Ruko Knives Shark Features The Ruko Knives Shark opens through a flipper guard mechanism riding on a ball bearing pivot giving the blade smooth fast repeatable deployment every time it is drawn. The 4-inch blade is ground from 420A steel and finished with a mirror polish which gives it a bright traditional stiletto appearance along with reasonable corrosion resistance for daily carry. A plain edge runs the full length of the blade keeping the cutting geometry simple and easy to maintain with routine sharpening. At a measured hardness of 48 to 50 the steel strikes a practical balance between edge retention and ease of resharpening for everyday users. The 5-inch Pakkawood handle is mated to a stainless steel frame giving the knife a traditional look along with the strength to stand up to repeated use. A liner lock secures the blade open during cutting tasks while the closed length of 5 inches keeps the knife compact enough to disappear into a pocket. The reverse low rise pocket clip positions the knife for a discreet low profile carry that rides close to the body. At 5.76 ounces the Ruko Knives Shark is light enough for daily carry yet substantial enough to feel secure in hand making it a solid choice for everyday utility and traditional stiletto fans alike.
