Shishkebab (Fallout 3)

Shishkebab is a "flaming sword" that can be made from a motorcycle gas tank, a motorcycle handbrake, a lawnmower blade, and a pilot light (found in most ovens). It can be constructed with the use of proper schematics.

The Shiskebab instantly sets enemies on fire upon contact, dealing 2 damage a second for 5 seconds. Its schematics are given to the player by Vance at the end of the "blood ties" questline.

As with all fire and energy weapons, it can set off gas leaks. However, with the Shishkebab this can be caused by simply having it equipped and drawn.
