I haven’t used it except for that little test on the 2×3, I’m not sure it’s any faster than any other large tooth rasp, but there is a coarse and fine side. The fine side leaves a fairly clean surface. That was noted in the reviews and it seems to be reasonable. Time will tell. I’m going to try to sneak into the shop and give it a try. Since it’s a hand tool (quiet) I can use it at night. ;-)
