Thanks for the replies and I want to go to that Museum! Is it in Kobe?
I do know the difference from western tools although I am no expert.
I am mainly looking for the Orie Nomi (Chisels) and Kanna (planes). Not really the very high end collectable Kanna but tools that were used and that I would also use. I can buy new over the internet but what I really want are the older used tools (which I can find on Ebay somewhat), but seeing as I was going to be there I thought I might have fun tracking some down in person plus It would be interesting to browse around an antique store or two as well.
