Abstract: A nock that mounts to an arrow shaft. The nock is designed of a light weight plastic material. It incorporates the use of a mechanical locking mechanism to secure it to the end of an arrow shaft. The portion of the nock that is inserted into the arrow shaft, or the insert end of the nock, is expanded by a small set screw located inside a cavity in the insert end of the nock. This expansion of the nock presses against the inside walls of the arrow consequently locking the nock in place. The nock is designed to mount securely to the arrow shaft without the use of adhesives or glue.

Abstract: A multi-bladed expandable broadhead, composite fiber, plastic hunting arrow tip. The tip is comprised of a high strength, light weight fibrous composite plastic material. It incorporates the use of rotatable blades which are trunion mounted securely in the body of the tip, and which are designed to be partially exposed while in flight. The blades are configured such that they will rotate into an expanded position upon impact. The blades are mounted in a forward position with the tips of the blades protruding outside of the tip body.
