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.
