The Quillon Dagger: The Knight's Sword in Miniature
Line up the daggers of the Middle Ages and one of them looks like a sword that shrank. Straight double-edged blade, a cross guard, a pommel: the same three parts as the knight's arming sword, at a third of the length. That is the quillon dagger, named for the cross guard itself, and it is the dagger most people picture when they picture a medieval one.
What a quillon dagger is
A quillon dagger is a dagger with a straight or slightly curved cross guard, the quillons, between blade and grip. The blade is usually double-edged and tapers to a stiff point, 8 to 14 inches long. The hilt follows sword construction: a tang through a grip of wood or wire-wrapped leather, capped by a pommel that is often the same shape as the pommel on the owner's sword. It appears across Europe from the 12th century and stays in use into the 16th, which makes it the longest-lived of the medieval dagger types.
The name is a modern classification. In its own time it was simply a dagger, and the reason it looked like a sword is that the same smiths made both, often as a matched pair for the same customer.
How it differs from the other medieval daggers
Rondel dagger
The rondel has round discs at both ends of the grip instead of a cross guard, and a narrow, stiff, often triangular blade built for punching through the gaps in plate armour. It is the armoured fighter's dagger of the 14th and 15th centuries. The quillon dagger is the more general-purpose tool and the earlier design.
Ballock dagger
Named for the two rounded lobes at the base of the grip, the ballock dagger has no cross guard at all and was carried by everyone from knights to farmers. Where the quillon dagger signals a sword-owning class, the ballock dagger is the everyday knife of late medieval Britain and the Low Countries.
Parrying dagger
The parrying dagger is what the quillon dagger became once the rapier arrived. Longer quillons, a side ring for the knuckles, and a role as the left-hand defence in a fencing system. If the quillon dagger is a small arming sword, the parrying dagger is a small rapier.
Why it matched the sword
A knight's dagger was the last resort in a fight and the first tool at a table, and it was worn at the hip beside the sword every day. Making the two match, same pommel, same guard style, same decoration, was partly vanity and partly practicality: one style of grip to learn, one visual set on the belt. Modern reproductions follow the same logic. A quillon dagger with a wheel pommel and a plain straight cross belongs beside an arming sword of the same style, and the pair reads as one piece of equipment rather than two.
What to look for in a modern one
Blade geometry. Double-edged, tapering evenly to the point, with a diamond or lenticular cross-section. A quillon dagger that is single-edged or has a clipped point is a different type wearing the wrong name.
Guard and pommel. The quillons should be straight or gently curved and not much wider than the hand. A large side ring or shell means you are looking at a parrying dagger.
Construction. The tang should run through the grip and be peened or capped at the pommel, the same way a sword is built, and nothing should shift when you hold the blade and move the hilt.
Steel. Ours are hand forged in 1095 high carbon or pattern-welded Damascus, the same steels as the swords they were made to match. Both want to be kept clean, dry and lightly oiled. Every current piece is in the daggers collection, and the parts, quillon, tang, pommel, fuller, are labeled on our parts of a sword diagram.
Frequently asked questions
What does quillon mean?
Quillon is the term for one arm of a sword or dagger's cross guard. A quillon dagger is a dagger that has them.
What is the difference between a quillon dagger and a rondel dagger?
The guard. A quillon dagger has a cross guard like a sword; a rondel dagger has flat discs at both ends of the grip and a narrow armour-piercing blade.
When was the quillon dagger used?
From roughly the 12th century to the 16th, across most of Europe. It is the longest-serving medieval dagger form.
How long is a quillon dagger?
Blades run about 8 to 14 inches, with an overall length of 12 to 19 inches. Longer examples shade into the short sword.
Is a quillon dagger the same as a parrying dagger?
No. The parrying dagger descends from it but adds a side ring or shell and longer quillons for use with a rapier in the 16th and 17th centuries.
