Another excellent quality budget knife! The Zenoid is spring assisted; Give the blade a push via the thumb-stud and the knife does the rest (you can also press the flipper on the back of the knife). The blade opens consistently and locks up solid. The silver aluminum handle has G-10 scales (front and back). The 440 stainless blade is satin finished (partially serrated) and features a rescue hook. The Zenoid has a pocket clip mounted on the back (tip down).
