LOL, You have to be a savvy horse-trader, which I am not. I went to a gun show down in Columbus GA a few years ago and a fellow had several tables full of knives and books, from old to new. At the time I had never handled a Buck Marksman, but he had one new in the box and I asked to see it. I like most things Buck, but being a 110 guy, the strap-lock felt a bit strange, but I knew what they were selling for, so I asked, “how much?” He came back with a price in the $20-something dollar range. I then made horse-trader mistake #1 of asking “are you sure?” He being gracious replied, “Yep, but this is your last chance if I have to get out the book.” So I then made horse-trader mistake #2 and told him the approximate value of said knife and bought a book instead.
