With the overall, smaller diameter of the lock washer relative to the large ball base, if put under the ball, I could see the ball wanting to waver or rock back and forth, eventually loosening.
I can't imagine the guy who originally thought this was more effective?

I don't know if helical washers are intended to bite into their contact surfaces or not, but based on the hangnail they typically leave behind, they usually do. Strictly from a spring perspective, Bellville washers are the hot ticket. You can stack them for more spring pressure and they have the area of a flat washer.

They are cheaper than lock nuts.
split-lock nuts tend to bite material because people forget to use a flat washer underneath them and use a clamping nut that is too soft (to save money).
However, the washer is normally flat by the time the bolt is fully torqued. At this time it is equivalent to a solid flat washer, and its locking ability is nonexistent.
