Cold Steel Oyabun Leaf Spring Knife

For years Cold Steel has thought about making a folding knife that closely emulates their famous Tanto. Andrew Demko worked on the problem, and with Lynn Thompson's input, a satisfactory solution was discovered. The result is what we have here, the Oyabun! It incorporates a reinforced blade point, a high satin polish, expert heat treatment (57HRC and sub-zero quenched), and the kind of stunningly sharp edge Cold Steel's reputation was founded upon. Furthermore, it is equipped with an integral flipper for effortless opening, and a (patent pending) leaf spring lock and safety. The lock/safety on the Oyabun was first utilized in Cold Steel's Crawford 1 folder and has proved to be quite tough and reliable. The 4034 stainless steel blade is housed in a strong, economical handle that's reinforced with stainless steel liners. The handle is injection molded with a Griv-Ex foundation and then over-molded with soft, checkered Kray-Ex fastened to the frame with two robust bolts.
