I only own mediocre ones.  I can’t bring myself to spend so much on good ones when I just don’t use them often.  I have a Corradi Sculptor’s file that is kind of a rasp on steroids and a Gramercy Handle Maker’s rasp that handles curves with elegance.

I have heard great things about Corradi Rifflers but the price for a full set requires a
spoonful of sugar.  If you only needed a couple, it’s manageable a la carte though.
