Maulstick

A mahlstick, or maulstick, is a stick with a soft leather or padded head used by painters to support the hand with which they hold their paintbrush. The word derives from the Dutch maalstok 'painter's stick', from malen 'to paint'.

In 16th- through 19th-century paintings of artists, including self-portraits, the maulstick is often depicted as part of the painter's equipment.
