Fluted arrow
First Claim
1. An archery arrow having an elongate shaft, a fletching portion at a first end of the shaft, and a tip portion at a second end of the shaft, wherein the shaft has a fluted portion between the tip portion and the fletching portion, wherein the lobes and grooves spiral along the shaft, thereby imparting spin to the arrow and wherein the shaft is tapered at the fletching portion to form a nock adapter, and further comprising a nock attachable to the nock adapter, the nock further comprising an enlarged portion, and further comprising a nock receiver for receiving the enlarged portion, the nock receiver being adapted for attachment to an archery bow string, the nock being rotatable within the nock receiver to allow the arrow to spin about its length.

Abstract
The present invention relates to an archery arrow with a fluted or crimped shaft, which can be made lighter and hence provide greater velocity than a standard, non-fluted arrow. In a second aspect, the present invention includes a fluted arrow wherein the fluting includes grooves that spiral along the length of the shaft, allowing spin to be imparted to the arrow. Spinning the arrow about its shaft will give it increased stability. In another aspect, the present invention includes an arrow rest for the fluted arrow, which is suitably arranged to impart spin to the arrow and/or to keep the arrow from falling off the arrow rest.
