#4 Captain America's Shield
This seems like an odd choice on our list, but it's really a miracle if you think about it. Here we have a standard round shield that you can pick up in any Renaissance fair. Yet it's made of indestructible material that can hold off bullets and even powerful energy blasts. Best of all, it's extremely light and aerodynamic, so much so that Captain America can throw it and make it bounce off a dozen targets before having it return to his hand.

And let's not forget that it's a one-of-a-kind shield. From wikipedia:
"During one of his experiments to fuse vibranium with an experimental iron alloy, MacLain falls asleep and awakens to find the experiment a success. This is due to an unknown catalyst entering the process during his slumber, and he is unable to duplicate the result. The vibranium-iron alloy mix is then poured into a mold for a tank's upper hatch to create the disc shape and painted to become Captain America's symbol."

An light, indestructible shield that can break the laws of physics? I'll take two please.
