ABSTRACT:
A knife sharpening device includes a vertically-oriented base having a vertically-oriented slot. Mounted on the base, on one side of the slot are two crossed sharpening members of a rod-like configuration. A lower end of each of the crossed sharpening members is anchored in a horizontally-extending pivot pin with a terminal end of each of the sharpening members extending beyond the pivot pins and engaging a horizontally-extending stop pin. The pivot pins are rotatably mounted in the base and extend through the base. A pivot wheel is mounted concentrically on a free end of the pivot pins on an opposite side of the base from the sharpening members. Two radially-extending set screws extend through the pivot wheels and engage a flat surface of the pivot pin to hold the pivot wheels on the pivot pins. Extending between the two set screws, threadingly mounted in the two pivot wheels, is a tensioning spring. The two ends of the spring are wrapped around the set screws and encased in a heat-shrunk polyolefin wrapper to secure the ends of the tension spring to the set screws.
