Russian Black Sable, also known as high quality Russian fitch hair, lies directly between Artist Chungking Bristle and the finest Kolinsky Red Sable hair. It is slightly stiffer and more rugged than Red Sable, but still gives the painter the benefits of Red Sable; its stiffness allows for bristlelike strokes, only smoother without marking the paint layers. In larger sizes, Black Sable Brushes have great color-carrying capacity. Excellent for delicate blending and smoothing out ridges, it is a favorite among portrait and realist painters. Black Sable hair is so smooth that only certain master brushmakers at daVinci can hold onto it without it slipping through their fingers. Seamless, nickel-plated brass ferrules.
