ABSTRACT:
This invention relates to a knife sharpener and more particularly to a knife sharpening device wherein the knife is clamped in a fixed position on a table or platform and the knife sharpening or grinding device is moved along the edge of the knife to be sharpened. The knife sharpening or grinding device is clamped into an adjustable arm which is attached to a roller. The roller slides along a track formed in the table or platform which has the identical configuration as the knife blade. Therefore, the edge of the sharpener or grinding device is maintained in constant contact with the edge of the knife during the sharpening. This prevents the problem of knives being sharpened unevenly and inaccurately, as is often seen in conventional knife sharpening methods.
