This new steel brush is the product of several years of work to produce the definitive FINE straight steel rotobrush. The straight steel bristles have unmatched "sweeping" efficiency and clear fine structures of even the hardest waxes, without scouring the base. It's taken several rounds of prototyping and the change in the production equipment to reach this point - the key is to have an "uneven" finish to the tufts, and sparse enough spacing so that the brush doesn't overwhelm the work. It's not the prettiest brush, but it's the best brush.
