ABSTRACT:
A knife and scissors sharpener with a guard for the former. The scissors sharpener has an opening for each blade of the scissors with a cylindrical sharpening stone extending across them. The stone may rotate about an axis perpendicular to the openings to allow its positioning parallel to the cutting edges of the scissors to effectuate the sharpening of the blades. A spring normally keeps the cylindrical stone in one position, but the force exerted on the scissors' handles will cause the stone to move to its proper orientation. The knife sharpener employs two tungsten carbide sharpening elements crossed to form two V's. The sharpening elements in one V have a configuration for effectuating knife sharpening. In the other V, the elements will hone a previously sharpened knife blade. A circular disk holds the crossed sharpening elements in the handle. Rotating the holder 180.degree. permits a change between the sharpener and the honer. A guard attaches to the holder and can rotate between opened and closed positions. In the open position, it permits the use of the sharpener and honer. To use either of these involves holding the edge of the entire mechanism on a surface. In its open configuration, the guard drops down and protects the surface from a knife undergoing sharpening. In its closed position, it rotates up against the holder so that it will occupy minimal additional space.
