I thought you might like this, as Gatts is your avatar character: From my post on the "Biology of Claymores" regarding enormous two-handed swords: "One example was wielded in medieval Germany.
"Perhaps the best known user of a Zweihänder was Pier Gerlofs Donia who is reputed to have wielded it with such skill, strength, and efficiency that he managed to behead multiple people with it in a single blow. The Zweihänder ascribed to him is, as of 2008, on display in the Frisian museum. It has a length of 213 cm (84 in) and a weight of about 6.6 kg (14½ lb)". (my candidate for the "Gatts of Beserk" Award for Swordsmen! If you think about how ridiculously large that blade is, you come to realize it is VERY possible Gatts of Beserk could've been swinging around his pre-"Dragonslayer" swords.) http://en.wikipedia.org/wiki/Zweih%C3%A4nder"
