CobraTec Knives CTK-1 Features The CobraTec CTK-1 uses a kinetic locking system with dual action deployment so the 2.75 inch D2 steel dagger blade fires and retracts with a single push or pull of the control switch. The blade carries a polished finish and a Rockwell hardness of 61 giving it solid edge retention for everyday cutting tasks. At just 0.5 oz and 7 inches overall when open the knife tucks easily into a pocket without adding noticeable bulk. The zinc aluminum alloy handle is finished in Tiffany Blue giving the CTK-1 a distinctive look among everyday carry OTF knives. The reversible pocket clip allows the knife to be carried tip-down on either side of the handle accommodating right or left hand preference. A built-in glass breaker adds emergency utility for vehicle escape situations and the included nylon sheath provides an alternative carry method. Backed by CobraTec s Lifetime Warranty the CTK-1 is a dependable compact choice for daily carry.
