The Whirlwind is a classic Kershaw SpeedSafe assisted-opening knife. The slight trailing-point blade is Sandvik 14C28N stainless steel, a high performance steel designed by Sandvik in collaboration with Kershaw. The design offers solid piercing capabilities combined with enough belly for slashing tasks, plus enough straight cutting edge for a wide range of day-to-day knife duties. The handle is comfortably shaped to fit the hand and built of sturdy injection-molded Polyimide. Closed, the knife is 4.5 inches. A pocket clip is included and the knife is also available in a partially serrated version as model 1560ST.
