Patent attributes
An arrow insert is inserted into an arrow shaft. The arrow insert includes an outer end with a head, which is located against a leading end of the arrow shaft. An interior diameter of the arrow insert is machined as to accept a threaded arrow tip. To assemble the arrow insert with the arrow, the neck of the arrow insert is coated with an adhesive and inserted into the arrow shaft. The head of the arrow insert has an angular undercut, which is substantially concave. The angular cut of the head is a mating surface for an angular cut on the leading end of the arrow shaft. The substantial concave surface of the arrow insert and the substantial convex surface of the arrow tube prevents the rearward movement of the arrow insert, and the mushrooming of the leading end of the arrow shaft.
