Ruko Knives Socius Features The Ruko Knives Socius folder is built around a 3.25 inch 440C stainless steel blade finished in black oxide combining high hardness with a low-glare corrosion-resistant coating. Rated to a hardness of 59 to 61 the blade holds a sharp edge through repeated use and resists dulling better than softer steels. The partially serrated edge pairs smooth push-cutting performance with the ability to saw through tougher fibrous materials when the task calls for it. A smooth ball bearing pivot system keeps the blade s action fast and fluid opening cleanly with the assistance of a thumb stud. The handle is built from aluminum and rubber for a secure all-weather grip that stands up to repeated use in the field or around camp. A low profile reversible pocket clip allows comfortable carry on either side of the body and the ambidextrous design including the flipper guard suits both right and left hand users. At 8.5 inches overall and 6.56 ounces the Socius strikes a balance between a substantial blade and a knife that still carries comfortably in the pocket. Secured by a dependable liner lock the Ruko Knives Socius folder is available for sale at GrabAGun.
