Want a knife no one else will own? This is it. A U.S.A.-made Buck knife completely reworked, signed, and stamped by the artist Ghostown. It features a 1925 half dollar (the bear and tree), Sleeping Beauty turquoise, 140-million-year-old dinosaur bone, and dark blue lapis. Each knife is signed and numbered, so no two are ever alike. You will never see a knife like this again.
