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. The silver horse, cowboy, and End of the Trail scene are cut from a 1925 half dollar, set alongside Sleeping Beauty turquoise, 140-million-year-old dinosaur bone, and red coral. Each knife is signed and numbered, so no two are ever alike.
