I've been looking for sheath mods, sure there are some, like Great sword sheaths, etc.

The two I am most interested in finding are.

A katana mod where the sheath is blade up.

A 2 handed sword mod where the sheath is on the hip like the one handed sword, or a mod that translates certain existing one handed swords into 2 handed stance via lack of shield or alternate option, possibly a UI component/new key designation. Personally I've always hated swords worn on the back, its impractical, and I dealt with enough of it in Fable.

I don't know, I've look all over for mods similar to these, to no avail.

Some other mods I've been looking for;

A Witcher 2 Saskia armor mod, I've seen ported model pictures but no actual mod for that particular armor.
