20140199919 | TOOL FOR ROUNDING OFF CORNERS OF FRETS - A file having concave portion is most well-known. The use of this file has a risk of mining an effect of a leveling of frets due to undesirable scrape of a top portion of the fret and to losing a normal function of the fret due to a change of the height thereof. Since the file is held by hand, a tool angle varies in use. Since the size of a polishing surface of the tool is not suitable for all types of frets, a complete set including a various size of the files is required in order to select and use one of them as necessary and appropriately. Therefore, a tool of the invention has been made to solve these problems as follows: 1. the top portion of the fret is not scraped and the resultant fret after the leveling thereof are protected as important: 2. since the tool is placed on the fretboard with two side portions of the tool, and thus the tool angle is kept constant (thus, during use the axis of the tool is not rotated and the centerline of the tool is not displaced): 3. one model of the tool may be used for all types of frets; and 4. all the frets take a fine symmetrical shape. | 07-17-2014 |
