ABSTRACT:
A sharpener apparatus includes a base, a linear bearing assembly mounted on the base, and a support block carried by the bearing assembly for reciprocating movement along a rectilinear path relative to the base. A planar abrasive surface underlies the support block which has one or more open channels for receiving workpieces in sliding relation with the longitudinal axes of the workpiece preferably inclined to the abrasive surface. A pusher member is supported by the support block adjacent each channel for applying a constant force longitudinally of the corresponding workpiece to urge its tip against the abrasive surface. Manual or powered reciprocating movement of the support block effects an abrasive action of the workpiece tips against the abrasive surface to form a highly accurate and repeatable tip geometry, such as a chisel point, on each workpiece.
