ABSTRACT:
Apparatus for providing a sharpened edge on an elongated cutting tool comprising a base member having an elongated slot therein and a pair of elongated sharpening elements each pivotally mounted on the base member at opposite sides of the upper end portion of the slot and extending in crossed relation and intersecting at the slot as a cutting tool is drawn downwardly and outwardly through the slot. Separate counterweights are connected to the upper end portions of each of the sharpening elements to resist their downward pivoting movement as the cutting tool is so drawn through the slot. Separate eccentrically mounted cams are disposed between each cutting tool and its axis of pivot to adjustably control the extent of swinging movement of each of the sharpening elements in both directions. Each sharpening element extends downwardly from its axis of pivot and is curved upwardly, and has terminal portions which are relatively straight and extend slightly therebeyond and downwardly relative to its more curved portion. A third sharpening element is pivotally mounted outwardly of the pair and on the same axis of pivot as the innermost sharpening element, extends in the same general direction, and has a counterweight which is similar but of lesser mass.
