A Bowie knife is a pattern of fixed-blade fighting knife created by Rezin Bowie in the early 1800s for his brother Jim Bowie, who had become famous for his use of a large knife at a duel. Since the first incarnation, the Bowie knife has come to incorporate several recognizable and characteristic design features, although in common usage the term refers to any large sheath knife with a crossguard and a clip point. The pattern is still popular with collectors and knife manufacturers alike.
