Kershaw's Cyclones feature an innovative "On/Off Option" that lets you control when to use the SpeedSafe assisted opening system and when to use fully manual operation. Simply flip the roll-switch on the knife's spine to choose manual opening or to engage the Cyclone's ambidextrous SpeedSafe system. The high-performance blade is Sandvik 13C26 stainless steel for durability and edge retention. Handsome, anodized-aluminum handles provide lightweight strength and make the new Cyclones ideal for pocket carrying
