The Cold Steel Sword Cane features an extra strong partial crook handle made from heavy duty nylon and a 2mm thick aluminum shaft that's heat-treated for strength. The tapered shaft is capped with a thick rubber ferrule for better traction on slick, icy sidewalks or uneven terrain. The concealed blade is released by quickly pulling on the handle to break the suction of its friction lock. Made from Stainless Steel with a proprietary heat treatment and tempering, its a hard and resilient blade that's sturdy enough for both cutting and thrusting.
