The HT Great sword of war's nut and bevel edge obviousaly aren't very historical, though what about the weight/handling/flexibility?
Sometimes I like this sword and soemtimes I don't, what do you think?

Basically I think it is quite historically accurate regarding both looks and how it handles and functions. I'm not a fan of hex nut and this is my only sword with it for now, but it seems that it's structurally safe and durable.

I geusse I like that it seems to be a fair representaion of a specific sword type, though I'm not sure how much I like type XIII swords as opposed to to other types.

The nut is there to be able to swap between blunts and sharps on the same sword. It's an inexpensive way to get two decent swords in one and obviously meant for that market, if you're rich you can simply get two custom made matching peened swords for the same use.
I want a good solid peen on any sword I'd weild since I'd use it for powerful cutting, but for lighter use this should work fine as long as you inspect it for damage and make sure it's secure before use. And it's not like Tinker doesn't have swords in the line that are peened too, like the viking version.

The Talhoffer manuscript shows some pommels for duel longswords to be screwed on and replaceable with various spiked and edged variants for extra damage, so maybe it's not as ahistoric as some think. At least for duel purposes.

Yes, but there is no blunt blade for GSoW yet and I don't know if it's in Hanwei's plans to do it.
