Starrett Square

"I saw no other way but to try to create a business for myself by inventing something useful that people would want."

"I had worked at pattern making and used clumsy, fixed-blade try squares. I realized the need of a more handy instrument, gave the subject careful study and drew a design that pleased me, and made patterns of it, sitting at the kitchen table night after night until the small hours."

"I secured a foot lathe for my room and after I had made patterns, got castings and a blade for my combination square and took them to a nearby machine shop, engaged the best workman and stood by for two days until he got finished. The man was an expert toolmaker so when it was finished I asked: 'Well, what do you think of it?' He said: 'I would not give a damn for it.' But that did not discourage me. I knew his reason. He believed that the sliding blade in a square stock could not be ground sufficiently accurate to be depended upon, the difficulty being the then almost impossible task of grinding a perfect straight edge to form the blade, due to the heat generated in grinding. I believed the difficulty could be overcome, and it was, so that we were finally able to guarantee our squares standard for accuracy and they are so accepted the world over."
