I use the 49, 50 and ferrier's rasps all for different things. Bought a 1/2 round mill bastard recently, and still have 2 or 3 small combo rasps I reach for instinctively. I haven't tried the UBR rasp, but take the good word I hear to heart. Long way of saying, one's first rasp might well should be the ferrier's rasp, but at least for some of us there's room in on the bench for some others, at least given sufficient time and budget. I reckon I need to get busy and order me an UBR, perhaps fetch me up a copy 'o dat movie too. I hear the music was real good. LOL
