Your knuckle joints, instead of curving downwards, are often flat or are bent upwards even. Usually this is a sign of tension or a lack of effiency. If you can find a good teacher to look at what you're doing and correct your hand position I think you'll be in much better shape.

Why do that when you can just be unnecessarily cruel instead?
