Old thread - I know, but I'm new here. I picked up a couple of these recently. A little rust, but generally good shape (as far as I can tell so far). They have days stamped on the spine (Wednesday, Thursday, etc). Wondering if you ever honed it and how it works. Also, any idea what the scales are made of? One has a wedge pin (guessing added later) and the other does not (although it is broken and would need a pin in order to return to use.
