Claims19
A scraper actuation mechanism comprising:
- a slider button, wherein the slider button is adapted to slide between a scraping position and a retracted position;
- a rotating stop that pivots between a first position and a second position as the slider button moves between the scraping position and the retracted position, wherein the rotating stop is adapted to prevent the slider button from moving toward the retracted position when rotating stop is in the second position;
- and
- a stop cavity formed within the slider button, wherein the stop cavity accommodates the rotating stop when the rotating stop is in the first position.

A scraper actuation mechanism comprising:
- a slider formed with a slider button at a first end of the slider, wherein the slider is adapted to slide between a scraping position and a retracted position;
- a rotating stop that is adapted to rotate between a first position and a second position;
- a stop cavity formed within the slider button, the stop cavity being adapted to accommodate the rotating stop when the rotating stop is in the first position, wherein the stop cavity has a first end defined by an opening that is open to a bottom side of the slider button and a second end opposite of the first end that is closed to provide a thumb or finger switch;
- a pusher face forming a portion of a rear wall of the stop cavity, wherein the pusher face is adapted to push the rotating stop into the second position as the slider is moved to the scraping position;
- a stop holder face formed on a rear bottom portion of the slider button, wherein the stop holder face is configured to hold the rotating stop in the second position when the slider is in the scraping position;
- and
- a blade release extending from a front base portion of the slider button.

A scraper actuation mechanism comprising:
- a slider button, wherein the slider button is adapted to slide between a scraping position and a retracted position;
- a rotating stop rotatable between a first and second position, wherein the rotating stop has a first end that is attached to a pivot point and a second end that is opposite the first end;
- a stop cavity formed within the slider button, wherein the stop cavity is adapted to accommodate the rotating stop when the rotating stop is in the first position;
- and
