The shuto/tegatana/knifehand/swordhand should be done with the bone in the heel of the hand, which is just before the wrist, and regardless of bullshido, it's like those self defence videos where people smack each other with their forearms or clothesline each other and one guy goes flying. If you tense your hand properly, and have spent a long time training to strike with that part of your body, you could probably fuck someone up, but you could also just powerslam your forearm into the same place and get the same result.
