Dear Mr. Amdur,
I just finished your book. Beautiful cover. Very interesting book. Lots of things to research. I also think Lovecraft rocks
On the subject of one-handed sword. Hirokaze Kobayashi visited Europe a lot. He frequently taught twoperson one-handed sword movements. Where he learned them I don't know. According to his senior students in Europe (amongst whom Yves Flon, who was at one time married to one of his daughters and stayed several times in Japan with Hirokazu Kobayashi) Kobayashi sensei always maintained he practiced the aikido from Osensei.
