Im watching this because this is the only show with good leo sword design- +_+
Also- his swords are called "ninjaken" or something like that
Katanas are more curved, leos blades (the ninjakan) are not curved in the slightest
Leos season 5/tales of the tmnt swords are katanas, every other leo sword are different types of ninjakan
His space blades is just the ninjakan made out of a different space thinks or some sh*t like that
Note: im sorry for turning why i watch the show into a rant about some cartoon blades-
