The Kershaw Ken Onion Leek is one of the sleekest spring assisted knives around. This knife is chromium nitride coated for hardness and corrosion resistance. The modified Tanto blade is S30V stainless steel and the framelock handle is 410 stainless steel. 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.
