ABSTRACT:
A needle sharp conical point can be quickly honed by methods and apparatus that employ reciprocating or rotating abrasive surfaces that may be revolved in a circle around the point being sharpened. A reciprocating surface may be used to hone non-conical points. The size and shape of the points may be adjusted by changing the location at which the moving abrasive surface intersects the axis of the point. Examples of hand held, portable , self energizing apparatus are disclosed.
