Abstract
A curved nail clipper or cutter sharpener having a specific angle V-block abrasive surface with lip having clearance for small jaw short clipper curve cutting edge. A whetting groove transversely is formed in a sharpener supporting V-body block such that the whetting surface assemblies form specific preset and changeable angle V-shaped angles.
Claims5
A hand-held sharpener device for sharpening short nose curved nail clippers, comprising:
- a V-block handle;
- a V-body block having a whetting groove, the whetting groove extending transversely across the V-body block;
- the V-body block having two rectangular flat plate-shaped whetting surface assemblies configured to be inclinedly installed on two opposing sidewalls of the V-body block, the whetting groove extending between the two opposing sidewalls, groove-such that the rectangular flat plate-shaped whetting surface assemblies are configured to form specific preset V-shaped abrasion angles;
- the two rectangular flat plate-shaped whetting surface assemblies each comprising a length extending across and protruding beyond the V-body block, and forming a cantilevered V-edge lip providing an extended sharpening surface beyond the V-body block;
- a 1st flat plate-shaped whetting assembly, of the two rectangular flat plate-shaped whetting assemblies, having a rectangular frame configured to removably hold an insertable first flat plate in the V-body block when the rectangular frame is installed on a first opposing sidewall of the two opposing sidewalls, a first side of the first flat plate fitting inside the rectangular frame that is parallel and flush with the first opposing sidewall, and a second side of the first flat plate having an abrasive or whetting surface;
- a 2nd flat plate-shaped whetting assembly, of the two rectangular flat plate-shaped whetting assemblies, having a rectangular frame configured to be installed on a second opposing sidewall of the two opposing sidewalls, the rectangular frame of the 2nd flat plate shaped whetting assembly configured to removably hold a plurality of insertable wedge cross-section rectangular perimeter pieces, wherein each wedge cross-section piece has two opposing flat sides,
- wherein the two opposing flat sides of each of the wedge cross-section pieces are disposed at an angle relative to one another, wherein each angle is a pre-set numerical value comprising one of a plurality of V-block wedge cross-section specific angles, and
- wherein a first flat side, of the two opposing flat sides of each of the wedge cross-section pieces, is configured to fit and be held inside the rectangular frame of the 2nd flat plate-shaped whetting assembly in a manner that is flush with the rectangular frame of the 2nd flat plate-shaped whetting assembly,
- wherein a second flat side, of the two opposing flat sides of each of the wedge cross-section pieces, has an abrasive or whetting surface facing the abrasive or whetting surface of the first flat plate when the first flat plate is inserted in the rectangular frame of the 1st rectangular flat plate-shaped assembly, and
- whereby together the abrasive or whetting surface of the first flat plate, inserted in the rectangular frame of the 1st flat plate-shaped whetting assembly, with each one of the abrasive or whetting surface of the wedge cross-section pieces form the specific preset V-shaped abrasion angles, and are configured to sharpen a short nose curved nail clipper without being impeded by the V-body block and the V-block handle.
