I have a puukko that is marked OK on blade. The guy that had it before me had notes that stated it is model T77 from KP line. I called Kellam knives and was told it's very rare desirable knife with less than 30 made for retiring chief of staff. I've tried finding more info and value of this knife. Don't know how to attach pics as I use my phone but is gorgeous knife. Any help and info appreciated.
