Abstract
A blade scraper has a hand grip casing with a blade storage compartment and a slide mounted in a chamber of the casing for holding a razor blade and permitting retraction of the razor blade into an inoperative position and sliding movement to an operative position with the blade in a scraping position exposed outside of the chamber. A pressure sensitive locking button acts to lock the blade in the inoperative position or the exposed position. A safety button is interconnected with the slide so that pressure must be applied to two actuating buttons in order to expose the blade thus making it difficult for small children to accidentally place the scraper in a mode of operation dangerous for handling. The slide carries a safety dowel for locking the blade compartment when the blade is locked in its inoperative position.
