Hand stamps are stamps made from high-quality tool steel with which single digits or letters can be engraved on different materials e.g. steel, iron or aluminium using a hammer.
The generally elongated stamps with a square cross-section have characters on one side which are to be engraved in a raised and sharp design. The impact head on the opposite side is either thermally untreated or it is hardened and tempered. Hand stamps are usually delivered in sets, exclusively with digits or with letters.
