Baseball bat

The Baseball Bat is a melee weapon found in Fallout 3, you can pick it up from your desk right before you leave the vault. A special baseball bat called the Louisville Slugger is also available in Fallout 2 as a quest reward. Damage-wise, Fallout 3's Baseball Bat is a quite powerful melee weapon for early use and helps to preserve ammunition while starting out in the Wastes, but becomes a weak weapon as you gain levels and should be replaced with something a bit more powerful like the Ripper, Power Fist or Shishkebab.
