All gravers have makings from the manufacturer which indicates the size and metal quality. HSS gravers always have a yellow paint mark on the tang of the graver; this identifies the mounting point for the handle. Additionally measure the width of the graver and compare with the graver chart below, to determine the size.
Graver handles come in different shapes and sizes, it is advisable to replace the handle with the graver to ensure optimum grip between handle and graver.
Preparing a graver:
A graver tool has to be of a certain length to suit the hand of the user. Held in working position, the end of the tool should project half to three-quarters of an inch beyond the thumb.
A graver, when brought, will be too long and will have to be shortened. If only a small reduction is required a small piece can be broken off the tang before the handle is fitted. The tang is not as hard as the rest of the tool and the broken end should be filed or grinded to a point so that it can be easily inserted into the handle.
If a graver has to be shortened considerably, the end will have to be ground off by using a double bench grinder (code B33154) and care must be taken not to over-heat the tool and “draw the temper” – that is, cause to become too soft for use as a cutting graver. During grinding the graver will become very hot, intermittently dip the graver into water to ensure the steel doesn’t overheat and become brittle. Continue this process until the shape forms a point ready to fit into a handle. One can also use a sharpening stone to shape gravers according to individual specification.
