Letter opener

A letter opener was a blunt knife used as a tool for cutting through paper envelopes.

In Alexis Drazen's hotel room at the Palmer campaign hotel during Day 1, there was a letter opener on a cabinet. Elizabeth Nash grabbed the knife and stabbed Alexis in the stomach with it, as revenge for him deceiving her.

During Day 7, after Jack Bauer had broken into Senator Blaine Mayer's house, he grabbed a letter opener. When Mayer entered the house, Jack threatened him with the blade and convinced him to help.
