Another vote for Iwasaki (first I reach for), also Miicroplane rasps (I have a #13 Auriou). Tools for Working Wood used to sell an sbsolute lovely 4 in 1 file rasp, rounded one one side, flat on the other, with fine and coarser teeth. I used mine last week and after the years, it is becoming a bit dull. Looking through the TFWW website, I don't see it listed anymore.
