  • Patent number: 6994385
    Abstract: An arrow extractor presents a plate having a shelf thereon for placement along one side of an embedded arrow shaft. A locking block on the opposed side of the shaft is movable from a first release position to a second locked position against the shaft so as to clamp the arrow therebetween in a friction fit therewith. Upon pulling on the handle the embedded arrow is extracted from the target. In lieu of a shelf, opposed locking blocks may be used which are slidably movable into position to clamp the arrow shaft therebetween. A handle extends from the plate and is positioned relative to the axis of the clamped arrow shaft so as to effectively transmit the pulling forces exerted on the handle to the clamped arrow shaft.
