Just to clarify, I was not implying an angel blade could kill Raphael. I was just stating that there was no mention of them ever acquiring an archangel blade prior to that episode. It leads me to believe, that Dean was desperate to use anything against Raphael, which is not farfetched, as Meg was desperate to try to use an angel blade to kill hellhounds to great effect, a feat that was not proven until Meg actually did it. Castiel, in Purgatory, also attempted to smite a Leviathan, despite all logic that it won't work. And if this is indeed a regular angel blade, this is what I believe to have fallen into the ground when Raphael died (Raphael was holding it the whole time since Dean flung it to him/her), not his/her actual archangel blade.
