I’m pretty sure I posted this before but it was a long time ago and I just had a reader named Steve ask me about this in the comments on another post.
It sounds crazy but I actually tried it and it works.
He also asked if there was any way to sharpen some old files he has laying around.
There are all kinds of people claiming that you can do that if you look on Youtube but I’m pretty much calling bullshit.
Once the cutting edge has been dulled I have not found a good way to get down in those little grooves to make them deeper and cut a new edge.
Getting them as clean as possible will usually help but once that edge is rounded off they are only good for material to make other things out of, like knives.
That’s my $.02, YMMV.
Because invariably I am going to get comments saying that yes you can sharpen files,
I went and did some more digging.
Turns out I found this video made by not only a machinist, but a machine shop teacher, who took the time to explain how to sharpen your files.
