An everyday carry with a twist. This sleek, tactically-inspired folding knife is a Ken Onion thought experiment realized: what would it look like to put a rectangular knife handle in a vise grip and twist? In classic Onion form, the result is a surprisingly ergonomic and supremely useful everyday carry blade.

Ken Onion infamously pushes the limits of knife design with every new creation that’s released from his Kaneohe, HI shop. The Helical™ is no exception. With a hardworking satin-finished stainless steel tanto blade, it’s quick to dig into an unopened box. An understated flipper doesn’t get in the way when you slip it into a pocket, but it quickly deploys the blade—when open, a locking liner secures it in place. 

The twisted handles are the showstopper, carefully designed to fit snugly in your palm and outlast any mud, sweat, and grime it encounters. 

The Helical™ is a twisted take on an old classic.
