Columbia 13-14, traditionally one of the most popular universal curettes, is the shortest shank universal curette and very similar to a 204S scaler with a rounded toe instead of a pointed tip. Those that are looking for maximum reach into the posterior and don’t mind very long shanks, the Columbia 4R-4L has a 12 mm long terminal shank and the Columbia 2R-2L has a 14 mm terminal shank. Both of these curettes have elliptical blades that are 50% wider (1.2 mm) than the Barnhart 5-6.
