stylus

A stylus is a writing utensil or tool for scribing or marking into softer materials. Different styluses were used to write in cuneiform by pressing into wet clay, and to scribe or carve into a wax tablet. Very hard styluses are also used to engrave metal, and the slate and stylus system is used to punch out dots to write in Braille.
Styluses are held in the hand and thus are usually a narrow elongated shape, similar to a modern ballpoint pen. Many styluses are heavily curved to be held more easily.
The word stylus is also used to describe computer styluses used to assist in navigating or providing more precision when using touchscreens.
