    Sharpening corner chisels?

    Got a hold of three corner chisels. Wanting to use the tormek to tidy them up a bit. Any advice before I get started? I learn lots of things the hard way and wondered if there were any tips.

    Thanks for your time!

    Aren't corner chisels usually beveled on the inside?

    That would be a real trick to do on a power grinding setup without a special wheel.

    I agree with Jim - hand sharpen only. Even by hand it’s very tricky. Lie-Nielsen has a how-to video on sharpening corner chisels.

    Also, the bevels aren't meant to be straight. Seems the corner hits the surface first, then the outside two ends, then the bevels themselves. At least the ones I've had were sharpened that way, before I rehabbed them.

    My vision was to get them in a jig. Do the dullest side first. They would be only on the ends of the stone. Do the other side to the point it matches the first side.

    This type of feedback is why I asked. Never messed with these before.

    Thanks again for your help!

    Actually...IF you think about the chisel used in a powered mortiser....notice how the corners stick down more than the areas between the corners.....a corner chisel is just one half of one.

    I suggest you get a diamond hone. It will simplify your sharpening.

    Seems like free hand is the way to go.

    Lie Nielsen Video: https://www.youtube.com/watch?v=Jo0IXn0pSic little over 2 minutes in.

    If you have trouble using a stone that you have, you can probably get your feet wet with sand paper on stick (like a paint stirrer or tongue depressor).

    Lowell is smart, Lowell is kind, we should all listen to Lowell. I think I have a set from DMT.

    You could also buy some "slips". Some of these are expensive, but remember the entire start with sand paper on a stick or what we should all listen to Lowell and buy some diamonds.

    Something else to look at here:

    One final thought, when they say that you can use a stone, my opinion is that a thinner stone will be easier. The Lie Nielsen video uses a glass stone, which is pretty thin. What else is pretty thin? A diamond stone.

    Speaking completely out of turn since I have neither used nor shaprened either, I expect that a corner chisel will be similar to a V gouge / carving chisel.

    Will be interested to see what you choose.
