Well, there is 2 handed handle length wise and 2 handed handling wise. I feel like most Japan style based Busse designs would be fine used one handed, even the Gemini sword.
Gladius while shorter than viking, has a 2 hander length handle as well. Now, the extra material might add more weight to balance the blade like a historical pumel...but I never held one in hand.
The tg 19 sword, has and interesting handle design as well which gradually widens towards the pumel. So it might actually facilitate a grip which naturally slides up for more chocked up hold, and adds pummel weight making it a better 1 hander handling wise.
But that's based in looks. Only swords I got are viking and spartan on order.
Another sword to consider is the busse hognose war sword. It's yet another chopper design that isn't a kukri
