Retractable abrasive sharpener and carrying case
A hand held retractable abrasive sharpener having a rod formed with a tapered end portion and a partially cylindrical opposite end portion. A part of the partially cylindrical opposition end portion is flat. A slot is formed in the rod. Substantially all of the outer surfaces include layers of the rod have an abrasive material. The rod is carried in a carrying case for tansport and storage in a locked relationship and being capable of being released and withdrawn for sharpening with carrying case serving as a holder.
1. Field of the Invention
This invention relates in general to abrasive sharpeners and, more particularly, to a hand held retractable sharpener for knives, tools, fishing hooks, and the like.
2. Summary of the Prior Art
Many prior art designs have been developed for manually sharpening numerous implements, including knives, tools, fishing hooks, serrated edges and the like. There exists a need in the prior art for an economical sharpener that effectively sharpens knives, tools, fishing hooks and the like at any location. Many prior art sharpeners are inconvenient to use and do not provide for easy transport and storage. It is therefore desirable in the prior art to provide a hand held sharpener capable of quality sharpening of all kinds of knives including serrated edges, a wide range of tools, and fishing hooks utilizing a retractable, easy to carry design.
SUMMARY OF THE INVENTIONIt is therefore an objective of the invention to provide an improved, hand held retractable sharpener and carrying case capable of giving a razor sharp edge to all kinds of knives, tools, and fishing hooks. The sharpener herein is compact and easily carried on one's person, such as in a shirt or other pocket, or in any other transport means. The sharpener of the invention is provided with a durable shaping rod having a round partially cylindrical section and flat surface for sharpening flat or serrated edges, and an opposite tapered conical like section primarily intended for serrated edges. The rod is carried in a hollow carrying case for ease of transport. The rod is secured in the hollow carrying case by a locking mechanism having a tightening cap that retains the rod in the carrying case in a first storage and transport position and in a second sharpening position. In the sharpening position, the carrying case serves as grip able holder in a sharpening mode. The cylindrical section of the rod is provided with a slot for sharpening fishing hooks. Multiple layers of diamond grit abrasives are applied to all surfaces of partial cylindrical section, including the flat surface and the slot, and the tapered section.
BRIEF DESCRIPTION OF THE DRAWINGS
Referring now to
The opposite end section 12 possesses a partial cylindrical configuration provided forming outer surface 12a and a longitudinally extending flat surface 14 (
In
Referring to
In use of the sharpener 2, the rod 6 is released from its carrying position and is pulled out a desired length from the carrying case 4 after which the cap 48 is rotated to retighten the rod 6 to perform a sharpening operation. Upon being tightened with sharpening end sections 8 or 12 selectively exposed, it will be apparent that the carrying case 4 serves also as a holder during a sharpening process. Dependent on which end section is desired to be exposed for sharpening, the rod 6 may be completely removed from the carrying case 4 and reinserted to expose the opposite end sections 8 or 12 as needed.

Claims
1. A hand held abrasive sharpener comprising
- a rod having a first end section,
- said end section having a tapered, generally conical configuration;
- an opposite end section having at least a partially cylindrical configuration;
- said first and opposite end sections having an abrasive surface for sharpening edges;
- a carrying case for carrying said rod in a secured or release configuration, said carrying case having locking means for releasably securing said rod to said carrying case for transport and for selectively releasing said rod to be extended from said carrying case at a projected position for a sharpening operation.
2. The sharpener according to claim 1 wherein said rod includes a longitudinal open slot for sharpening other edges.
3. The sharpener according to claim 2 wherein said opposite section of said rod includes a flat abrasive surface.
4. The sharpener according to claim 1 wherein said locking means releasably locks said rod at said projected position to said carrying case.
5. The sharpener according to claim 4 wherein said carrying case acts as a holder for a sharpening operation in said locked projected position of said rod.
6. The sharpener according to claim 4 wherein said locking means has a cylindrical hollow cap having internal threads, said carrying case having an open end section for receiving said rod, said open end section having external threads for engaging said internal threads of said cap, said cap being moveable on said external threads from a position locking said rod to said carrying case to a position releasing said rod for movement relative to said carrying case.
7. The sharpener according to claim 6 wherein said open end section includes open end slots, said slots being compressible to cause said carrying case to grip said rod in said locking position.
8. In an abrasive sharpener comprising
- an elongated rod having a first end section formed with an outer surface in a tapered shape,
- said rod having an opposite end section formed with an outer surface in a partially cylindrical shape, a section of said opposite end section having a longitudinally extending flat surface,
- a slot formed in said opposite end section, and
- said outer surface of said tapered section, said outer surface of said partially cylindrical section, said flat surface and said slot all having an abrasive outer surface.
9. A hand held abrasive sharpener comprising
- a rod having a first end section,
- said end section having a tapered, generally conical configuration;
- an opposite end section having at least a partially cylindrical configuration;
- said first and opposite end sections having an abrasive surface for sharpening edges; and
- a carrying case for carrying said rod.
10. The hand held abrasive sharpener according to claim 9 wherein said carrying case has means for releasably securing said rod to said carrying case for transport and for selectively releasing said rod to be extended from said carrying case at a projected position for a sharpening operation.
11. In an abrasive sharpener comprising
- an elongated rod having a first end section formed with an outer surface in a tapered shape,
- said rod having an opposite end section formed with an outer surface in a partially cylindrical shape, a section of said opposite end section having a longitudinally extending flat surface, and
- said outer surface of said tapered section, said outer surface of said partially cylindrical section and said flat surface all having an abrasive outer surface.
