Abstract: A paint brush (201) is provided. The brush comprises a bristle cluster (207) and a handle (202) for holding the cluster. The root end of the cluster is set into adhesive composition by a set depth X. The cluster comprises bristles of two or more different lengths. For a majority of the bristles the difference in length between a longest bristle and a shortest bristle is a range value Y. Y is less than X which means that one end of all bristles conforming to this rule must be embedded in adhesive composition but not all bristles will extend all the way to the tip end of the cluster. This ensures that bristles do not fall out of the handle while providing a tip end with reduced weight.
