This is our 10″ EXTREME HARD CURVE, this shear is for the experienced groomer. The curve to this shear is unlike any other we have seen, with a curve at 33 degrees. This shear is a heavy duty shear, and is not a light shear by any stretch (4.1 oz), but makes up for it in its well balanced design. This shear has a ball bearing assembly, which you will notice by its smooth cutting action.
