How can I tell if a weapon is one or two handed?
I am forging some new weapons for myself, but I don't want to waste my hard earned resources on a two-handed weapon. (I am proficient in one-handed battle)
The material type will not affect whether or not its one or two handed.

Finally, here are the two handed weapon types so you know which ones to avoid:
There are also Bows, which benefit from neither one handed perks and levels nor two handed perks and levels.
