“generally” isn’t always thou, its also a video game. =p
The most common way is to two-hand, but 1 hand styles exists, as does two-handing 2 of them.
I don’t really need realism or anything, just 1handed katanas. =3
At least they did add it two handed only and not the contrary, as it makes more sense to use it two handed than one.
Once upon a time, I had a japanese kendo instructor, and he said, katana has not enough weight to cut an arm or neck used with one hand, so we use it with two hands.
Well, have you EVER seen any presentation, on television or games alike, of a Katana used with a shield? No? There is a good reason for that. It’s like using an epee while wilding an axe on your offhand… you savage!
No, seriously, you cant use a Katana properly with just one hand. They are made for slicing with very limited capability for stabing but not for slashing like a longsword.
