(57) It comprises a head (1,10) made up by filaments (3,4) laid out in a substantially radial direction on a core or stem (5), and is characterized in that the head (1,10) includes zones made up by filaments (3,4) of different thicknesses.
In the case of a head (10) of frustoconical shape the filaments of smaller thicknesswhich form one of the zones (D) of the head are also shorter.
The different zones (D,E) of the head (1,10) are of different colour, in order to be distinguished from each other.
In the case of a frustoconical head, a hardness substantially uniform in all the zones (D,E) of the head (1,10) is achieved.
