Abstract

A paintbrush (1) having adjustable control of bristle length comprises a handle (2), a plurality of bristles (3), an inner ferrule (4) and an outer ferrule (7) mounted on the inner ferrule (4). The outer ferrule (7) comprises at least one moveable portion (8) arranged to surround the bristles (3), the at least one moveable portion (8) being moveable from a retracted position along the bristles (3) to an extended position wherein the at least one moveable portion (8) surrounds the bristles (3) along at least a portion of the length of the bristles, the extended position being selected to provide a desired amount of bristle length beyond the distal end of the moveable portion or to extend beyond the length of the bristles.
