  • Patent number: 4150469
    Abstract: A novel tool and method for extracting arrowheads from stumps, trees and the like using a linearly slideable housing or hammer mounted on a shaft which is attached to the arrowhead is described. In particular, the tool is provided with a retaining means to hold the shaft in the housing to prevent accidental movement and thus noise in use in the field. The tool preferably has a round shaft which is rotatable in an extended position in the housing which facilitates arrowhead extraction during linear movement and which in its retracted position in the housing engages a locking means which holds the shaft from rotational movement to permit threading of the shaft onto and off from the arrowhead by rotating the housing.
