Grognak's axe (Fallout 4)

Grognak's axe is a unique weapon found in Fallout 4.

Background
Based on the weapon that Grognak the Barbarian uses within the comic book series of the same name.

Characteristics
Hits cause more stagger, and targets take bleed damage. Hidden effect of less AP cost in VATS (standard medium speed weapon, i.e. Chinese Officer's Sword, gets ~3 swings at 7 agility, Grognak's gets roughly twice that).

Location
Inside Hubris Comics, in a locked display case (Advanced), behind the front desk.

Trivia

 * It can help with fighting large crowds of hostiles such as ghouls because of its stagger and bleed effects.
 * The weapon cannot be upgraded or renamed at a workbench.
