F. J. TONE SHARPENING TOOL Filed Dec. 2 1923 INVENTOR Patented Dec. 23, 1924.
UNITED STATES 1,520,488 PATENT OFFICE.
FRANK J. TONE, OF NIAGARA FALLS, NEW YORK, ASSIGNOR TO THE CARBORUNDUM COMPANY, OF NIAGARA FALLS, NEW YORK, A CORPORATION OF PENNSYLVANIA.
- SHARPENING TOOL.
Application filed December 21, 1923. Serial No. 681,984.
To all whom it may concern:
Be it known that I, FRANK J. TONE, a citizen of the United States, residing at Niagara Falls, county of Niagara, and State of New York, have invented a new and useful Improvement in Sharpening Tools, of wh1ch the following is a full, clear, and exact descri tion.
T e present invention relates broadly to sharpenin tools, and more particularly to tools for s arpening fish hooks.
The purposeof the invention is to provide a sharpening tool so constructed as to adapt it to not only sharpen the point of a fish hook, but also to remove rust or corrosion from all portions of the body of the hook.
The invention is illustrated in the accompanying drawings wherein 0 Figure 1 is a perspective view showing one side of a preferred form of tool embodying my invention;
Figure 2 is a perspective view showing the other side of the tool;
- Figure'3 is an end view of'the tool; and
Figure 4 is a view illustrating the manner of applying the tool to the body of a fish hook for the purpose of removing rust or corrosion from the same.
In the illustrative embodiment of the invention, there is shown a sharpening tool or stone A, the structure and shape of which particularly adapts it for the purpose set forth. This tool or stone may be formed from any suitable material, such as carbo rundum.
The tool is substantially of wedge-shape in cross-section and tapers both in width and thickness from its larger end 2 to its smaller end 3. Being of wedge-shape in cross-section, the tool has a V edge 4 extending the entire length thereof, while opposite the V edge there is a rounded or convex edge 5 also extending the full length of the tool.
It will be noted that the tool has its side face 6 substantially fiat, whereas the side face 7 is convex. In the face 6 there is provided a groove 8 extending longitudinally of the tool from the larger end thereof. This groove is relatively wide and deep where it commences at the larger end of the tool and gradually decreases to zero width and depth at its other end. In the convex face 7 there is formed another groove 9 coextensive in length with the length of the tool and of uniform width and depth throughout its 'length. Obviously the groove 8 might be formed in the face 7 and the groove 9 in the face 6, and, moreover, addltional grooves might be provided if deslred, but ordinarily two grooves, such as shown, will meet all requirements.
The advantages of a construction such as described above as a sharpening tool for fish hooks will be better understood by reference to Figure 4, wherein I have illustrated a conventional form of fish hook. It will be apparent that the point 10 of the book may readily be sharpened by positioning it in either of the grooves 8 or 9 and producing relative movement between the tool and point longitudinally of the groove. By providing a groove 8 of tapering width and depth, such groove may be utilized for sharpening the points thereby obviating the necessity of providing a number of grooves differing in width for this purpose.- The convex face 7 of the tool is adapted to be utilized for removing rust or corrosion from the portion of the body of the hook between a and b and also from the portion of the body between 0 and d, while the flat face 6 of the tool is adapted to clean the straight portion of the hook between 61 and e. The rounded or convex edge 5 of the tool is adapted to clean the portion of the hook between 6 and 0, while the V edge 4 is adapted to be inserted and moved longitudinally in the correspondingly shaped angle a of the barb of the hook. It will beappreciated that the distance between a and b will vary with different sizes of hooks. By providing a tool of tapering width, the portion of a hook between a and b may be cleaned thereby regardless of the size of the hook. Furthermore, by reason of the fact that the tool tapers in thickness from the larger ends towards the smaller end, the size of the angle between the sides of the tool at the V edge thereof decreases from the larger end towards the smaller end of the tool. This enables the V edge of the tool to be insorted in the angle a of the hook, regardless of the size of the angle.
Thus it will be seen that the shape of the tool and the form of the grooves particularly adapt the tool for the purpose intended, namely, the sharpening and cleaning of fish hooks, but its use is not necessarily limited in this regard, as it may have other utility.

Ill)
while I have shown and described a pre- 3 ferred embodiment of my invention, it will be understood that the invention is not limited to the exact details of the construction shown, but that it may be otherwise embodied within the scope of the appended claims. 7 v
I claim:
1. A sharpening tool, comprising a body substantially wedge-shape in cross-section to provide a. V edge, said body having a longitudinally extending groove in one face thereof, said groove being relatively narrow with respect to the width of said face, substantially as described.
2. A sharpening tool, comprising a body substantially wed e-shape in cross-section to provide a V e 'ge, said body having a longitudinally extending groove in one face thereof tapering in width and depth from end to end, said groove being relatively narrow with respect to the width of said face, substantially as described.
3. A sharpening tool, comprising a body substantially wedge-shape in cross-section to provide a V edge, said body tapering in width from end to end and having a rounded or convex edge opposite said V edge, said body having one of its side faces substantially flat and provided with a lon 'tudinally extending groove therein and aving its opposite side face convex and provided with a longitudinally extending groove therein, substantially as described.
4. A sharpening tool, comprising a body substantially wedge-shape in cross-section to provide a V edge, said body having a rounded or convex edge opposite said V edge merging smoothly with the side faces of the body, one of said side faces being substantial y flat and the other convex, and one of said side faces having a longitudinally extending groove therein, substantially as described.
In testimony whereof I' have hereunto set my hand.
- FRANK J. TONE.
