Hi, I have a 1985 or 86 Buck 639 fieldmate, it's the first year mark < I have read that they were bead blasted, but it looks like powder coating,I like the knife but it scratches easy, I don't like the finish and the way the Kraton handel is getting loose, I'm removing the finish, if it's bead blaster I can have it refinished if I want to sell it, but I'm not sure, I don't think there is a way to tighten the handel. Thanks George
