Abstract
The hand tool has a shaft with a distal end which is configured to receive any one of a variety of different sized chisel or scraper blades or the like, via corresponding male and female dovetail connections, for example. Storage space for the extra blades, if desired, may be provided in the handle which is secured to the shaft, or may be provided via depressions in a panel of a tool case of the type commonly referred to as 'gift cases'. Where storage space is provided in the handle, preferably this is accomplished by virtue of a spring-loaded collar which overlies lower portions of elongated rotatable cover pieces, preventing rotation. When the spring-loaded collar is retracted, the cover pieces can be rotated, to reveal storage areas on either side of the handle.
