How can you throw a cutter?

What is the most efficient (without twisting your wrist) way to throw a cut fastball? And what exactly does it do?

I bumped it but that link will take you to it.

A cutter will move away from the batter similarly opposite to the way a 2-seam moves in to a batter. If that makes sence :lol: :smiley:

Sometimes mine drops a bit, but more side to side if anything.
