According to my experience, this set is exceptional for anyone looking for a quality abrasive brush for their industrial and scientific use. The curved design and stainless steel and brass construction ensure that even the toughest grime and dirt don't stand a chance. The handles are comfortable and provide an excellent grip. The only downside is that there aren't enough pieces in the set, but the performance more than makes up for it. Overall, a great investment for anyone in need of a reliable abrasive brush set..
