The Greenworks 40V 8 inch edger is our pick for most yards: it has the biggest blade and the highest voltage here, an 8 inch blade on 40V with a 4.0 Ah battery, the deepest listed cut at 2.25 inches, a brushless motor and a 3 year tool and battery warranty. The WORX WG898 has the lightest published tool-only weight here, 7.06 pounds, with a brushless motor and three depth settings.

A lawn edger cuts a clean line where grass meets a sidewalk, driveway or garden bed, which a string trimmer cannot match for a sharp border. We compared three cordless stick edgers from Greenworks, WORX and BLACK+DECKER, each sold as a kit with a battery and a vertical steel blade.
How We Chose
We picked three well-known lawn tool brands and matched the type: each is a cordless walk-behind stick edger sold with a battery. They are not identical: the Greenworks runs on 40V while the WORX and BLACK+DECKER run on 20V, blades range from 7 to 8 inches, the batteries range from 1.5 to 4.0 Ah, and the brands state run time in minutes or in feet of edging, so we do not rank them on run time. Weights are for the tool without its battery where the brand gives that figure. Specs come from each manufacturer’s own product pages and manuals, and each card lists the warranty from the brand’s own pages. Prices are the Amazon prices on the date shown.

Frequently Asked Questions
Is a lawn edger better than a string trimmer for edging?
For a sharp border along concrete, yes. An edger like these runs a vertical steel blade guided by wheels, so it cuts a straight, clean line, while a string trimmer turned on its side tends to wander and leave a softer edge.
How deep do these edgers cut?
Greenworks lists up to 2.25 inches for its 40V 8 inch edger, WORX lists 1.5 to 2 inches across three settings for the WG898, and BLACK+DECKER lists a 1.75 inch cut capacity for the BCED400C1.
Do these edgers come with a battery?
Yes. Greenworks includes a 4.0 Ah battery and a charger, WORX includes a 4.0 Ah battery and a 60 minute quick charger, and BLACK+DECKER includes a 1.5 Ah battery with the BCED400C1 kit.
How long does a charge last?
Greenworks lists up to 60 minutes with its 4.0 Ah battery. WORX lists up to 2,800 feet of edging per charge and BLACK+DECKER lists up to 815 feet, so the figures are not on the same basis.
What warranty do they have?
Greenworks lists 3 years on the tool and battery, and WORX lists 3 years with product registration. BLACK+DECKER’s product page does not state a term for the BCED400C1, so check its warranty page.
