The name Odd Jobs denotes that the tool does many kinds of sundry tool roles. Its closest cousin among common, modern tools, is the combination square, which shares with the Odd Job the functions of scribing, squaring, level/plumb, and the sliding and locking ruler (originally a 12 inch wooden ruler with a built-in trammel point was included with units bundled with a ruler, but this was often changed and many are found with a steel rule, or a brass-bound four-fold rule --- the Garret Wade reproduction uses a brass bound wooden ruler). However, the Odd Jobs still has some unique functions in its total package, including the compass, and compensated gauging.
