Ergonomic micro-finish handles have a patented non-slip surface that will not peel, crack or deteriorate. These handles are made from cellulose-acetate, which is impact resistant, cadmium free, and dense enough to eliminate the risk of sharp objects becoming embedded in it. Oil and moisture flow away from the handle surface for a powerful, non-slip grip. Even with oily or wet hands you get the maximum force and comfort. Chrome-plated vanadium-molybdenum, hardened and tempered tool steel blades for exceptional life, wear resistance and high torque performance. Blade tips are precision ground for exact fit.
