Cold Steel Oyabun Features The Cold Steel Oyabun features a 3.5 inch 4034 stainless steel blade that has been expertly heat treated and given a high satin polish resulting in a sharp edge that holds up under regular use. The blade s reinforced point improves durability during piercing or prying tasks without sacrificing the fine geometry needed for everyday cutting. An integral flipper lets the user deploy the blade quickly with one hand and the leaf spring lock engages to hold the blade securely open during use. At a 57 Rockwell hardness the steel strikes a balance between edge retention and ease of sharpening. The handle combines a Griv-Ex foundation with a soft checkered Kray-Ex over mold for a secure non slip grip in a variety of conditions. Stainless steel liners reinforce the handle adding strength without significantly increasing the knife s 4.10 ounce weight. Two robust bolts fasten the over molded grip to the frame ensuring long term durability through repeated use. A pocket clip allows for convenient secure carry making the Oyabun a practical everyday companion for work or outdoor tasks.
