Because of their small size and easy availability, Deringers sometimes had the dubious reputation of being a favored tool of assassins. The most famous Deringer used for this purpose was fired by John Wilkes Booth who assassinated United States President Abraham Lincoln at Ford's Theatre in Washington, D.C., on April 14, 1865. Booth's Deringer was unusual in that the rifling twisted counterclockwise (left-handed twist), rather than the typical clockwise twist.
