The inventor Charles Morrill introduced a saw set with a plunger based on his patent. This design, as well as improvements added to it, came into prolific use and in the United States are frequently found with woodworking tools. An image of a Morrill design saw set is found at the introduction of the article. The plunger (also, pin) pushes against the saw tooth when the handles are squeezed together. The other face of the saw tooth rests against an anvil and the whole saw blade is held at the desired angle to the anvil by a stop or rest. On most designs both the anvil and the rest are adjustable.
