My Auriou rasp's arrived yesterday, and I have to tell, you, there is no comparison. Having used both now, I can truthfully say that the Nicholson is junk compared to the Auriou. I'm not saying the #49 won't get the job done, but it's a 1 HP and the Auriou is an 8 HP. Those of you who already have them know what I'm talking about. Many thanks to those who recommended it.
