Duke Cannon doesn't spend all day typing emails on a laptop. He sure as hell hasn't gotten a manicure. His hands build tangible things like V8 engines and two-story decks. And hard work makes hands dirty. That's why Duke Cannon created a Heavy Duty Hand Soap, a rough cut brick formulated with pumice to clean the hands of hard-working men. It is modeled after heavy duty soap supplied to GIs during the Vietnam War.
