Just what the hell is that two-handed punch Spock, and to a lesser extent Kirk, was always using? Is that a part of any known fighting style? Would it be effective at all?
The answers to your questions are: 1) The dreaded DOUBLE AXE HANDLE! (Sometimes also used by Riker and pro wrestlers !) 2) No. 3) Not in the slightest. In fact, it actually takes almost all the strength OUT of your swing.
