Abstract: Corrosion resistant instruments such as those used in medicine and dentistry are efficiently made from raw materials that are difficult to machine. Round bar stock is rolled or otherwise deformed to have flat sides and rounded edges. The parts of the instrument are cut from the flattened bar, by combinations of transverse and longitudinal cuts, so that the rounded edges of the bar define the shape of convexly curved finish surfaces of the instrument. Expensive machining steps are eliminated. An orthodontic pliers is particularly disclosed, made according to the method, by making one or more Z-shaped cuts that preserve the rounded sides to define the outer surfaces of a handle and opposing jaw on each of two plier parts, pivotally joined together.
