I have been given a quantity of small punches and I am wondering what they are for. I tried punching steel but it did not leave much of a mark. They work well on aluminium. Are they for hallmarking precious metals?
We used them in school metalwork lessons to decorate ornamental copperwork – serviette rings, ash trays and the like. That was in 1961 when schools had metalwork shops and could afford to buy metal…
