What is arrow fletcher?

An arrow fletcher is a tool that is used in archery to attach feathers or vanes to the arrow shaft. The feathers or vanes are attached in a specific orientation to create spin or stabilization of the arrow in flight. Historically, fletching was done by hand using natural feathers, but modern arrow fletchers use synthetic vanes and specialized machines to attach them. Arrow fletchers can also be used to repair or replace damaged or worn fletching on arrows. Fletching is an important aspect of arrow construction as it greatly affects the accuracy and trajectory of the arrow.
