Hi Guys!

What the heck does ATB mean on a saw blade tooth profile? I am looking
for a blade to replace my OEM table saw blade (most likely the Forrest
WWII), and I keep seeing ATB as the tooth spec.

That's Alternate Top Bevel. The cutting tip of the teeth is slanted to
provide cleaner cutting for crosscuts. The slant alternates on adjacent
teeth. Frequently there is a flat top tooth interspersed to provide a
flatter bottom to the kerf. ATBR = Alternate top bevel with reker.
