Colin commented in a previous post on the unbendable arm that he is familiar with the concept of orenaite (the unbending arm) from both his aiki and his karate-do experience. Of course, orenaite finds expression in karate-do as well as aikido. Following are a couple of superb examples of near-magical karate skill. Watch these videos looking for the unbendable arm, particularly in the contexts of oizuki (the lunge punch) and gedanbarai (low block). Doesn't it look like he is doing aikido? It is because of his amazing timing, ma-ai sense, and unbendable arm!
