Abstract
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.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
113 words
The method for extracting an arrowhead which comprises: a. removing an arrow shaft from a detachable type of arrowhead having sharp edges for hunting embedded in an object such that the head is exposed; b. attaching a slide percussion tool with a linearly slidable housing mounted on a shaft with a percussion stop to the arrowhead; c. repeatedly sliding the housing in a direction which approximates the direction of entry of the arrowhead into the object in order to remove the arrowhead from the object by hammering the housing against the stop; and d. inserting the arrowhead into the object where it was embedded in order to detach the arrowhead from the tool.
Claim 2
Independent Claim
113 words
The method for extracting an arrowhead which comprises: a. removing an arrow shaft from a detachable type of arrowhead having sharp edges for hunting embedded in an object such that the head is exposed; b. attaching a slide percussion tool with a linearly slidable housing mounted on a shaft with a percussion stop to the arrowhead; c. repeatedly sliding the housing in a direction which approximates the direction of entry of the arrowhead into the object in order to remove the arrowhead from the object by hammering the housing against the stop; and d. inserting the arrowhead into the object where it was embedded in order to detach the arrowhead from the tool.
Claim 3
Dependent Claim
17 words
The method of claim 1 wherein the sliding housing is rotatable on the shaft which is round.
Claim 4
Dependent Claim
43 words
The method of claim 1 wherein the shaft is rotatable in the housing and is threaded onto the arrowhead by rotation of the shaft by hand onto mating threads on the arrowhead and then tightened by selectively locking the shaft to the housing.
Claim 5
Dependent Claim
14 words
The method of claim 1 wherein the arrowhead is embedded in wood while hunting.
Claim 6
Dependent Claim
13 words
The method of claim 1 wherein the arrowhead threads into the percussion tool.
