I'm a huge fan of Star Trek (Klingons especially) and I really love martial arts. At some point, I heard that there was a book on Bat'leth techniques, but apparently it's out of print and the only remaining copies are around $200, which is quite a bit to pay for a book I can't even preview. I've seen one or two videos of Bat'leth kata developed by fans, but does anyone here know if there is anything official which corresponds to the way Bat'leth fights are choreographed? According to one book, the person who made the weapon developed a fighting style similar to Tai Chi to correspond with its use. If anyone has any information, please send information my way.
