You can also use metal cutting blades. They have little set and small teeth. They cut on the upstroke, but because of the small teeth, there is very little tearout. Do do have to cut slowly though; if you don't the gullets between the teeth will fill with sawdust and the blade will burn it's way (rather than cut) through the wood.

Whatever blade you use, it's best to know which is the good side of the board and the blade oriented correctly. See Rehd's earlier post.
