Abstract: Disclosed is a modular paint brush comprising a plurality of custom molded and contoured handles that are readily detachable from brush elements using a slide connector with a button stop. Also included is a rotatable brush element. Rotation is achieved through a rotational connector disposed between the handle and the brush element. The rotation of the brush element is governed by a uniform rotation resistance designed into the rotational connector to serve the dual objectives of rotationality and maintaining rotational position of the brush element when the brush is in use after rotation of the brush element. Rapid detachability between the handle and brush element serves the multiple purposes of changing handle configuration with the same brush element for different work environments, changing brush widths for use with the same paint in different work environments, and changing paint colors with the same brush handle.
