It's a Knockout in more ways than one. The Knockout looks great, but the reason it bears this name is that Kershaw® "knocked out" a piece of the aluminum handle and inset a stainless-steel plate to create a frame lock that they're calling a Sub-Frame Lock. You get the lightweight benefits of anodized aluminum handles and the strength of a steel frame lock with integral lockbar stabilization.
