Fighting Knife

A fighting knife is a knife whose blade is designed to inflict injury as effectively as possible in a close quarters physical confrontation. Historically it was conceived as a single purpose weapon for hand to hand combat, and the category includes military types such as the combat knife and the trench knife. Since the First World War, military fighting knives have increasingly become dual purpose, serving as combat weapons and as utility tools. The terms fighting knife and tactical knife are now often used interchangeably, though a tactical knife is designed principally as a utility tool rather than a weapon. Well known examples include the KA-BAR and the Fairbairn-Sykes fighting knife.
