Some Black Diamond bandsaw filing and setting machines have been seen with a patent date corresponding to a 1909 patent granted to Artemas C. Ambler of Natick. He had earlier been co-inventor on machines related to boot- and shoe-making. In 1939, George B. Ambler of Natick was granted a patent for a twist-drill sharpening machine. That patent was assigned to Black Diamond Saw & Machine Works.
