How to use: - You should place your blanks to a solid flat surface (an anvil, e.g.) - Then put the stamp perpendicular to the blank and make a strong, accurate blow with a heavy hammer. - If you don't have enough power to make it, ask someone else to do it or use a press. Specifications: - A length of stamps' steel rod: from 60 mm to 120 mm (it depends on the size of a logo). - The stamps' steel is hardened (hardness is 54-58 HRC). - Our steel rods have a special cross-hatching for comfortable holding when stamping. Stamps have a special mark for design orientation. - That is a high-quality product made in Europe (stamps have high-resolution, high-quality and precision of lines).
