What Is the Crosspiece on a Sword For? Not Mainly for Catching Blades

The crosspiece serves several purposes and the one that matters most in ordinary use is the least dramatic. A thrust that meets resistance drives the hand forward along the grip, and without a stop the hand slides onto the blade, which on a sharp weapon is a serious self-inflicted injury. The bar prevents that. It also gives a surface to push against when withdrawing a blade, provides a place to hook or trap an opponent's weapon, and lets the sword be used in reverse with the crosspiece as a hammer or a hook, which medieval fighting manuals describe explicitly.

The parry-catching explanation does not survive examination of the objects:

• •The bar is narrow and covers very little of the hand
• •Surviving blades show edge damage along the whole length, not at the guard
• •Fighting manuals parry with the blade, not by catching on the cross
• •Later weapons that genuinely protect the hand enclose it entirely
• •Those developments came when unarmoured duelling made hands targets
• •Earlier fighting assumed a gauntlet, which protected the hand instead

The development follows changes in armour and in how swords were used. Early medieval weapons carry a simple straight bar. As fighting in armour developed techniques for gripping the blade itself, crosspieces lengthened and curved forward to hook an opponent's weapon or limb. Rings and side bars were added from the fifteenth century to protect a finger hooked over the cross for better control. Those additions multiplied into the enclosing baskets and cups of sixteenth and seventeenth century civilian weapons, at which point the hand was genuinely protected and the original bar had become one element in a complicated structure.

Understanding how the parts join explains both how such weapons are repaired and how modern reproductions fail. The blade continues past the guard as a narrow extension running through the crosspiece, the grip and the pommel, and the end of that extension is hammered over the pommel to lock everything in compression. Nothing is glued and nothing threads together in the older weapons. That means the assembly can be taken apart by drilling out the peened end, which is how museum pieces are examined and conserved, and it means a grip can be replaced without touching the blade. A reproduction with a thin extension or a threaded nut fails at exactly that joint.

The crosspiece is one part of an assembly and the other components matter as much. The grip is shaped and wrapped to give a secure hold with a wet or gloved hand, and its cross section is frequently oval so that the user knows the blade's orientation without looking. The pommel at the end is a counterweight balancing the blade, which moves the balance point closer to the hand and makes the weapon feel far lighter and quicker than its actual mass suggests, and it also physically secures the assembly, since the blade's extension passes through everything and is riveted over it.

The bar across a hilt principally stops the user's hand sliding onto the blade when a thrust meets resistance, and it gives something to push against, hook with and strike with. It is far too narrow to protect the hand from a blade, which is why genuinely protective hilts enclosing the hand appeared only when unarmoured duelling made hands targets. The pommel balances the weapon and holds the assembly together.
