Abstract:

A cutting tool such as garden shears, secateurs, toppers, scissors, tin snips, cutting pliers, and the like that employs a circular disc with a sharp, beveled edge. During the cutting process, the disc engages with an opposing jaw. Furthermore, in the cutting process, the disc is forced to rotate by a ratchet mechanism or other means. The circular disc can be easily sharpened by mounting it on a rotatable shaft. The beveled edge is then engaged with a sharpening stone or file as the disc rotates. Optionally, the tool can include a built-in, self-sharpening mechanism. Here, an abrasive sharpening element is constantly engaged with the beveled edge of the disc. Thus the disc is continually sharpened as the tool is used, and never needs to be sharpened manually.
