CobraTec Knives Large FS-3 Features The CobraTec Knives Large FS-3 uses a kinetic locking system paired with dual action operation so a single switch both fires and retracts the drop point blade. The 3.5 D2 steel blade carries a plain edge and a polished finish giving it strong edge retention and resistance to corrosion. At a blade thickness of 0.13 and an overall length of 9 the knife strikes a balance between a compact folding tool and a full size fixed blade. A 61 Rockwell hardness rating on the blade steel means it holds an edge through repeated use without becoming brittle. The zinc aluminum alloy handle keeps the Large FS-3 lightweight at just 0.8 oz while still providing a durable grip for everyday carry. A reversible pocket clip lets the knife ride tip down on either side making it equally usable for right handed and left handed carry. A built in glass breaker adds a practical emergency tool to the knife s primary cutting function and the included nylon sheath gives an alternate carry option beyond the pocket clip. Backed by CobraTec s lifetime warranty the Large FS-3 is built to be a long term everyday carry companion.
