Yeah when I read "the ultra sharp serrated kind" I think of the old Ginsu infomercials with the knives that could “cut through a nail, a tin can, and a radiator hose, and still cut a tomato paper thin!"

If that's what we're talking about here, sawing through stuff with those is going to mark up whatever you use. Might as well try the suggested bamboo if you want a wood board.
