I'm looking for a Weapon sheath mod that gives you the option to sheath duel wield weapons on back, and a 2 handed weapon like a long-sword on your sword or hip like the default 1 handed weapons.

Also does any one know any mods that allows you to block with duel handed weapons?

Ok so read the instructions very carefully, there is a lot of things you have to do in order to get this to work, but I assure you it's worth it, I'm using this combo in my play through, it's very stable and I have no problems with it.

http://skyrim.nexusmods.com/mods/34155//? This link for the dual sheaths, check what compatible patches you need if you use weapon mods.

http://skyrim.nexusmods.com/mods/34950//? This link for the weapons on back and animations for the off hand sheathing. The animations only work in 3rd person but they look professional.

Oh and, read the instructions. Read what the requirements are and then read the instructions again. If it doesn't work for you, you did something wrong, or you have a mod that isn't compatible with it.

And the left-hand sheathes do not work with custom weapons unless you have the patch to make them work.

I forgot about that when I made some mods to craft weapons of new materials and my left hand sheath disappeared!

Then I realised my folly...

It is incredibly difficult to make dual sheath redux to work properly. You need to do many things...I do not recommend it if you're new to modding and just look to throw a mod into the game and hope it works.
