S.T.A.R.S. Samurai Edge Pistol

1998: Racoon City
The Samurai Edge pistol was a standard for all S.T.A.R.S. members when they went to Racoon City to investigate the unusual deaths in and around Racoon City. Upon arrival, the S.T.A.R.S. team was attacked by zombies and the Samurai's Edge kept members Jill Valentine and Chris Redfield alive.

Eventually, after all of the zombies the gun had killed, the pistol soon resorted to 'curing' the zombies, but this was never covered in games since killing zombies is more fun than curing them.

Today: Warehouse 13
The gun the at the top of the list when the Living Dead Section was created. While stocked under the Pong Section, the artifact is stored in the Living Dead section...just in case.
