The clip point is one of the three most common shapes for the blade of a knife (the others being the drop point and the spear point). Clip point blades have the appearance of having the forward third of the blade "clipped" off. The clip itself can be straight or concave.
A Bowie knife (/ˈbuːi/ BOO-ee) is a pattern of fixed-blade fighting knives created by Rezin Bowie in the early 19th century for his brother James Bowie, who had become famous for his use of a large knife at a duel known as the Sandbar Fight.
Since its first incarnation, the Bowie knife has incorporated several recognizable and characteristic design features. However, in common usage, the term refers to any large sheath knife with a crossguard and a clip point, although there are exceptions and special cases. The knife pattern is still popular with collectors; in addition to various knife manufacturing companies, hundreds of custom knifemakers produce Bowie knives with different types of steel and variations in style.
Drop point is a style of knife blade that slopes on the spine of the blade from the handle of the knife to the tip of the blade. This allows the spine of the blade (where the blade is thicker, and thus stronger) to continue forward to the tip of the blade. This way the point is also aligned with the center axis of the knife, eliminating any pitch momentum when stabbing.
The curve on the top of a drop-point blade is always convex, which is what distinguishes it from a clip point blade. The drop point is a common design for hunting.
