Brush

It generally consists of a handle or block to which filaments are affixed in either a parallel or perpendicular orientation, 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 intended use, such as corrosive chemicals, heat or abrasion.

It is one of the most basic and versatile tools in use today, and the average household may contain several dozen varieties.

When houses were first inhabited, homeowners used branches taken from shrubs to sweep up dirt, hence using the first brushes.

Configurations include twisted-in wire (e.g. bottle brushes), cylinders and disks (with bristles spread in one face or radially).
