Hand forged from a genuine Big Red 13mm box-end wrench, this compact utility knife is built one at a time in the Colonial Metalworks shop. The original wrench is cut, forged, heat treated, quenched, and hand sharpened into a functional blade while preserving its unmistakable tool-room character.

Our wrench knives are intentionally made to look like something a mechanic forged out of necessity at the shop bench, not a polished display piece, but a practical tool with authentic craftsmanship behind it. It's the kind of knife that looks like it has a story before it's ever used.

Whether you're a mechanic, fabricator, tradesperson, or collector of unique handmade tools, this knife makes a memorable gift and an even better conversation piece. Leave it on a desk, workbench, or toolbox and it's almost guaranteed to spark questions.
