Abstract
A handle for use in production of brushes by fusion. The handle is injection molded with a set of pre-formed holes. Each hole contains, on its bottom surface, a protrusion of excess material. Bristles for the brush are heated to form a small fuse at their ends. When the fused ends are inserted into the holes, material from the protrusion flows around the fuses, retaining them in the holes upon cooling.
