Daggers & Knives

Edged Weapons — Subcategory

Overview

The knife — a short single or double-edged cutting and thrusting blade — is the oldest and most universal of human tools and weapons. From the first knapped flint blade of the Stone Age to the combat knife carried by every modern soldier, knives and daggers have been universal constant across all cultures, all eras, and all social classes. Where swords were expensive prestige items, knives were carried by peasant and king alike.

The distinction between a knife (utility; one cutting edge; 7–30 cm) and a dagger (weapon; often double-edged; designed for thrusting; 15–50 cm) is cultural and contextual — many blades served both functions.
