The REAPR TAC Bowie's 7" blade is 4mm thick, crafted from 3Cr13 stainless steel with a black oxide finish. It is extremely durable, easy to sharpen and the tactical oxide finish reduces reflection and prevents rust. The "Bowie" style knife was made famous by "Rambo" and "Crocodile Dundee", this Bowie Knife has a very sharp, large grooved blade with a heavy serrated back edge with an overall knife length of just over 13". The 6" TRP (thermoplastic rubber) handle ensures slip resistance, even when used with wet or slimy hands. This tough and durable Bowie knife is great for hacking brush, peeling wood for tinder, dressing game, whittling branches and prepping food. When not in use we provide a black hard plastic sheath with a nylon belt loop and fastening strap, and quiet locking system. Overall, considering the price, a GREAT deal.
