I had, and used, a #49 & #50 for over twenty years, then somebody walked off with the #49 at a selfbow jamboree. Bought and tried a new #49, it was a piece of junk. Went to Lee Valley tools and ordered a Auriou 12” cabinet rasp 8g-left (yes the left is for left-handed and it makes a difference). Told my wife it was my Christmas present, it is one of the best Christmas presents I have ever received. By far the best file I have used, including my Torges two handled file from Japan. It is more than twice the price of a Nicholson but is worth every penny.
