Hake brushes use ultra soft hair arranged in a flat base and with a flat handle. Most of the time, the hair is sheep, which holds a storm's worth of water and is sufficient for ample washes and long wet strokes. Sumi-e painters and calligraphers use hake brushes to wet paper or for broad applications of water or ink.
Other fine artists use hake brushes for the even application of water media, glue, or sizing. Ceramic artists like the way a hake brush lays glazes. Breakable hake brushes can be pulled apart and then used in smaller sections.
