Jarnbjorn was the Dwarven-forged battle axe wielded by Thor long before he obtained Mjolnir.
In the 9th Century, unable to lift Mjolnir despite many attempts, Thor used Jarnbjorn as his regular weapon. With it he fought many foes on Earth, including frost giants, trolls and dragons.
Forged by Dwarves, Jarnbjorn is naturally sharper than almost any Earthly weapon, and can cut virtually anything. In addition, Jarnbjorn has a charm placed on it that makes it indestructible, and it can be used to defend against any attack, even bursts of energy like Apocalypse's optic beam. Thanks to Thor's own enchantment, Jarnbjorn can pierce the armor of Celestials or created using Celestial technology.
I have created 2 Handles for this for those that wish to wrap their own materials as apposed to having it printed in place.
