If you want amazing hands this dvd is a must I think. The explaination is clear and scientific.
There are chapters explaining different grips ie german french etc, and how best to use them. The moeller technique is broken down and explained very well. Theres also a chapter on different techniques which is called secret weapons. My favourite chapter is the chop factory which explains exercises to help speed, accuracy, endurance, power, dexterity and control. There is also a cool concepts chapter and pratice advice.
My advice is get this dvd! 10 out of 10. Does exactly what its says on the front.
