Pictures are here:
I inherited this tool from my father and I've been referring to it as a "checkering file," although that might not be the correct name. The tools is about 10 inches long, .5 inches square, with eight different cutting faces, each one containing a differently spaced set of parallel teeth. Great for evenly spaced crosshatching or serrated grips, and is clearly intended for metalworking.
It was already pretty dull when I got it years ago, but now it is positively useless and I want to do one of two things:
- Replace it with a similar quality tool, but I don't know the correct name, the manufacturer doesn't seem to exist any more, and I must be using the wrong search terms at MSC and McMaster because nothing like it shows up in their inventory. Brownell's carries checkering files but they are nothing like this beast.
or
- Sharpen the existing tool, if there's a way.
Can any of the knowledgeable people in this ng help me with either of those two options?
Many thanks, as usual.
