Butch's Toothpick

Butch's Toothpick is a special Switchblade held by Butch DeLoria. If you let Butch live when escaping Vault 101, it can be obtained when you return later during the Trouble on the Homefront quest. It is roughly twice as powerful as an ordinary Switchblade, before Strength modifiers. It can be repaired with a regular switchblade. In some versions of the game he can actually be seen picking his teeth with it at the Muddy Rudder bar in Rivet City

Acquiring the Weapon
Dingoman013 23:37, 12 January 2009 (UTC) If acuracy is a problem shoot his arm with a high-power weapon until his arm is "CRIPPLED" and then quickly pick it up. This is the one quest after ANATA sends for you to return to the vault. Save first and do this AT THE END OF THE QUEST when Anata asks you to leave the vault.
 * The weapon cannot be acquired if you kill him on your escape from Vault 101. It shows up on his corpse as a regular switchblade.
 * One method for getting the switchblade is to wait until Butch shows up at the Muddy Rudder in Rivet City. Start a fight with him and then shoot the knife from his hands. Grab the knife, leave Rivet City and wait 72 hours. After three days, all hostility from Butch should be gone.
 * Another is to target the holstered blade, one shot should break it, at which point it will be forced into Butch's inventory (where you can pickpocket it). Not having injured Butch will allow you to holster your weapon, ending the fight peacefully.
