The proton axe is a weapon in the Fallout: New Vegas add-on Old World Blues.
The proton axe resembles a futuristic war-axe with a glowing blue blade of electrical energy at its head. On the other side it has two capacitors which also share the same blue electric current. The proton axe does extra damage against robots and enemies with power armor. It has a special V.A.T.S. attack called "proton electrocutioner" unlocked at 50 melee weapons skill which costs 35 AP and deals double damage.
It can be repaired with the inexpensive proton throwing axe, raising its resell value drastically.
