ABSTRACT:
A lightweight renewable hand-held tool that may be easily renewed in the field including a tool head having a tapered shaft, an expandable sleeve, a hollow handle, and a movement assembly for moving the expandable sleeve back and forth along the tapered shaft in response to a rotation of the hollow handle. The expandable sleeve includes a tapered interior that slidably mates with the tapered shaft. Consequently, rotation of the hollow handle adjustably expands the expandable sleeve, forming a tight fit between the tapered shaft and the interior of the hollow handle. The preferred movement assembly is a threaded nut that engages a threaded stud located at a lower end of the tapered shaft. An antirotation fastener is preferably used to prevent the hollow handle from thereafter rotating during use of the tool.
