I am listing these items because I received them from an acquaintance who is a carpenter, but I have no use for them. They appear to have originally been a set of 10, but there are only 7 currently. Furthermore, one of them seems to have been purchased later, but the maker of all of them is Toshiaki Tachibana. As I lack specialized knowledge, please check the images. There are scratches, stains, and rust, so please understand this before purchasing. Thank you for looking.
