ABSTRACT:
An elongated dovetail tongue on the top surface of the trowel blade slips endwise into a closely conforming groove formed in the base of the removable handle until its end abuts a shoulder at the end of the groove. The tongue is longer than the groove, and a keeper is adapted to slip onto and abut the end of the tongue protruding from the groove. A boss on the end of a resilient arm extending from the keeper engages a detent in the base, locking the keeper to the handle, immobilizing the tongue, and thereby securing the handle to the blade. Disengaging the detent mechanism releases the keeper and allows it to be removed and the handle readily separated from the blade. In the preferred embodiment, the tongue comprises a pair of upwardly divergent flanges attached to the top surface of the blade, and the groove is defined by the downwardly convergent walls of a channel formed in the underside of the base,
