Big bad slicer!
Ryan K. on Jul 13, 2021

This knife is big and intimidating, as far as folders go. It opens with ferocity and confidence. The AT-X lock is pretty cool, although I kind of wish the slider and thumb studs were made of metal instead of plastic.Other than that, the texture under the pocket clip is super rough, meaning it's gonna tear up my pants quickly. Also, the pocket clip is a major ergonomic blunder. It digs into my hand severely. I get the feeling this thing was made for people with bigger hands. It's not very practical, but it's a fun knife. It makes people gasp when you deploy it, and it's really badass. I might pass it on to someone who gets more of a kick out of it than I do.

Too much for what it is
Ross I. on Feb 3, 2022

I had issues with needing lots of pressure on the studs to get this knife to deploy. After a ton of actuations it's smoother finally and deploys well. It's the small details that put me off on this one; plastic hardware and thumb studs that either catch or do not place pressure evenly, pressure against the back skull crusher into your hand on deployment, and unfortunately now side to side play on the blade. I put moderate (not hard) pressure against the side of the blade with my thumb and the knife has opened up slightly and that play is now in the action. It's a great looking knife, incredibly sharp, and assisted action is bad-ass..
