On a side note, I edited my first thought. There seems to be a saw mill definition of the sawing process, and there is a separate description of the grain flow through a piece of board stock. My point of view is of the final blank, not the process it took to get there.

I think I've mentioned before, when I've gone after a log with a quarter sawn hope in mind. I split the piece so it follows the grain, then it's slow going clean up of wedges, shimmed through the planer, and on the band saw. I'd much rather end up with three or four nice pieces, than ten or twelve average pieces.
