I find the comment about being hit from unexpected angles an important point. Still, "hands up" still seems sensible advice for a lot of people. In part, it raises the level of awareness that a threat is there.
I agree that training to defeat a sword-wielding attacker is a low odds scenario, but also agree with the every six months estimate!
