What Matters Most for This Category
In this category, the details that matter most are whether the tool offers true 2-in-1 trimming and edging, whether a battery and charger are included or sold separately, the cutting width and line feed system, and whether you already own tools on the same battery platform. Auto-feed spools and steel cutting decks, like on the BLACK+DECKER LST300, reduce ongoing maintenance, while shared battery platforms (such as WORX 20V Power Share) let one battery cover multiple tools.

Who Should Avoid the Top Pick
Buyers with large, overgrown, or heavily wooded properties, or anyone needing a true walk-behind edger for deep, continuous edging along long driveways, should look beyond this group of handheld 20V cordless trimmers. These tools are built for routine residential upkeep, not for clearing thick brush or replacing a dedicated gas-powered edger.
Before You Buy
Before buying, check whether the battery and charger are included in the listing or sold separately, confirm the line diameter and spool type if you already own a compatible trimmer, and match the cutting width and deck material to how often and how hard you plan to use the tool. If you already own cordless tools from WORX or BLACK+DECKER, checking battery platform compatibility can save money over buying a standalone kit.
FAQs
Which string trimmers & edgers are best for lawn edger?
The WORX WG163 and BLACK+DECKER LST300 are built specifically as 2-in-1 trimmer and edger combos with a dedicated edging mode, making them the strongest picks if edging along walkways and driveways is the main priority.
Which string trimmers & edgers are best for trimmer edger combo?
The HEYWORK, WORX WG163, EWORK, and BLACK+DECKER LST300 all offer 2-in-1 trimmer and edger combo functionality, letting one tool switch between cutting grass and defining lawn edges.
Which string trimmers & edgers are best for walk behind edger?
None of these seven products are true walk-behind edgers; they are all handheld cordless string trimmer and edger combos, so anyone who specifically needs a walk-behind edger for long, continuous edging should look at dedicated walk-behind models instead.
Which string trimmers & edgers are best for battery string trimmer?
All seven products run on 20V battery platforms, making them battery string trimmers; the HEYWORK, WORX WG163, EWORK, and BLACK+DECKER LST300 are standalone trimmers, while the generic 20V kit includes its own battery and charger and the WORX WG928 pairs a battery trimmer with a leaf blower.
How do I choose string trimmers & edgers?
Start by deciding if you need a basic trimmer, a 2-in-1 trimmer and edger combo, or a multi-tool kit, then check cutting width, whether a battery and charger are included, the line feed type, and whether the battery platform matches any cordless tools you already own.
Our verdict
All seven options are cordless 20V tools aimed at routine residential trimming and edging rather than heavy-duty lawn care. The HEYWORK and WORX WG163 lead for general 2-in-1 use, the BLACK+DECKER LST300 stands out for its auto-feed and steel deck, and the replacement line pack is worth keeping on hand for existing Black+Decker owners.
