ABSTRACT:
An improved scraper hand tool includes upper and lower housing members defining a hollow casing and an operating member axially movable therein to carry a blade between a first interior storage position, a second cutting edge protracted position, and a third blade removal and insertion position. The operating member presents a full beam suspension design wherein a central thumb operating portion projects through a slot in the casing for operative manipulation by a user. Locking detents in the housing interior cooperate with laterally-extending arms on the movable operating member to assure positive positional locking of the blade in each of its respective positions.
