Abstract: A retractable blade scraper includes an elongated handle having an upper surface, a lower surface, a left side, a right side, an open forward end and a rear end. Included in the handle is an integral blade slide housing that begins at the open forward end and extends longitudinally rearwardly toward the rear end of the handle. Slidably received and retained in the housing is a blade slide with a blade platform for removably retaining a scraping blade such that its scraping edge is substantially perpendicular to the longitudinal axis of the handle. The blade slide is longitudinally reciprocable within the housing between a forwardmost blade-changing position in which the blade platform extends out of the housing, beyond the open forward end, by an amount sufficient to permit the removal and replacement of scraping blades therefrom and thereon and a rearwardmost blade-storage position in which the scraping edge of a scraping blade in place on the blade platform is housed within the housing for safety.

Abstract: A scraping tool employing a sharp-edged blade such as a wallpaper shaving blade, utility or razor blade; comprising an integral body and handle, a controllable quick-release blade clamp and latching level to lock and unlock the clamp for access to the blade. Both the clamp and lever are pivotably connected to the body/handle component using the "snap-fit" technique. The tool includes an integral resilient member for maintaining the clamp closed whenever the tool is unlocked, such that the blade will be retained at all times, until the clamp is purposefully actuated by the user for installation or removal of the blade.
