The Onion Chive remains one of the most popular assisted knives ever made. The bead blast finished 420HC stainless blade comes razor sharp (partially serrated). Between the bead blast finished handles is Kershaw's patented Speed Safe 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: Framelock, reversible stainless pocket clip, and a safety so the blade won't fire by accident. Perfect size for dress pants, a purse or anywhere!
