Not everything is so well organized, Alan. Most of the pocket knives are stored in boxes (for the tin boxes, I have to eat a lot of cookies
I keep the smallest ones in plactic bags. I also tag them, so I know when and where I bought them and what I paid.
I'll show you two nice ones. First is dated 1923. I think it's the oldest pocket knife I have. The other one could be considered an etnographic pocket knife. It's a handmade knife from Turkey. The blade has the maker's name stamped on it : BILAL CAN. It has a simple blade and a horn handle.
