Anyone run into a saw plate that was hardened too much to sharpen? I decided to sharpen a Disston miter box saw, around 1900 or so by the medallion and handle. The new Bahco mill file I use for jointing would skate and hardly cut, and when I looked at the file, I was dulling it badly – visible shiny streaks and I could see tooth damage. A dozen passes on the plate and there’s barely a flat spot. The area about a third of the way back from the toe is hardly touched, and I can feel the difference there in filing, it really skates over it. I tried another file I know cuts well, same thing.

This saw appeared to have been used little if any, with only rust from sitting around.

Try posting to this forum if no answer. This is where the Jedi masters hang out.

I’ve heard some use a diamond file for a couple of hard teeth. All or most of the teeth is a different story.

If it’s a modern saw it can’t be sharpened, steel is too hard and designed to throw away
