ABSTRACT:
An extendable tool (10) comprising a handle (12) to be grasped by a hand of a person. A shank (14) is in alignment with the handle (12). The shank (14) has an operable head (16) on a distal end. A structure (18) is for extending the handle (12) lengthwise with respect to the shank (14). An assembly (20) is for retaining the handle (12) in position lengthwise with respect to the shank (14), so that the handle (12) can be lengthened for leverage purposes and shortened to fit into compact work areas and for storage when not in use.
