God's Tear 

The most indestructible thing on the planet, behind the Jeep Cherokee XJ. Created by first making a Prince Rupert's Drop, then melting off the tail. The head of a PRD is indestructible, but any damage to its tail will shatter it; removing the tail leaves only the head, making it impossible to break.

I made a God's Tear for science, and now I've broken many hammers trying to break it.
