Some minor spoilers for Avengers Infinity War to follow. YOU. HAVE. BEEN. WARNED.
During the brawl with Thanos, Thor knew he needed a new weapon to take down the mad titan, especially after his death queen sister shattered his hammer like it was nothing (bitch). He traveled to Nidavellir with Rocket Raccoon and baby Groot to forge Thor's new weapon, the kickass hammer StormBreaker, which is usually held by Beta Ray Bill, another "Thor" who is a beast and totally badass. When they got there, the Dwarf King Eitri was reunited with his old friend, and explained that the dwarves had been rendered all but extinct and his hands had been fused off with metal as a result of Thanos's request of the forgery of the Infinity Gauntlet, which makes no sense, but, you know, plot. They make this bad Larry, and the rest is sad, sad Avengers history. Always aim for the face, Thor. Dumbass.
Without further stalling, check out what the badass Blacksmiths at Men at Arms are doing with Thor's new mega-weapon. This thing crushes a coconut that will surely make men far and wide wince in sympathy. Love watching these guys work.
