Mark Manger grew up in Denver, Colorado, and studied visual arts. He was inspired to invent this unique tool when he was teaching art in Ghana with the Peace Corps. “Every bar had these cool, hand-made openers consisting of a piece of wood with a couple of screws stuck in it,” he remembers. “The screws hooked under the cap and the cap was pried off as you press down on the wood. It was brilliant!” Over time, Mark thought about different configurations based on this principle, developng it until the form and balance worked with the motion of the hand. “It designed in a way that accommodates amputees, stroke victims, and others who may only have full use of one hand.” Formerly an editoral photographer, Mark now lives in Missoula, Montana, with his wife and son, and is a full-time inventor and entrepreneur.
