The 'humps' are chip limiters. This limits the amount of material that can be grabbed whick limits the strength of the kickback. Very useful for low tooth count blades especially.
I didn't sit through much of the video. I have seen too much of this and similar injuries. If your machine has a guard, use it. If it is too awkward, replace it as John Tenyck so rightly pointed out. There are no excuses.
How about we do our emergency ward staff a favour and help them avoid PTSD by avoiding accidents through arrogance that says "It won't happen to me."
