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.
Claims10
A hand-held sharpener device for sharpening short nose curved nail clippers comprising:
- a whetting groove transversely formed in a sharpener supporting V-body block;
- the V-body block having two rectangular flat plate-shaped whetting surface assemblies inclinedly installed on two opposing sidewalls of a V-body block groove such that the whetting surface assemblies form specific preset and changeable angle V-shaped angles;
- the two rectangular plate-shaped whetting surface assemblies protruding beyond the v-block body and forming a cantilevered V-edge lip providing an extended sharpening surface beyond of the V-block body;
- a 1st flat plate-shaped whetting assembly having a rectangular frame with a frame held insert-removable flat plate having two flat sides, a side 1 fitting inside the frame and flush with the V-block, and a side 2 having an abrasive or whetting surface facing a 2nd flat plat-shaped whetting surface assembly;
- the 2nd flat plate-shaped whetting assembly having an installed rectangular frame with an insert-removable held fitting wedge cross-section rectangular perimeter piece having two sides,
- the insertable-removable 2nd frame held fitting wedge cross-section piece angle having numerical values in compliance with a pre-set total V abrasion wedge cross-section specific angles corresponding to sharpener cutting edge cross-section angles, and a side 1 snuggly fitting and held inside the 2nd assembly frame and flush with the 2nd assembly adjacent V-block surface, and a side 2 having an abrasive or whetting surface facing the 1st rectangular flat plat-shaped assembly whetting surface,
- whereby a curved short head nail cutter with a specific angle wedge cross-section cutting edge can be sharpened to its specific angle edge sharpening with the same abrasion surface angle without being impeded by the sharpener block and handle.

A method of short nose curved nail clipper sharpener further comprising the steps of:
- Providing a whetting groove transversely formed in a sharpener supporting V-body block;
- inclinedly installing two rectangular flat plate-shaped whetting surface assemblies on the V-block on two opposing sidewalls of a V-body block groove such that the whetting surface assemblies form specific preset and changeable V-shaped angle groove;
- having the two rectangular plate-shaped whetting surface assemblies protruding beyond the v-block body and forming a cantilevered V-edge lip for providing an extended sharpening surface beyond of the V-block body;
- providing a 1st flat plate-shaped whetting plate assembly having a rectangular frame with a frame held insert-removable fitting flat plate having two flat rectangular sides, a side 1 fitting inside the frame and flush with the V-block, and a side 2 having an abrasive or whetting surface facing a 2nd flat plat-shaped whetting surface assembly;
- providing the 2nd flat plate-shaped whetting assembly with an installed rectangular frame and an insert-removable frame fitting wedge cross-section rectangular perimeter piece having two sides,
- making the insertable-removable 2nd frame held fitting wedge cross-section piece angle with numerical values in compliance with a pre-set total V configuration abrasion wedge having cross-section specific angles corresponding to sharpener V groove cutting edge cross-section angles, and
- configuring a side 1 of the 2nd assembly frame wedge piece snuggly fitting and held inside the 2nd assembly frame and flush with the 2nd assembly adjacent V-block surface, and a 2nd assembly frame wedge piece side 2 having an abrasive or whetting surface facing the 1st rectangular flat plat-shaped assembly whetting surface,
- whereby a curved short head nail cutter with a specific angle wedge cross-section cutting edge can be sharpened to its specific angle edge sharpening with the same abrasion surface angle without being impeded by the sharpener block and handle.
