Abstract: A new device incorporated in an arrow causes the arrow to spin as it leaves the bow. The arrow spin device comprises a screw shaft which is cylindrical at the leading and trailing ends thereof and inserted in the posterior end of the arrow shaft. A rotary spin is imparted to the arrow shaft about its longitudinal axis at initial bow string release by engagement of the screw shaft with a guide integral with the arrow shaft. As the screw shaft becomes fully inserted into the arrow shaft in response to the bow string's force, the arrow shaft becomes free to rotate about anterior and posterior cylindrical surfaces on the screw shaft. Upon release from the bow string, the arrow shaft is rotating and the arrow will travel faster and with less deviation by virtue of the ballistic spin imparted. This spin allows the arrow to avoid the need for external fletching.
