If you take it off you should be able to bend it back into shape. Go slowly and keep test fitting it, as if you bend it too much back and forth to "get it right" it could break.Def
I attach by putting the whole tool in my pocket and then clipping the biner to the top of my pocket, so all you see if the top part of the biner at the far side of my pocket. Hope that makes sense.
I'm switching to one of these so hopefully this won't happen again.
