The Cold Steel SRK, or Survival Rescue Knife (brand part no. CS49LCK), is a 6-inch fixed blade built for the demands of military and tactical law enforcement work. It’s the standard-issue knife used in Navy SEAL BUD/S, or Basic Underwater Demolition training, a pedigree that speaks to its reliability in genuinely punishing environments. The clip point blade is SK-5 steel finished in a matte black Tuff-Ex coating, giving it a durable, low-glare surface that resists corrosion. A 4.75-inch Kray-Ex handle rounds out a knife proven, again and again, in demanding field conditions.
