Hi guys… just wanted to run something by those who have and use rasps. I have three 7 inch Auriou modelers rasps. Two are the 13 grain and the other is 10 grain. I also have an Auriou cabinet rasp 9 inch 10 grain. After a fair amount of work, I noticed that the 7” and the 9” rasps I originally purchased were not cutting as well as when I received them. I ordered another 7 inch and sent the dulling 7 and 9 inch rasps in to have them sharpened. I received the new second 7” 13 grain and started using it. I just didn’t seem that aggressive so I ordered an additional 7” 10 grain. I received it and it doesn’t seem that aggressive or “sharp” either. The sharpening company I sent the original two to returned them (sharpened) and I began using them. I was shocked at how much better they cut, and seem to have retained the sharpness so far. Does this make any sense? As I remember the original 7” and 9” rasps cut pretty well in the beginning, but the 2nd 13 grain and the 10 grain 7” rasps I recently purchased just seemed somewhat dull out of the package. Anyway, has anyone else had this experience …. where the brand new Aurious were improved by a commercial sharpener. The company I used is called Boggs Tool (in California). They apparently use a method called “abrasive blast liquid honing”. I was shocked when I compared the “new” 7” 13 grain to the newly sharpened 7” 13 grain. The 9 inch after being sharpened, performed better than when I first purchased it. This was especially true on the back flat side.
Thoughts?
