This alloy allows the blade to be honed to razor sharpness. Blades stay sharp for months. Shears are precision weighted and balanced. Handles and finger rests are contoured for maximum comfort. Double screw tension produces smooth scissoring. These features combine for a shear that drastically reduces the amount of effort needed for scissoring. The result is an increase in productivity and a reduction in hand fatigue. Hardness rating of 57. Made of stainless steel and measures 10-inch length.
