Very thin Singletwist knot end brush allows easy removal of scale, splatter, and rust from limited access areas. Single knot wire configuration creates an extra-thin brush while the filament design (twisted in the direction opposite of brush rotation) prevents unraveling and allows extra pressure to be applied. Brush is available in carbon and stainless steels in three wire sizes: 0.006, 0.014, and 0.020 in.
