Considered by many to be essential for the forming/bending of sides or ribs for stringed instruments of all types. I make these in two sizes, violin 50mm x 300mm and guitar cello 120mm x 500mm. The business part is made from 0.2mm spring tempered carbon steel, blued to help it resist rust and staining. This “blade” is attached to brass finials, in a traditional manner, by copper rivets which in turn provide the anchor for the handles produced in 5mm diameter stainless steel.
