Motorcycle Handbrake (Fallout 3)

The motorcycle handbrake is one of the several scrap items that can be used in the construction of weapons using schematics. This item is used in the construction of the Shishkebab, but serves no other known purpose, except as Rock-It Launcher ammunition. They are often found next to motorcycle gas tank. Incidentally, whenever one finds the two together, one should always pick up the Handbrake first - picking up the gas tank will often cause the Handbrake to clip right through the floor.
