Thanks for the reply! However I am well aware there are 2h weapons that have this animation. However as you may or may not know, the strange sword, is a 1h/2h sword, like the bastard sword, meaning you wear it like a 1 handed weapon. I did a little reading, and after a closer look, I'm pretty sure the animation it's using is actually the one that is used for the spear. I read that the messed up equip problems are because it uses the same stab animation as the spear or something. apparently you can edit some file and change this, but that is beyond my abilities. I was hoping there was a mod or some easier way to fix this.
Also worth noting, I'm almost positive now that it is not a mod issue because the sword turns up not only in native, but other mods as well, and they all have the same problem, not just the mod I was using at the time.
I realize this is a long shot, but I don't suppose you know how to fix this? Seems like a complicated problem
