A smartassy engineer recently came up with (Thor's Hammer) from The Avengers that's pretty much unliftable unless you've got my fingerprints! Watch the Video here: While the hammer is Thor's signature weapon, a handful of other characters have actually been able to pick it up, one way or another. Everyone's favorite Captain America in the Avengers: Age of Ultron kind of lifted it for half a sec. The comics have tons of other characters lifting it.
