Is there any mod that make you can equip weapon without using them ?

Example : I had a beauty sword, but i my fighting style is Unarmed , but i want to use that sword on my back ( it will look so cool ) .

Equipping overhaul on nexus is the mod you want then. You can favourite an item and it will show on your character without having to actually use it.

There is a way to have your items shown on your body without them being equipped and without any need for a mod.

 

Open your SkyrimPrefs.ini file found in your documents/my games/skyrim folder, and under General put the following in and they'll pop up on your character if you fave them.

Hopefully this is what you're asking for.

If not, then a free tip never hurts anyone! XD!
