Mjölnir… what can I do with it?

Sometimes Bethesda has weird Easter eggs… this is certainly one of them. Launching a nuke on the motel down in the skyline valley, and waiting for lightning to strike out back will sometimes net you Mjölnir, a regular looking hammer with a weight of 500lbs. It’s so stupid, but I want it. 500lbs though, what could i honestly do with it? Is there a way I could display it without it counting in my stash weight?
