ABSTRACT:
An ergonometrically designed tool handle has a pair of perpendicularly extending hand grips secured at spaced locations along the handle. The tool handle allows prolonged usage by an individual without back strain. The tool handle includes a plurality of intersecting inclined portions which dispose the hand grips in optimal orientation. In a first embodiment, the tool handle has a distal end dimensioned for engagement with a hollow cylindrical socket on a tool head shank. In a second embodiment, a pair of offset sockets are provided on the handle for removable reception of a pair of tool head shanks. An adapter is disclosed which enables conversion of the dual socketed handle for use with single socketed tools. The adapter also provides an angulated extension of the tool handle. The tool handle is designed for use with interchangeable tool heads which may include a hoe, a shovel, a rake, and a scraper.
