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 G-10 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. The Knockout also features SpeedSafe assisted opening. It’s equipped with a deep-carry clip and is drilled for quad-carry: tip-up, tip-down, left- or right-handed.
