Abstract
A comb comprised of an elongated back having integral substantially parallel teeth extending therefrom. A bubble-type level is rotatably mounted within a first recess provided in the comb back. The level is mounted to rotate about its longitudinal axis and is provided with a plurality of projections spaced at predetermined angular intervals arranged along one end of the level for cooperation with a second recess to form a "click-lock" arrangement with the second recess provided in a cooperating sidewall of the first recess to automatically lock the level into the desired orientation which may, for example, be right-lock, center-lock or left-lock orientations. The level facilitates leveling of the comb during use.
