Most shears in the listings use stainless steel or carbon steel blades. A few cordless tools are described more generally as having durable metal blades.
Many hand shears use a bypass action for clean, plant‑friendly snips. Some motorized tools use dual‑action or double‑slice blades that cut twice for a smoother finish.
Listings mention corrosion‑resistant stainless steel and rust/corrosion‑resistant coatings on carbon steel blades to help preserve edge life and durability.
2‑in‑1 tools typically switch modes with a one‑click or quick‑change mechanism that lets you swap attachments or blade assemblies quickly between hedge‑trimming and grass‑shearing configurations.
Some multi‑tool shears include multiple blades; for example, a configuration may pair a 4" grass‑shear blade with an 8" shrub blade.
