Hi is possible to make a 2 handed weapon be usable also in single hand mode? Just like deciding to equip it with one or two hands? just like is possible to load two spells of the same tipe on two hands , woudl be possible to load the same sword with two hands or one hand so to switch it's use from one to the other?

Basically a Bastard sword?
I guess a script toggled by a button or something could change the specific weapons type, from one-handed to two-handed.
If you could tie it to an unused button, like B it would be great. And make it sheathe like the weapon currently toggled.

I'm no good with scripts, maybe someone else wants to do it?

Off-Topic: OP, your cape mod with a Talos Amulet, I can't get it to work. How to make it show up?
And the Tullius Armour refuse to have a cape, even with the seperate .esp.

Yea it was done in Oblivion via scripting, not only could you switch your hold on a weapon from 2h to 1h or 1h to 2h, also you could switch your grip on some weapons, E.I hold a dagger facing downward etc etc , it was all in Unnecessary Violence 2 taking action, it had SOOOOOOOOOO much awesome stuff in it , if it don't get ported over i will kill a kitten. (i love cats)

may be someone could contact the author and check the script?

The cape works but you need to have it well installed or nothing will show , check your folder installation and be sure to have the armor fix that fix the armors of vanilla ....

Ok does anyone know if this is still possible or if is possible to equip both hands on a 1 h sword or viceversa?

The oblivion version made heavy use of the script extender, Idk if SKSE has the required functionality yet at this early date.
