack under similar load. Check whether batteries share with other tools you already own.
Good picks for this: 2*4Ah Battery Powered 2 in 1 Lawn Edger, 12 Inch Lightweight Trimmer & Edger
Corded versus cordless operation
Corded models have unlimited runtime but need an outlet and extension cord. Cordless models offer freedom to move around the yard but depend on battery charge. Choose based on where your outlets are and how much area you cover.
Good picks for this: BLACK+DECKER BESTA510 Weed Wacker, BLACK+DECKER LST300
Weight and balance
A lighter tool reduces wrist and arm fatigue during edging. Look for balanced weight distribution and a comfortable shaft. Heavier battery packs add weight, so weigh the runtime benefit against comfort.
Good picks for this: PowerShare WORX WG154 10″ 2-in-1, 12 Inch Lightweight Trimmer & Edger
Automatic line feed
Auto feed releases more cutting line when you tap the head on the ground, saving the trouble of stopping to reload. This matters most for frequent trimmers. Check spool capacity and whether replacement line is easy to find.
Good picks for this: BLACK+DECKER LST300, 12″ Electric String Trimmer & Lawn Edger
Durability and deck material
A steel deck resists damage from rocks and debris better than plastic. Shaft and gear housing quality also affects long-term reliability. Look for solid construction in the areas that take the most abuse.
Good picks for this: BLACK+DECKER LST300 20V MAX, PowerShare WORX WG163 2-in-1
Care and maintenance
Clean the head after each use, replace worn line, and keep batteries charged between seasons. Store batteries at moderate temperatures. Follow the manufacturer’s manual for the exact maintenance schedule and warranty terms.

FAQ
Can a string trimmer really edge a lawn?
Yes, when the head rotates to a vertical position it can cut a shallow edge along hard surfaces. A dedicated edger usually produces a cleaner, deeper line, but a 2-in-1 model handles light edging well.
How often do I need to replace the trimmer line?
Replace line when it becomes short or brittle. Frequent use on edges may wear line faster. Keep spare spool line on hand so you can finish a job without interruption.
What battery size should I choose?
For small yards, a 2.0Ah battery is usually enough. For larger lawns or longer sessions, a 4Ah pack reduces the need to swap batteries mid-job. Two batteries let you keep working while one charges.
Is a corded model better than cordless?
Corded models provide consistent power without charging, but they limit your range. Cordless models are more flexible for moving around the yard. Pick based on your outlet access and yard size.
Do I need eye and ear protection when using these tools?
Yes. Flying debris and noise are common hazards with trimmers and edgers. The manufacturer’s manual usually recommends eye protection and hearing protection. If you have questions about safe operation, consult the product manual or a qualified professional.
How do I avoid damaging my lawn edges while trimming?
Keep the head at a shallow angle, work slowly along the edge, and avoid pressing into soil. Make several light passes rather than one deep cut. See our related guide for technique details.
Conclusion
For most homeowners, the PowerShare WORX WG163 2-in-1 offers a balanced mix of runtime, convenience and edging performance. Owners of small yards or tight spaces may prefer the lighter 10-inch or 12-inch models, while those with larger lots should consider the 4Ah battery option. Budget-minded buyers can look to the BLACK+DECKER LST300. Match the cutting width, battery capacity and weight to your yard, and you will get clean lines without overspending on features you will not use.
