Illustrations of history

I said different manual, but it is more of a "different chapter in the same book". There is a shitload of practicioners of the unarmored parts - that's what people train mostly as HEMA. "Armoured" fighting is more problematic since it often involves having to throw your opponent, or other dangerous shit. Also not many people can afford full plate / the plastic equivallent.

If you wanted to see a HEMA vs japanese martial arts, all it takes is getting two people who do each together.
