For years Cold Steel has thought about making a folding knife that closely emulates our famous Tanto. The result is the beautiful Oyabun from Cold Steel! It incorporates a reinforced blade point, a high satin polish, expert heat treatment (Rc57 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 our 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.
