What is a Langet used for?

Question

(i know its not used for a horse!)

Answer 1

Keeps your sword from falling out when you're out dragon hunting....:-)

"A forward protrusion of the guard (on the blade side) designed to fit around the mouth of the scabbard to securely hold the sword in place when holstered"

Answer 2

1. a long thin strip of metal (usually either two or four) extending from the head of a staff weapon (such as a halberd) down a certain length of the wooden shaft, secured with nails or screws and designed to prevent splitting or breakage of the wood.

   2. in some swords, an extension of the guard located on both flats of the blade, designed to fit tightly over the mouth of a scabbard and prevent accidental unsheathing.
