Hand-Cut Rat Tail Rasps by Auriou

For folks like us who were basically used to the limited range of the Nicholson 49 and 50 rasps, these rat-tailed rasps open a whole new world. This is the perfect tool for working round holes and very tight radii. For fast stock removal, get the longer rasps. For small, precise work, a shorter rasp might be more appropriate.

Auriou uses a scale of 1 to 15 grain to describe the cut of their rasps, with 1 the coarsest and 15 the finest.
