US 7,803,038 B2 · Knife maintenance apparatus

Abstract

A knife maintenance apparatus has a substantially rectangular hone body, a length with an open end and a base end, a width, a top surface covered with an abrasive material, and a bottom surface. There is a first hone edge extending along the length of the hone body and has a first radius. The opposite edge has a second radius and is parallel to and approximately the length of the first hone edge. The first hone edge and the second hone edge are approximately the hone body width apart. There is also a rectangular base portion that has a base top surface, a base bottom surface, a base width approximate the width of the hone body. The base portion has a sliding portion adjacent to and parallel to the base top surface. The base portion is hingably attached to the hone body along the base end and has at least one adjustment hole disposed through both the base portion and the sliding portion. There is at least one adjustment pin that extends through the adjustment hole. There is an adjustment arm hingably attached at one end to the open end of the hone body and hingably attached at a second end to the sliding portion. There is at least one knife maintenance tool removeably fixed on the adjustment arm. When the knife sharpening apparatus is in a closed position, the hone body, the base portion, and the sliding portion are substantially parallel. When the hone body is opened, the sliding portion slides along and parallel to the base top surface and can be latched in position by placing the adjustment pin through one of the adjustment holes to lock the hone body at an angle appropriate for sharpening a knife.
