The protonic inversal axe is a weapon in the Fallout: New Vegas add-on Old World Blues.


The protonic inversal axe is a variant of the proton axe, having a dark blue-violet blade, whitish capacitors, and a black handle. Compared to the standard proton axe, it deals increased damage and much more critical damage, in addition to being much more durable. It is a very effective melee weapon against just about any enemy, especially robots or power armor users.

The proton inversal axe has a special V.A.T.S. attack unlocked at 50 Melee Weapons skill called "Inversal Scarifier", which costs 35 AP, and deals double damage.

  • When any type of drug wears off, the blade of the axe is momentarily shifted to a yellow tone, before changing back to violet as the blur fades.

Behind the scenes

  • The technology used by this weapon appears to be similar to the electric weapons created in the Secret Vault by Vault-Tec.
  • The protonic inversal axe is based on the proton ax of Wasteland, the 1980s game which is considered to be Fallout's predecessor.


  • When HDR is off in graphical option, the blade becomes pitch black.
