Bonsai tools aren't actually very old in the scheme of things. The first concave cutter, for example, was developed by Kyuzo Murata (proprietor of Kyuka-en) and developed in assocation with Masakuni Kawasumi around 1930. They were working on some bonsai-specific shears a few years before.
If you have mass-produced tools older than this they are likely either for flower arranging or perhaps some other type of gardening. Of course they could be someone's rare prototypes!
