Abstract
A hand-held sharpener tool for a knife or similar implement comprises a unitary body having first and second end sections and a third mid section, processing elements such as sharpening, deburring or whetting elements mounted in the first and second sections. The third section is located between the processing elements of the first and second end sections and comprises an elongated handle on an upper side of the body, and an elongated blade guide and hand guard extending inwardly of the processing elements, the handle and the hand guard forming an elongated ring rearward of the processing elements with sufficient space for a user's fingers to extend between the handle and the hand guard, and the blade guide depending from the hand guard. The processing elements can be provided to sharpen/deburr either a two-sided blade such as a knife blade or a one-sided blade such as a scissors blade. One of the sets of processing elements can be provided as whetting elements to whet a sharpened blade. A fish hook whetstone can be applied to the outer surface of the blade guide.
