David:
Thanks for your help on this.
You have been a great help!
That walnut handled knife has a bit of history. It is an old #8 that one of my daughters found while we were in the woods in a valley between the Selkirk and Monashee mountain ranges in British Columbia about 25 years ago. We lived there at the time. Anyway, I kept that knife and really didn't do anything to it until this year, when getting inspired by the Opinel mods that I saw because of this forum, I decided to go nuts with it.
I totally disassembled the knife and found that the pivot pin was bent, but the steel inner collar, the lock and the blade were good. I put together an oversized block of walnut for the handle and fitted it for the blade and locking system. Then I carved the bearded head on the handle, and reprofiled the blade to make it a better carver. Reassembly and some boiled linseed oil, and there it is
