Getting tough

My grandfather worked in a blacksmith shop when he was a boy, and he used to tell me, when I was a little boy myself, how he had toughened himself up so he could stand the rigors of blacksmithing.

One story was how he had developed his arm and shoulders muscles. He said he would stand outside behind the house and, with a 5-pound potato sack in each hand, he would extend his arms straight out to his sides and hold them there as long as he could.

After awhile, he tried 10-pound potato sacks, then 50-pound potato sacks. Finally, he got to where he could lift a 100-pound potato sack in each hand and hold his arms straight out for more than a full minute!

Next, he started putting potatoes in the sacks.

Laroy S. Starrett

His first patent (23 May 1865) was for a meat chopper, which he had manufactured for him, but marketed it himself. This product was successful, and his next patents for shoe studs and hooks provided enough income to establish his own factory. He began making a combination square. This was a try-square with a head that could be moved and clamped at any position along the blade, which he patented 26 Feb 1879. He added products including rules, surface guages, and other small tools. His business became the world's largest in his specialty. When he died, it had over five acres of production space, and 1,000 workers.«
