I've been searching the forums looking for a bug report on handwraps not working with Knife in the back. Much to my dismay I've been seeing posts saying its WAI for handwraps, saying "a monk using handwraps, is considered unarmed and not using a weapon so it doesn't apply to them." If this does turn out to be true I am going to be sorely disappointed. If a Monk's fists aren't considered weapons for the sake for that enhancement, then there should be no point to a Monk being unarmed and the feat "unarmed strikes" should be removed because "unarmed strikes" clearly states that the Monks fists are considered "LETHAL WEAPONS." I mean that is straight out of the Player's Handbook. Get your act together devs, you've thoroughly dropped the ball on this one, you're getting further and further away from the D&D basics.
