3. While sharpening, the temperature of the piece must not exceed 120º, given that to the contrary, cracks will
appear and will subsequently cause the blade to break. The steel must never reach a bluish, dun-yellow colour.
4. After sharpening, the blades must be polished, first with 180-grain sand paper and then with 320-grain paper.
