Design Stamp - Fire Department Patch 6mm
All of our design stamps (punches) are made from heat-treated tool grade steel. To work successfully with design stamps and punches, place the metal you want to stamp on a hardened steel bench block. The bench block must be on a firm flat surface. Do not use a sand bag or any other padding below. The bench block needs to rest directly on a flat hard surface. Hold the punch perfectly straight. Use a 16 oz utility hammer to hit the end of the stamp. Ideally the impression should be made with one blow. Practice with copper until you can get a good impression with one blow.
