Great vid.
I really like that Ethan covered the, "batoning through a knot" aspect of clubbing.
One small critique; I would have liked to see Ethan vocally address (for some of the less knowledgable folks) why he's hitting the pointy end of the blade and not the handle end of the blade.
I just mention this because sometimes we get the, "I broke my knife while batoning" thread here.
And, after some responses and pics we discover that many times those breaks have occurred because the person was clubbing the handle end of the spine.
