Customer Reviews

Box Cutter Replacement
Kyle M. on Mar 8, 2020

Need to carry a box knife 24/7? Yes, the caliper has little clearance. Definitely for a keyring only but at least that tightness means it won't fall off. Yes, the blade flick is tight, but I don't need to impress anyone by flicking it out. The box doesn't care. The liner lock has a pressure-retaining bead so the lockout & closure both have positive clicks so you know it won't jimmy open in your pocket. Works for me.

Look for another key chain knife
Wendell H. on Jan 6, 2018

I like the silhouette and concept. But the knife is stiff. The calipers (red clip) is difficult to open and has very small clearance. It is difficult to clip on a key ring, belt loop, etc.
