As a follow-up to Elly's excellent saw blade talk, This short YouTube video shows how they are made.

This is great! Thanks!
When the tops of the teeth are being sharpened, notice that the grinding wheel rotates side to side for every other tooth; if anyone remembers different teeth shape patterns from my talk, it is probably sharpening them to an ATB tooth shape (alternate top bevel).
Elly:
Late note, I know, but thanks for the great presentation.
I liked the demos of the saw teeth vs. the saw dust.
And I didn’t recall the back-angled teeth being used especially for the radial arm saw.
Great job>
