The other important matter in a screwdriver is that the point be of the right temper, so as neither to bend nor to break.

If the corners break they can be reground, but care should be taken not to make the angle too obtuse or the driver will slip out of the slot in the screw-head.

The bevel should have a long taper.

A shop should be equipped with different sizes of screwdrivers to fit the different sizes of screws.

Screwdrivers vary in size, the shank ranging in length from 2-1/2" to 18".
