A hand tool according to the present invention comprises in combination, a workpiece assembly and a handle assembly adapted for quick release coupling to one another to provide a manually supported tool having rapidly interchangeable workpieces. The workpiece assembly includes a work head adapted to function as a painting or decorating tool or the like and a support member on the head. The support member has a section of its length disposed rearwardly from the head which extends in a tortuous path to form a first coupler element. The handle assembly comprises an elongated manually engageable handle and a quick release clamp. The quick release clamp comprises first and second jaws which have a clamping face formed with a channel-shaped clamping recess which extends along a tortuous path corresponding to that followed by the coupler element whereby the coupler element may be seated in the clamping recess in a close fitting relationship. The tortuous path in the clamp and on the support member are arranged in a configuration to prevent relative movement between the head and the handle in use.
