Sorry if I am hijacking the thread into a general wearing/drawing discussion:
Of course, a battojutsu cut with any sort of frog will reduce the hip hugging motion of your draw from center. Perhaps someone should invent a modern tactical version of the obi/hakama system.
Once you have done sash carry, you don't want to go back, is my opinion.
Though I know how to sash draw a sword in the Muso Jikiden Ryu style, I don't know how you would sash draw a kukiri. The only way that I have mastered is the standard draw from blade down to horizontal that Uncle Bill wrote up on the site, which is the exact opposite of the jikiden style, because- OWW DAMN.
Note to posterity, it is not safe to thumb a kukiri to loosen it in the scabbard, you will stab yourself on the notch thing. No serious injury thankfully.
The problem that I see with a sash carry for a kukiri, is that a sash favors twisting the blade away from your body like a blade up horizontal draw, whereas the kukiri seems to favor twisting it in toward your body with a blade down draw. Additionally, the kukiri seems to require that it hang at less than belt height in order to do so comfortably.
Idk, does anyone have info about which direction a kukiri was worn in a sash? The only solution to me seems to be to wear it blade up, and twist it away from you with an open hand in order to avoid cutting yourself. the karda scabbard seems to be good for this purpose, actually, but I don't have a low sash to test it with.
