Larry - don't know if you are having a little fun at everyone's expense (ala HIPS) - because I recall it was Tomiki sensei who postulated (I cannot remember the exact wording) - "The whole body as a sword"). I take this to mean that although, form him, tegatana is a good starting point, training device, any point of the body can manifest "IT"
If I am correct, then Tomiki sensei's tegatana was not a rigid entity. Whether this is true for others in the Shodokan - maybe is an important question.
