Ron Aho, a sheet metal worker in Marquette, Michigan, knew there had to be a better way to drive cleats than traditional, manual hammering. After years of shoulder damage forced him to undergo rotator cuff surgery, he invented a hammer-drill attachment that could do just that: the Tinknocker Tool.

Aho exemplifies the Michigan entrepreneurial spirit, identifying and solving a problem for the benefit of everyone in the trade. The tool reduces metal workers’ muscle and shoulder fatigue—and drives cleats better and faster.
