Benefits of technology
[0005] It 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.
Problems solved by technology
Many prior art sharpeners are inconvenient to use and do not provide for easy transport and storage.

Embodiment Construction
[0014] Referring now to FIGS. 1, 2, and 3 there illustrated the hand held retractable abrasive sharpener of the invention, generally designated by reference numeral 2. In separated form as shown in FIGS. 1, 2, and 3, the carrying case 4 is shown and with be described later. The abrasive sharpener 2 includes a solid, one piece rod 6 that is formed from a metal material, such as steel, aluminum, and the like. The rod 6 possesses an end section 8 in a tapered shape commencing from a maximum outer diameter at area 8a and terminating in a near pointed end 8b. The end section 8 is formed in a frusto-conical or near conical configuration to define the tapered shape and form outer surface 8c.
[0015] The opposite end section 12 possesses a partial cylindrical configuration provided forming outer surface 12a and a longitudinally extending flat surface 14 (FIGS. 2 and 3). A cylindrical mid-section 16 separates the tapered end section 8 from the opposite, partially cylindrical opposite end sect...

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.
Description
BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] 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. [0003] 2. Summary of the Prior Art [0004] 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 INVENTION [0005] It is therefore an objective of the in...
