Ruko Shark 3.5" Assisted Opening Folding Knife

Ruko's Shark folder uses a spring loaded liner: start the 3.5 inch stainless blade off the ambidextrous thumb stud and the spring carries it the rest of the way open, where a locking liner catches it. That is a one hand job, which is the whole point of an assisted knife when the other hand is holding a rope, a strap or a package.

The handle is rubberized black anodized aluminum, so the knife stays light without feeling like thin plastic, and a pocket clip keeps it riding where you can find it. The stainless blade comes back on a basic stone without a fight. A good candidate for a coat pocket, a tackle box or a glovebox.
