 FACT: In the scene where Ghost Dog practices his kenjutsu (sword  technique), his sword is tucked into his sash with the curve of the  blade pointed downwards. In the majority of iaijutsu (sword drawing)  styles, the sword is tucked into the belt with the curve of the  blade pointed upward, so that the act of drawing the sword from the  scabbard (saya) can also serve as the first cut (kiri).
