Jarnbjorn! That's actually a pretty cool way to almost forgive Mjolnir getting crushed like grape.
Judging by a recent piece of concept art released in a teaser video for Avengers: Infinity War with Thor fighting alongside Rocket Raccoon, it doesn't look like Thor will be doing battle with his usual weapon, Mjolnir. It was recently brought to my attention that he's not wielding that weapon in the art. No, the weapon he's got in his hands is called Jarnbjorn, and it's a freakin' battle axe!
This is a weapon that Thor used in the comics when he was not worthy of Mjolnir. The battle axe was forged by the Dwarfs of Nidavellir, and it's indestructible thanks to an enchantment that was placed on it.
Jarnbjorn is naturally sharper than almost any earthly weapon and can cut virtually anything. It's also said that it can "be used to defend against any attack, even bursts of energy like Apocalypse's optic beam." Also, thanks to Thor's own enchantment with his own blood, Jarnbjorn can pierce the armor of Celestials.
