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.
