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.

Abstract: A new and unique construction for a corn cob cutter knife is presented. A method is described for the manufacture of a unique cutting blade insert which is tapered and which has an inner ski angle compatible with the many applications involved in removing corn kernels from a corn cob in a mechanized operation. The unique removable cutting blade insert is designed so that the various angles of declination and attack optimize the sharpness and long lasting nature of the knife. A method is also presented to determine the off-set grinding radius for the ski angle of the knife. A unique square bushing for the control of the knife is also provided.
