My New Favorite Boxcutter
Greg E. on Jun 14, 2018

We just legalized auto carry here in Colorado last August. I don't know how much good a sub-2" blade would do you in a fight, but if you want to have the coolest box opener at work this is your ticket. I think the Aqua color Hogue uses is great, and helps the knife look a little more work-appropriate. The parts are all very well-fitted, and the safety switch isn't loose and flimsy-feeling like on some cheaper autos. The skeletonized backspacer is one of those cool details you don't notice right away. If you're looking for a small auto knife, this one does not disappoint. I'd say it's even superior to a ProTech Runt.

Cool ca legal switchblade.

Not very intimidating, but very cool for edc purposes. After receiving this and playing with it, I noticed that the pivot became loose. I used blue loctite, and tightened it so that it is as tight as possible with the slightest bit of tension on the blade. Cpm 154 is better than normal 154-cm. Coolest bottle opener on the market.
