I’ve been studying 14th century German longsword for over a year now. It’s a wonderful martial art which has help me recover some (and make gains in other areas) of my physical prowess that’s rather fallen apart with middle age and parenthood.
Recently, I learned a new guard in which you hold the sword low and in front of you, pointed off to the side. This guard, in the German tradition, is called Schrankhut (the barrier guard). See some photos here of real longsword practitioners demonstrating the guard.
