Here is my video:
The Ivan by Sean Karp.
This is a move that I have pulled off only 4 times in my life to my knowledge. I may have done more but I don't know. While I am using a shortsword to demonstrate it, you would normally use a broadsword. Though it could be used with a shortsword, mace, axe, Etc.
I named it after my SCA name "Ivan Ivanovitch Serebrenikov" and the fact that my good friend James Skalli (mka James Brooks) calls it "that damned sword move you do that no one else does!". To my memory it never gets more than 6" from my opponent on the return stroke.
Please excuse the mess and clothing. I'm recovering from a demo yesterday.
