1. If you just nudge and tease out the chips then, no, it doesn’t dull it. If you scrape the chisel across the bottom of the mortise, then yes. Some scraping always seems to happen at least a little. I don’t think it is worth having a separate chisel: Narrow chisels sharpen quickly. Quite often, I take shavings off of the bottom of the mortise with the narrow chisel to flatten the bottom. Only a portion of the mortise can be reached this way, but it is still useful, useful enough that I want a real chisel, not a “this is junk I don’t care about it” chisel. It really isn’t a big deal.

  1. Everything you do cutting wise dulls a chisel. If you don’t want to use a chisel you could use a screw driver or a paint can opener or anything else that is small thin and sized to fit in the hole

  2. One thing I sometimes wonder about is how often Paul sharpens his chisels and other tools. He seems to go a long time, or perhaps he does not show all the times he sharpens. On the other hand, the longer I do woodworking the more often I find I sharpen chisels (and planes and saws). This is partly because sharpening gets faster and easier with practice so I just routinely do it a lot For a while I used various things, such as paint can openers and old dull chisels, to leverage out waste from a mortise hole, as deanbecker mentions. But I no longer do. I just sharpen regularly and do not worry much about dulling a chisel. Actually, I am more concerned about breaking a chisel when leveraging out waste wood, though I have not done that so far!

  3. Exactly. A chisel is made to be sharpened just like a plane or knife when it gets dull.
    I think you are sharpening as you are supposed to when you feel the edge falter. In some woods it’s 2 minutes in others it’s 15.
    I Think the thing we look for is when it’s not sharp enough.

  4. I like the leg/support design; it seems to have a bit of Cubism &/or Bauhaus design elements. I like the design of all the Sellers Home pieces.
    As always, excellent job at teaching, demonstrating & craftsmanship Paul. The entire WWMC team produce consistently great content.
    Thank you all.
