A
brush is a tool with
bristles, wire or other filaments, used for
cleaning,
grooming hair,
make up,
painting,
surface finishing and for many other purposes. It is one of the most
basic and versatile tools known to mankind, and the average household
may contain several dozen varieties. It generally consists of a handle
or block to which filaments are affixed either parallel- or
perpendicular-wise, depending on the way the brush is to be gripped
during use. The material of both the block and bristles or filaments is
chosen to withstand hazards of its application, such as corrosive
chemicals, heat or abrasion.
