....the pitch of the cutting flutes pulls the waste out of the cut.
What's that? Ya say that's what he said? BUt what about that decalate veneerial stuff?
Okay. You only use an upshear for cutting grooves in wood that don't go all the way through the piece but travel the length. That's called a Dado. Unless the groove is for a tenon in which case it's called a mortise which is actually a stopped dado. But I digress.....
These are cutting actions as opposed to the trimming action Bill was referring to. Then you definitely want the downshear which lets the substrate support the edge of the veneer as you cut and prevents tearing of the decalate veneer.
