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 the proper schematics.

The Shishkebab instantly sets enemies on fire upon contact, dealing 2 damage a second for 5 seconds in addition to doing Melee damage. The perk Pyromaniac increases the Shishkebab's damage. Any (humanoid) followers can equip it.

Owning two schematics will allow you to create an upgraded version (10% durability increase) of the Shishkebab (v2), which requires the same materials. Owning three (MAX - v3) will give a 20% durability increase.

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.

Locations
One set of schematics can be obtained from Vance at the end of the Blood Ties questline.

You can also kill Vance to obtain his fully functional shishkebab.

Lucky Harith, the weapons caravaneer, sells a set of schematics.

You can find a set near a workbench in a red Brotherhood Outcast shack, to the south-west of SatCom Array NN-03d. The shack does not appear on the map, but is at the base of the hill the Array is built on.

Twenty clicks west of Megaton, you'll find this item on the corpse of a dead Raider. He's among a group, but you'll easily recognize him by the blackness of his skin.

I found it on a corpse by the outdoors movie, near the Hamilton's Hideaway entrance.

Trivia
The Shishkebab looks a lot like a crude version of Nero's Red Queen sword from Devil May Cry 4, down to being a flaming sword with a motorcycle handbrake.

Shish kebab is a Persian dish consisting of meat threaded on a skewer and grilled.

You can find all the components(minus the schematics) for the Shishkebab at Pinkertons workshop (if you don't mind a little bad karma) in the broken bow of Rivet City, you can even use the workbench on the second level (just make sure he doesn't see you take the components or use the workbench).

Appearances
Shishkebab appears only in Fallout 3.
