Mark, I think maybe terminology may be getting in the way. The Forrest WW-II is an ATB blade. It has a relatively steep angle on the corners which scores the edge of the cut nicely. I'm calling it a "combo" because it's perfectly well suited to both cross cutting and ripping unless the ripping is really thick and gnarly. It cuts sheet goods really clean, too, and matches the width of my scoring blade exactly for when I choose to employ it. I'm using a 48t 12" blade on my slider which is similar in performance to a 40t 10" blace.
