Ruko Knives Shark Features The RUKO Knives Shark gets its name from its lightning quick spring steel liner opening system which allows rapid one handed blade deployment through the thumb slide mechanism. The 3.25 inch blade is made from 440A stainless steel with an oxide finish giving it a durable low glare surface well suited to daily carry. An ambidextrous thumb stud offers a second method of opening giving the user flexibility regardless of which hand is drawing the knife. The electroplated locking liner design holds the blade securely open during use and releases cleanly when it is time to fold. The handle is built from rubberized black anodized aluminum combining a lightweight aluminum frame with a non slip rubber overlay for a secure grip even in wet conditions. A low profile pocket clip keeps the knife riding close to the pocket for discreet comfortable carry and a seat belt cutter window punch adds emergency utility beyond everyday cutting tasks. Closed the knife measures 4.5 inches making it compact enough to carry daily without adding bulk. Packaged in a clamshell for retail the Ruko Shark suits anyone who wants a fast deploying folder with built in emergency tools.
