Which tool features a chamois tip and is used to steady the arms while painting?

The tool recognized for featuring a chamois tip and aiding in the steadiness of the arms while painting is the mahl stick. This long, thin tool is typically used by artists to support their arms, minimizing tremors or unintended movements that could disrupt their work. The chamois tip provides a soft, non-damaging surface that can rest against the canvas or painting surface without marking it, allowing for greater precision in detail work. This is particularly advantageous during fine painting processes where stability and accuracy are crucial. By using a mahl stick, artists can focus on achieving clean lines and delicate details without the concern of smudging or accidentally touching the wet paint with their hands or arms.
