I've got a very nice Laguiole Le Fidele with olive wood scales I received as a gift many years ago. A couple of years ago something fell on it and broke a piece of one of the olivewood scale, near the pin on the one end. Is there is easy patch for this? I mean, I don't want to replace the whole scale, but it feels slightly uncomfortable in my hand. Can I put some sort of putty or something in? (Unfortunately the piece which chipped out in lost.) Or something else which doesn't require replacing the whole scale?
