A push knife also known as a push dagger is a short knife with a "T" handle. The push knife is designed to be grasped in the hand so that the blade protrudes from the front of the fist. The push daggers were used to perforating armour or penetrating chain mail. Push daggers were issued as trench knives during World War I and World War II. The push knives are not only used for fighting that are great for cutting tasks because they have great leverage while using a small blade.
