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.
Kremvh's Tooth is a unique machete with a unique mod named "sacrificial blade", which gives the weapon a large damage boost, additional poison and bleeding damage on a short duration, as well as a unique shape.
Unlike legendary weapon effects, it is possible to remove the sacrificial blade mod from the weapon at a workbench, and apply it to another machete. Thus, it is possible to install the mod on any legendary variant of the machete, giving the weapon the unique shape as well as extra effects. When the sacrificial blade mod is removed, Kremvh's Tooth becomes a regular machete, just with a different name.

Kremvh's Tooth is found at the bottom of Dunwich Borers down an underwater shaft in a little tunnel before the bottom of the shaft, flanked by two mini nukes and two glowing mushrooms on top of an altar.
Retrieving Kremvh's Tooth while wearing power armor may result in the power armor seemingly being trapped underwater since it is not possible to swim up while wearing it. The only way to get the power armor back is to have a follower enter the power armor and to then fast travel. The blade also appears in Fallout 76 as the Sacrafical Blade mod for normal machetes.
