Hand-Cut Curved Rasps by Auriou

Curved rasps only have teeth on the outside, convex side. They are used to work hollow surfaces, such as the seat of a chair or the inside of a bowl. This type of rasp is available only in fairly large sizes and in coarse grains. They are made for rapid removal of stock. Because of their random hand-made tooth pattern, they nevertheless cut fairly finely. However, expect to follow up the surface with scrapers and other finishing tools.

Auriou uses a scale of 1 to 15 grain to describe the cut of their rasps, with 1 the coarsest and 15 the finest. For more information of grain (the degree of fineness or coarseness) other terminology, and how to use and care for your rasps click here.
