A cutting head for a brush cutter, edge trimmer or similar, the head compris es a passageway (112) for a cutter string (300) and at least one curved surface (120) for supporting the string, the surface extending between an exit regio n (115) for said string from said passageway and a peripheral region of the head. According to the invention, the passageway extends (A) in a manner tha t is offset from an axis of rotation (C) of the head so as to present an insid e edge constituted by its edge closest to said axis of rotation, said inner ed ge corresponding to a trailing edge of the string while the head is rotating, a nd the curved portion extends from said inner edge. This serves to reduce the radius of curvature of the curved portion without needing to increase the diameter of the head.
