This is a Buck 121 Vintage Fixed Knife. Manufacture date mark of 1991. Looks like it was barely used. Some minor tarnish from age.
The blade edge and tip are nice. See lots of photos of what you are getting.
Includes the knife, original sheath, some paperwork, and rough original box seen above. The paperwork has some bends. The registration card has some creases and small rips. The box has wear, creases, indents, and a longer side rip near one end. View my other listings for more quality items. I look forward to doing business with you. That is where you item will be sent.
