This VORTEK knife called the FULLTILT is quite possibly the best designed knife I've ever owned. It is simple, sleek, sturdy, stylish, and sharp AF! The generous four inch blade deploys lightning fast with its ice slick ball bearing, safely stays open with its unyielding liner lock, and snaps closed with a very positive detent. The finger flick opener that turns into a quasi-quillion is an amazing feature too, there's no blade stud to get in the way of cutting or breaking off to make the knife less than tactical when the going get tough. The G10 scales are smooth yet grippy; I'm very happy with this purchase, no pun intended (actually it is). I was after a super high quality defensive knife and certainly got what I wanted! Right now I'm considering the Kyoto and Warthog. Now every silver lining has a cloud, would VORTEK please make a few of these excellent designs in a five inch or longer blade? That'd be awesome. Great job guys!
