This shear has a rotating crane handle, molybdenum alloy steel, our Click Lock™ leaf spring tension system and a smooth cutting convex edge. Now we have added Polymer Glide™ lining in the pivots for a super smooth action, eliminating metal-to-metal wear. We have also added sealed ball bearings to the tension system to further increase blade stability and improve the feel. The rotating handle allows you to cut at any angle, with your elbow down. The handle also keeps your hand in an open neutral position. It's no surprise it has always been a best seller.
