Normal Hall Marking:
Produces a raised description with a sunken field when
applied to a work piece.
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
Used for marking general flat items such as tags, giftware,
salvers and ingots.
