The Knockout looks great, but the reason it bears this name is that we've "knocked out" a piece of the lightweight aluminum handle and inset a stainless-steel plate to create a frame lock that we'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. It's equipped with our new deep-carry clip and is drilled for quad-carry: tip-up, tip-down, left- or right-handed. Made in the USA. 3" blade. 7-7/8" Overall.
