This old catalog has large crosscut saws (sold by the foot!). They all have a rounded “belly” on the business side and I’m wondering why.
My best guess, without just googling it, is that it widens the last strip of wood thus reducing snap offs.

Most friction will be from the sides of the blade rubbing against the kerf. I believe it’s just about concentrating force onto those teeth (which are essentially knives on crosscut saws, alongside chip clearing teeth).
