The invention relates to a device (1) for isolating and end-rounding bristles affixed to a toothbrush head (5) within a bristle finishing region (7) comprising: (a) means (42, 43) for holding a toothbrush with bristles affixed thereto; and (b) a bristle finishing fork (1) comprising two elongated prongs (2, 3) having tips (10, 10') spaced at a distance "A" defining the width of the bristle swath to be isolated, wherein starting at said tip (10, 10'), the distance between the blades increases to a distance "B" defining the sidewall of the bristle finishing region (7), whereby said fork (1) has a backwards and forwards motion, so that the tip (10, 10') of said prongs (2, 3) can be introduced between toothbrush bristles through a parallel relative motion between fork (1) and brush, so that the swath of bristles to be isolated are positioned in said bristle finishing region (7); and (c) a means (60) for rounding the distal ends of the bristles positioned in said bristle finishing region (7).
