The New Orleans-style push dagger was known as the gimlet knife. The gimlet knife had a short two-inch (50 mm) blade with a "gimlet" or T-handle. It was a common weapon in the city during the 1800s and was usually slipped into a boot or concealed inside a coat sleeve or else hung on a waistcoat button by a strap attached to the knife's leather sheath. The gimlet knife was used in so many riots, fights, and murders in New Orleans that the city passed an ordinance in 1879 prohibiting anyone within city limits from selling, offering or exhibiting such a weapon for sale.
