Ruko Knives Shark Features The Ruko Knives Shark uses a spring steel liner opening system referred to as S.R.D.S. to deliver fast reliable one handed blade deployment whenever the knife is needed in a hurry. The blade is machined from 420 stainless steel and finished in black oxide a coating that both reduces glare and adds a measure of corrosion resistance beyond what the bare steel alone provides. A partially serrated edge gives the user a plain section for controlled precise cuts along with a serrated section capable of tackling tougher materials like rope or seatbelt webbing. An electroplated locking liner secures the blade open during use adding confidence that the blade will stay locked through demanding cutting tasks. The handle combines black anodized aluminum with rubber overlays producing a secure non slip grip that holds up even when hands are wet or sweaty. An ambidextrous thumb stud lets either left or right handed users open the blade with equal ease broadening the knife s appeal to a wide range of carriers. At a closed length of 4.50 and a weight of 5.44 oz the Shark is compact enough for daily pocket carry while still offering a full size usable blade when opened. The knife includes a pocket clip for secure carry and a window punch for emergency use and it is available for sale at GrabAGun as a practical ready for anything folding knife.
