Brazilian cherry, also called Jatoba, is extremely hard. I made a cutting (about 1/2" thick) with it and used half a dozen blades (FD-UR #3, if I remember correctly) where I would normally use 2 or 3. The cut edges were extremely smooth and almost mirror-like.
The blades cut well until they start to dull and then it is hard to follow the line. The blade seems to go it's own way and each correction mars the mirror-like cut edge.
Good luck,
Jim
Edit:
I may not have used the best blade for this project. If anyone has suggestions on a more suitable blade, I'd be glad to hear them
