			Scratchers body and handle
			Plastic Plastic can be found on the handles of the scratcher. Often used is polyurethane, which can be manufactured with different properties. For tools, a strong, hard wearing material with a smooth touch is desired.

			Wood The plasterer’s brush has a wooden body, which is usually made from beech, a strong and hard wearing material.

			Metal On some scarifiers there is a backer plate which is made of aluminium. Aluminium is often used in tools because it is both lightweight and durable.

			Scratchers tines or prongs
			Metal The tines on the scarifier are usually made from steel (stainless or blue), and are slightly flexible to allow for movement when the tool hits a dip or bump. Stainless steel is resistant to rust and corrosion, while blue steel is specially heat treated to ensure it is both sturdy and flexible.

			The pins on the plasterer’s brush are also made from steel. The prongs on a scratcher can be made from an iron based wire.
