When it comes to striking, what is your tool of choice? For me, I prefer an open hand strike such as a palm heel, a hammerfist or an elbow over hitting with my closed fist. IMO, you're going to run less of a chance of getting a hand injury with an open handed strike. Don't get me wrong, I am certainly not saying that a closed fist is a bad idea, just taking into consideration that it may not always be the best choice. Thoughts?
