A bristle brush has a head with a multiplicity of closely spaced recesses in one surface thereof and in which are disposed bristle tufts of U-shaped configuration which extend outwardly thereof. The tufts are comprised of multiple bristles and have a bight portion disposed adjacent the bottom of the recesses and vertically extending leg portions. Staples are disposed between the leg portions of the tufts and pressing the bight portions downwardly in the recesses. The staples have a body portion of generally rectangular cross section and of greater length than the diameter of the recesses. A multiplicity of ribs are provided on at least one side surface and extend transversely thereof. The ribs are spaced apart in the vertical direction a distance at least three times the width of the ribs, and the ribs are of substantially lesser height than the thickness of the body portion. At least some of the ribs are embedded in the material of the head about the recesses.
