Hey Jean, that is a good question. I know there are many types of cuts. I will try to describe the best I can, nagamich 1 is reported to have a sword cut through three bodies, so I can assume this is an horizaontal abdomen cut, ninodo. To have a family style comparison cut would be most appropriate, I suppose that would do. Rio kuruma, being the ultimate test. However, what I consider a true test is th 45degree angle cut through the collar bone, ribs, sternum, and spine, okesa. As that is a natural draw and strike motion, assuming arms and hands arent viable... I suppose the other two could work if you turn the saya on its side, and you acquire the muscle memory.
