Backscratcher

A backscratcher (occasionally known as a scratch-back) is a tool used for relieving an itch in an area that cannot easily be reached just by one's own hands, the acnestis, typically the back.

They are generally long, slender, rod-shaped tools good for scratching one's back, with a knob on one end for holding and a rake-like device, sometimes in the form of a human hand, on the other end to perform the actual scratching.

Though a backscratcher could feasibly be fashioned from most materials, most modern backscratchers are made of plastic, though examples can be found made of wood, whalebone, tortoiseshell, horn, cane, bamboo, ivory, baleen, and in some cases in history, narwhal tusks, due to the status afforded by relieving itches with a supposed unicorn horn (an example of conspicuous consumption).

[1] In recent history backscratchers were also employed as a kind of rake to keep in order the huge "heads" of powdered hair worn by ladies in the 18th and 19th centuries.

[2] In the past, backscratchers were often highly decorated, and hung from the waist as accessories, with the more elaborate examples being silver-mounted, or in rare instances with an ivory carved hand with rings on its fingers.
