Impact punch steel

The impressing stamps (height 6.5 cm, edge length 7 mm; type height 4 mm) are made by a German manufacturer, who has been producing embossing tools since 1932; they have a Rockwell-hardness of 58 to 60 HRC. They are produced, first, through a pressing method and then flame hardened; in this way, they are suitable – technically formulated – for impressing into workpieces with up to 800 N/sq m firmness. This value describes their possibilities and limitations. You would hardly be able to impress the head of a serious hammer; however, you could easily inscribe a shovel, a snow sweeper, and the majority of metal sheets – and, naturally, wooden handles as well.

In two variations:
26 capital letters as well as the &-symbol.
9 digits from 0 to 9 (with the 6 in a double role).
