The Faithfull Piercing Saw, often called a jewellers saw, is essentially a smaller version of a coping saw. It is fitted with an extremely fine blade and is specifically designed for cutting thin sheet metal up to 1mm thick, such as aluminium, copper, brass, gold and silver. The steel frame is adjustable to accommodate different blade lengths allowing broken blades to be re-used. A lubricant such as beeswax can be used for smooth cutting performance.
