What is trench knife?

A trench knife is a type of combat knife designed for close-quarters combat. It typically has a blade that is around 6-8 inches in length and a handle with brass knuckles or knuckle duster design for enhanced grip and striking capabilities.

Trench knives were first used during World War I by soldiers fighting in the trenches, hence the name. They were designed to be used in hand-to-hand combat situations and were often used to penetrate helmets and other protective gear worn by enemy soldiers.

Trench knives have a long history and have been used by military forces around the world. They are still used today by some military units and are also popular among collectors and enthusiasts of military history.

It is important to note that trench knives are considered weapons and are illegal to carry in some jurisdictions. They should only be used in self-defense situations or for military training purposes.
