I just got one of the 12th Century Teutonic (as in, maybe 2 hours ago), and I have to agree with everything Kenton Spaulding said. I think it's an ok sword, with some things being surprisingly good and being something I would expect for swords maybe 2-3 times the price, and somethings being 'worse.' It definitely feels a bit too light. I have a shortened Albion Gaddhjalt blade, and they're both about the same length with similar POBs. However, I think the Balaur Arms sword has a linear
distal taper, and the Gaddhjalt does not, so it is stiffer and feels more powerful in hand. The Balaur Arms sword has waviness and uneven components, even though I bought the non-second version, but it does feel like it's within actual historical bounds.
I think the Balaur Arms sword is a fantastic starting point for a medium quality project sword, which is exactly what I got it for.
