Bobby Pin (Fallout 3)

The bobby pin is used for lockpicking. It replaces the lock picks from Fallout and Fallout 2. Bobby pins are weightless, so they don't use any room in your inventory.

Locations - Fallout 3
Bobby pins can be found:
 * In merchant's inventories.
 * On the dead bodies of feral ghouls, raiders, trogs, and other enemies.
 * On tables inside intact houses across the Wasteland.
 * In first aid boxes.
 * In safes or other places where you have to pick the lock, so they will usually be replenished if 2 or 3 have been broken.
 * In some cash registers. There are several cash registers in the sub-basement of the National Archives.
 * In Amata's room during the quests Escape! and Trouble on the Homefront.
 * In ant refuse piles.
 * Directly west of Rockbreaker's Last Gas, on top of a large cliff, there's an abandoned shack. Inside the shack there are approximately 14-20 bobby pins on the bedside table near the average locked ammunition box.
 * In Calvert Mansion (Point Lookout) at least ten bobby pins can be found in wardrobes around the house.
 * In The Pitt, in the Supply Plant of the Steel Yard. There is an average locked door with 6 steel ingots inside. In front of the door, there are multiple packs with bobby pins.
