I place the spoon on the plate. I place the centre punch on the spot. I hit the centre punch with a hammer. I do this with all spoons.
Medium
Place the spoon on the steel plate. Place the centre punch on the marked point at 1.5 cm. Hit the centre punch with the hammer.
Heavy
The centre punch is now placed on the pre-drawn marking. Use the locksmith's hammer to strike the centre punch with medium force. The steel plate is needed as a base for the spoon to support it.
