How does a riving knife differ from a fixed splitter?

A riving knife rises, falls and tilts with the blade.

  1. It moves up, down and tilts with the blade ✔
  2. It spins at the same speed as the blade
  3. It only works on crosscuts

Why: A splitter stays at a fixed distance behind the blade and does not rise and fall with it. A riving knife follows the blade through height and angle changes. That keeps it close to the blade for every cut depth.

Huh, didn't know that: Woodcraft says a splitter must be removed for grooves and other non-through cuts.
