Stiletto

The Italian word "stiletto" comes from the Latin stilus, the thin pointed Roman writing instrument used to engrave wax or clay tablets in ancient times.

[10] Originally designed as a purely offensive weapon, the stiletto was used to finish off a fallen or severely wounded heavily armored opponent.

Later, the Gunner's Stiletto became a tool for clearing cannon-fuse touch holes and used in the same manner as an automotive oil dipstick, they were often inscribed with marks indicating levels of powder charges for ranging distance.

[14][15] By the time of the Renaissance, the term stiletto had come to describe a range of slender thrusting knives closely resembling the French poignard, many with conventional dagger-profile blades and sharpened edges, but always retaining the slim profile and needle-like point.

[13][17][18][19] While still used as a weapon of surprise and assassination, the use of stiletto in preference to the dagger in close combat confrontations between adversaries became widespread throughout Italy, Sardinia, and Corsica.

[21] A person skilled in the use of a stiletto would thrust the knife deep into the victim, then twist the blade sharply in various directions before retracting it, causing the sharp point to inflict severe internal damage not readily apparent when examining the entrance wound.

[22] The stiletto followed the first wave of Italian diaspora to the city of New Orleans, Louisiana during the mid-19th century, where the knife became a popular weapon of gamblers, gang members, and assorted assassins.

[26] The emergence of fierce hand-to-hand combat in the trenches of World War I created a new need for stabbing weapons, resulting in the reappearance of the dagger and the stiletto.

[29] World War II saw a resurgence of the stiletto in the form of combat knives for commando raiding forces and other troops who needed a weapon for silent killing.

[33] These Italian switchblades were commonly and popularly referred to as stilettos, since most incorporated a long, slender blade tapering to a needle-like point, together with a slim-profile handle and vestigial cross-guard.
