Throughout the centuries, the dagger has played a prominent role both on the battlefield and in civil, ritual, and symbolic contexts.
It is a short, double-edged blade designed for close combat and effective penetration. Its evolution has been marked by geography, culture, and function, giving rise to a variety of clearly differentiated forms.
In this article, we examine the main types of daggers according to their shape, understanding their historical, symbolic, and technical value.
Straight-bladed dagger

The straight-bladed dagger is probably the most recognizable in medieval Europe.
Its symmetrical and sharp blade allows for a precise and powerful thrust.
During the Middle Ages and the Renaissance, these daggers were used as a complement to the sword, especially in duels or as a secondary defense.
The French main gauche, used with the left hand to block or deflect attacks, and the rondel, with a round guard, are two emblematic variations of this category.

Curved-bladed dagger

This design is characteristic of regions such as the Middle East, North Africa, and Central Asia.
The curved blade favors wide and fast cuts.
A prominent example is the Arabian khanjar, which combines elegance and lethality. Its S-shaped blade and richly decorated hilt also make it a status symbol.
The Persian pesh-kabz, with a slightly curved blade and reinforced spine, was designed to penetrate mail armor, revealing its tactical effectiveness.
Triangular-bladed dagger

With a triangular or, in some cases, rhomboidal cross-section, these daggers were especially useful for piercing padded armor or leather seams.
Its narrow blade concentrates the force in a small point, causing deep wounds that are difficult to treat.
Some versions were used in trench warfare or as a weapon of last defense by officers.
Dagger with wavy blade

The Southeast Asian kris is the best-known example.
Its serpentine blade not only serves an aesthetic or symbolic function, but can also produce irregular and serious wounds.
In many Indonesian and Malaysian cultures, the kris is considered a spiritual object, blessed in rituals and passed down as a family heirloom.
The ripple can also deflect enemy blows, adding a defensive dimension.

Dagger with a short, broad blade

These daggers are similar to combat knives, with a robust design, thick blade and sharp point.
They were common in naval and colonial environments, where versatility was essential.
The Anglo-Saxon seax, although longer, represents an antecedent of these weapons, used both for cutting and stabbing.

Stiletto dagger

The Italian stiletto emerged during the Renaissance and was perfected as a concealed weapon.
Its blade is long, narrow and very pointed, specialized in the precise thrust.
Not suitable for cutting, this dagger was ideal for piercing clothing and vulnerable areas of the body.
Its design influenced many modern self-defense weapons.

Ceremonial and ritual daggers

In many cultures, the dagger has transcended its military function to become a ritual object.
Examples such as the Scottish sgian-dubh, worn in the sock during celebrations, or the Tibetan daggers used in tantric rituals, demonstrate how design also responds to the symbolic.
These daggers are often richly ornamented and loaded with spiritual or identity meaning.

Historical and cultural changes reflected in steel
The morphology of the dagger is as varied as its history. From the lethal precision of the stiletto to the ritual sweep of the kris, each type of blade responds to a specific need, whether military, ceremonial, or social.
This diversity makes the dagger one of the most versatile and symbolically significant weapons in human history.
