I've accumulated several stickers, strap-ons, and pieces of armor that provide buffs to the damage of my one and two handed weapons, as well as to bows and thrown weapons. It's easy to tell the latter two groups apart, but I can't tell how I'm supposed to know whether a weapon is one or two handed. When I preview them on the equip screen, they all look like they're being held in 'one hand' at the characters side, so I have no idea, other than my own intuition based on the physical size of the model in question which... doesn't seem like a good way to figure this out.
I'm sure there's an easier way to identify the difference that I'm just not spotting, so what is it?
