ABSTRACT:
A cob cutter blade honing device which hones the convex and concave sides of a cob cutter blade in a single process is provided. A cob cutter blade to be sharpened is placed into a mounting bracket found at the top of a vertical spindle. Manipulation of an operator control means causes a vertical shaft to engage the hole of the cob cutter blade, aligning it against a locator surface. A locking mechanism then locks the blade into position. Further manipulation of the operator control means rotates the spindle from the alignment and locking position into the honing position. Once in this position, further manipulation of the operator control means causes a movement of the spindle about its vertical axis. As the spindle rotates, a grinding belt engages the convex surface of the cob cutter blade thereby sharpening it and cutting an appropriate toe-to-heel angle. Further rotation of the spindle moves the blade into position in front of a honing stone. The honing stone engages the concave side of the cob cutter blade's creating a beveled edge along the blade cutting tip.
