In 1888, Stanley Tools introduced its “Convenient Tool,” the original Odd Jobs, which was later marketed as “Ten Tools In One.” For 47 years, carpenters relied on the versatile metal gadget as a tri-square, spirit level, miter square, scratch awl, rule, marking gauge, mortise gauge, depth gauge and beam compass. It was discontinued in 1935, but some manufacturers, like Garrett Wade and Woodpeckers, still sell modern versions.
