The Kershaw Ken Onion Leek is one of the sleekest spring assisted knives around. This model features a composite blade with a blend of 13C26 Sandvik and CPM-D2 Steels, leaving a two-toned blade with a copper accent, simply striking. Bead blasted 410 stainless steel framelock handle. The Leek features Kershaw's patented SpeedSafe technology. Give the ambidextrous thumb-stud a push and the knife takes over opening the blade the rest of the way. This is an ideal one-handed opener. Other features include frame lock design, reversible stainless pocket clip, and a tip safety lock so the blade won't fire by accident.
