The teardrop-shaped thumbhole and angled thumb ring on this super gator shears set your hand in a natural position. Because the thumb is not overextended during scissoring, the tension on the hand and wrist is greatly reduced and scissoring is accomplished with less effort. Calibrated "click-plate" tension dial allows you to customize the tension of the shear. The tension dial clicks your settings into place with each turn, so tension will not loosen during scissoring. The stainless steel sponge-iron used in super gator shears is triple-tempered for ultra pureness, creating a metal density that provides supreme balance with a rockwell hardness rating of 59 for an amazingly durable blade edge. Optional ring inserts, included with each shear, create a better fit and reduce rubbing and blistering. Shears measures 7-1/2-inch length.
