Anatomical Distinctions

Knife

A knife typically has a single sharp edge designed mainly for cutting, slicing, or chopping. The blade’s length varies, ranging from small pocket knives to larger utility blades. Often, knives have a tang that extends into a handle made from materials like wood, bone, or metal.

Dagger

A dagger is a specialized type of knife with a pointy tip and two sharp edges, optimized for stabbing or thrusting. The blade is often symmetrical, and it may have a fuller to reduce weight without sacrificing strength. The handle is usually balanced to aid in precise control.

Sword

Swords are long-bladed weapons with a handle, designed primarily for slashing, stabbing, or thrusting. Swords can have single or double edges and vary significantly in design based on their intended use—such as cavalry swords, samurai swords, or fencing foils.
