Hello.
It works for the sword grip;)
In fact, I thought it should be taken on the shoulder from the front but it's in the back (which makes sense)! On the menu explanation image we can't see that it should be taken from the back;)
Maybe the sword should always come the right way? If people want to take it upside down they will just have to turn it over (by throwing it in the air).
I take this opportunity to find out if you would like a French translation? (it's free ;))
