John Wilkes Booth's Knife

When John Wilkes Booth assassinated President Abraham Lincoln on April 14, 1865, he carried a single-shot deringer pistol and a dagger. Booth used the one shot in the deringer to kill Lincoln, then attempted to fight off Major Henry Rathbone, a guest of the Lincolns in the Presidential Box, with the dagger. Booth stabbed Rathbone in the arm, nearly killing him, before jumping onto the stage and escaping.

Whether Booth used this or another dagger is uncertain, although evidence points to another.

Notice the words "Liberty" and "America," among other words, engraved in this dagger.
