Jury Rigging

"You possess the amazing ability to repair any item using a roughly similar item. Fix a trail carbine with a hunting rifle, a plasma defender with a laser pistol, or even power armor with metal armor. How does it work? Nobody knows…except you."

- Explanation of perk from Vault-Tec

 is a perk in Fallout: New Vegas.

Effects
The perk allows you to repair items based on category instead of type. For example, you can repair the rare Ranger Sequoia with the common .357 magnum revolver. Same goes for armor and clothing as well.

So far, there are at least 10 categories of weapons that the perk will enable repairing each other within category; Unarmed, One handed melee, Two handed melee, small inexpensive guns, high-end guns, energy weapons, heavy weapons, explosive throwers. Likewise, clothings can be used to repair each other within their category (Light, Medium, Heavy). Headwears are even less restricted; entire headwears - including apparels like eyeglasses - can be used to repair each other.

Guns are not strictly categorized by similarity, but by price. For example, a 12.7mm submachine gun cannot be repaired by other submachine guns, but by sniper rifles, automatic weapons and carbines. A short list of items that can be repaired with other, similar items, includes, but is not limited to:
