The C.U.M.A. Protector Knife is far from those cheap knives you buy at the store. Designed in conjunction with DayOne Gear, this knife was specifically made with Police and Fire personnel in mind. This bad boy features a glass breaker, seatbelt cutter and a functional edge to assist with weapon retention. Designed by Waysun Johnny Tsai, this knife has a 1095 high carbon steel blade that has been black powder coated and heat treated to 56-58 Rockwell. That's one thick, solid piece of metal that will never break. Comes with a black Kydex sheath.
