Incisive Hall Marking :
Produces a “V” groove impression in the material marked, but requires less pressure to apply the mark, thereby facilitating the marking of fragile or thin material that is not suitable for normal hallmarking

Straight Punches :
Used for marking general flat items such as tags, giftware, salvers and ingots.

Cranked Punches (Swan Neck) :
Used in the marking of small items in constricted areas, these punches incorporate formed bodies, hence the expression "swan necked".
