Determined to curtail workplace injuries like torn rotator cuffs that are frequent among gas-utility workers, UW-Milwaukee engineering professor Naira Campbell-Kyureghyan and her students designed a solution.

Officials at Snap-on Inc. were so impressed by the design and its potential to decrease injury that they licensed the wrench’s patent and added it to their product line.
