The flat blades are 10 mm long and 1.5 mm wide and are sharp around the entire periphery. The blades are 0.4 mm thick to enhance interproximal access. The tips are made from spring-tempered stainless steel to give the blade a slight flexibility and to resist breakage. Interproximal carvers are designed to trim and shape interproximal surfaces. They have a slender profile for easier access to tight contact areas.
