Kremvh’s Tooth from Fallout 4 Best Melee Weapon

The unique weapon "Kremvh's Tooth" is a religious item tied to the semi-Lovecraftian god Ug-Qualtoth as a sacrificial knife, and a tool for the religious wars that it was likely created for use in – either before the advent of the first civilized nations, or in the darker eras after the Great War (the use of pre-War tech and formal "modern" company e-mails suggests the former). This weapon is one of a few remaining genuinely arcane artifacts left in the Fallout lore.
