  • Fletch check test arrow
    Patent number: 5423553
    Abstract: A fletch check test arrow comprising a short shaft with a component for blunting a forward end of the short shaft. A fletching is affixed about the short shaft near the forward end thereof. A nock is on a rearward end of the short shaft. When the nock engages a serving portion of a bowstring, it will instantly show an archer if the fletching is touching a grip portion of a bow having an arrow rest, thereby causing a very erratic flight if released.
