This fine rasp in the foreground was mighty cheap and mighty good in it's day. One of the Chinese swordfish rasps, at some 60 TCM. It cut more like a coarse file but much faster, very little clogging issues. I used it for refining shapes rather than arriving at them. I bought it some 20 or 25 years ago. It's far too dull to be of any use now. I tried to buy it again but without luck. It's hand stitched but if you look closely the teeth are arranged in an arc. The one in the background is much coarser and is one that Fine tools used to sell. The teeth are arranged in a straight line. I don't really care for it much but it's better than a coarse machine cut rasp that I have. The finer one would be ideal for things like saw and plane handles. Even better is that you can bend the tip and then bend it back again when you no longer need that feature. How cool is that! The transition from side to end grain is where a coarse rasp can leave seriously deep scratches that can take a lot to remove.
