[MA] [Styles] Rough and Tumble: Possibly the most brutal unarmed martial art ever.

[acrosome]

Pretty neat. What I'd like to see in a similar vein is Tomahawk and Bowie Fighting. You could argue for various Guns specialties as secondary skills...
One problem is a lack of sources. A guy named McLemore wrote a book once, but it seems suspect to me. He based a lot of it off of European shortsword styles.
