*by O***N on July 29, 2025*

Excellent knife, stays on my tool belt

### ⭐⭐⭐⭐⭐ Works as a Hori knife
*by P***D on October 10, 2025*

Got this as a less expensive and more durable alternative to the trendy Hori Hori knives used in gardening. Use for cutting turf, slicing roots, weeding, splitting perennial clumps, planting bulbs, cutting ties and wire and other garden tasks. Works great in that application. Whenever I go out into the garden I have this strapped on.
