ABSTRACT:
A scraping system for facilitating changing of a blade and cleaning after scraping a surface includes a base member. An upper extension is attached to the base member and extends upwardly at an angle with respect to the base member. A lower extension is attached to the base member and extends downwardly at an angle with respect to the base member. A lower arm is coupled to the lower extension. An upper arm is pivotally coupled to the upper extension of the base member. The upper arm is pivotal towards the lower arm to abut the lower arm. A blade is positioned on the lower arm. The upper arm is biased against the lower arm and the blade to press the blade between the upper and lower arms and inhibit sliding of the blade when the blade is scraped across a surface.
