English Rondel Dagger, Circa 1350

Rondel daggers take their name from the two round disks (rondels) that form their guard (1). This one was found in London's Thames River and purchased by Jack Williams while he was visiting England in 1995. It dates from the mid-14th century. The overall length of the dagger is 12 1/2 inches. The 8 1/4 inch needle-point blade is diamond-shaped with hollow grounds. The guard and pommel are made of brass. An engraving of what looks like a nine-point star can just be made out on the blade side of the guard. The pommel has four petal-shaped segments engraved with lines. Long narrow daggers like this one are designed for thrusting, piercing, and stabbing. The thin, sharp point can fit through gaps in armor and penetrate leather or heavy fabric.

Rondel daggers were worn suspended on the right side of the belt or slung from the front of it. There is some evidence to suggest that rondel daggers were popular with the emerging middle class in the mid-15th century. Merchants and tradesmen can be seen wearing them in a painting by Girat de Roussillon circa 1448 (2).

Design and Construction

Beyond the round guard and pommel that give it its name, the rondel is a pure thrusting weapon. In cross-section the blade is diamond, lenticular, or triangular, and it is built to stab rather than cut — delivered underarm, or over the arm in a reverse grip, much like an ice pick. The long, straight blade simply does not lend itself to a slashing action. Some examples are four-edged with a cruciform profile; these are even more purely thrusting, and they foreshadow the 16th-century stiletto. The wide, spherical pommel is not merely decorative — its weight helps drive the point home.

Against Armour

Rondel daggers were made for close-quarters fighting, where a duel often came down to grappling. Their stiff, needle-point blades could puncture and burst the links of mail, and find the weaker points in plate armour — the thinner areas, the gaps, and the joints. As plate improved, a thrusting dagger like this was one of the only weapons that could still breach a fully armoured opponent. The fencing master Hans Talhoffer devoted whole sections of his 15th-century manuals to techniques for fighting with the rondel, both unarmoured and in single combat in armour.

A Knight's Side-Arm

The rondel evolved in the 14th century from the earlier knightly dagger, rising with the spread of full plate armour. By the 15th century it was the standard side-arm for knights, carried into battles such as Agincourt in 1415. At Bosworth in 1485, King Richard III took a fatal blow to the crown of the head from a pointed weapon such as a rondel dagger.
