#variable pitch

[xenonreality]

 @rctestflight  if you hold up a spoon & balance the flat part on your middle finger then press down with your thumb you create a pivot point that presses up one side of the spoon's scoop part up at a 45 degree angle.

Allowing for a new ball joint as well to be there that allows for not just variable pitch but rotation down & up.

Just so it's easier to imagine from the earlier comments.

Edit 1

It's a pressing down in the side of the flat part that pitches up & rotates the spoon up on one side. Basically a rotation & pivot together action based on geometry.
