A string head can’t touch thick weeds, brambles, or saplings — that’s a job for a steel blade attachment. These six cordless trimmers and brush-cutter systems either ship with a switchable blade head or accept one as an add-on, for yard work a basic strimmer simply can’t handle.

Buying tips
- Confirm the blade attachment is rated for woody brush and saplings, not just tall grass, before buying if that’s the job you need it for.
- Attachment-system trimmers (RYOBI Expand-It, EGO Multi-Head, Greenworks) cost more upfront but let one battery power head run trimmer, blade, edger, and more.
- Steel blades need occasional resharpening or replacement — check whether a model’s blade is user-replaceable before buying.
- Battery voltage alone doesn’t determine cutting power — check the actual blade diameter and manufacturer’s stated brush-clearing capacity.
