ABSTRACT:
A utility tool, such as a scraper, trimmer, cutter and the like, has a tool element and an elongated handle element, the tool element being mounted on the handle element for movement between an extended position in which a working edge portion of the tool element assumes a working position outside the handle element, and a retracted position in which the tool element is accommodated in an internal cavity of the handle portion. The handle element has a cam track, such as a guide slot, and the tool element has a follower pin which guides the tool element during its movement between the two positions thereof. The guide slot has two sections which enclose an angle with one another, one of the sections extending along the front end of the handle element, and the other section extending along a longitudinal marginal portion of the handle element. The front end of the handle element and the associated cam track section enclose an acute angle with the elongation of the handle element. A depression is formed at the front end of the handle element for accommodating a portion of the tool element in the extended position thereof. A socket hole is provided at the rear end of the handle element and communicates with the cavity, being adapted to receive an end of an extension rod. In the retracted position, a part of the tool element may be accommodated in the socket hole. An arrangement may be provided for arresting said tool element in said extended and retracted positions.
