It is a sort of a mixture between a tomahawk and reverse pendulum serve but having your hand below your bat rather than above.
It can be really effective because it is difficult to tell how much spin is on the ball. It is mainly sidespin but you can vary between backspin and topspin quite easily with it with just a tilt of your hand.
I don't have a name for it but perhaps a 'Punch serve' as the action is like you are punching.
