ABSTRACT

Any one who has attempted to repoint a hypodermic needle knows the difficulties encountered. The illustration shows a simple and effective device for sharpening them.

The length of the bevel can be varied by thrusting the needle through the cork at different angles.

A similar method may be used to sharpen scissors. A gash should be made across the flat surface of the cork, and the incision should be slanted into the cork, and made deep enough so that a blade of the scissors, when pressed into the slit, will find its level parallel with but not quite to the surface of the cork. When drawn across the stone, the edge should touch the grinding surface sufficiently to be sharpened.
