PROBLEM TO BE SOLVED: To easily cope with the abrasion of a blade face of a knife without delay, by cutting a number of almost parallel slots at desired intervals along a surface of a hard plate. SOLUTION: A face bar on a surface of which a number of almost parallel slots 5 are cut at random, is bent into the U-shape, and is molded and machined to a work bench 1. When a knife is ground, the work bench 1 is taken out to be fit to one of left and right side edge parts of a chopping board 2, and tightly fixed by bonding a Hook and Loop fastener face. A suitable amount of the fluidized abrasive is extruded from a tube onto an upper face of the work bench 1, and roughly spread by a finger. Further the abrasive is flattened by a cutter from an upper part, to bury the abrasives into the slots 5. Then the blade face is moved foward and backward along the slots 5 of the upper face 4 to be ground. On this occasion, the water is unnecessary, so that the sharpening can be performed in safety with a comfortable position at any stable, wide and bright place having the height suitable for the work, such as on the table or the like. |
