I like this idea and have requested it before. The only thing is the steel greatsword has those two flanges above the hilt that wont fit in a scabbard. The steel greatsword greatly resembles the German zweihander, which was carried across the shoulder like a pike, because they were so large and had the large crossgaurds, flanges, and grips. I would like to have multiple options of greatsword carrying. On the back, across the shoulder, and at the hip.
