Dao

The dao, commonly known as the “Chinese saber”, or “Chinese broadsword” when featuring a wide blade, is a single-edged and moderately curved sword designed primarily for chopping or slashing at opponents, although the curve is sufficiently moderate to allow thrusting as well. Dao handles are traditionally wrapped in cord for a firmer grip, the hilts are sometimes slanted to improve handling for some cuts and thrusts, and the guards are often disc and cup-shaped to keep rainwater out of the sheath.

Dao swords date as far back as the Shang Dynasty (circa 1600 – 1046 BC) during the Bronze Age. During the Han Dynasty (206 BC – 220 AD), the dao, by now made of iron, were in widespread use among Chinese cavalry, preferred both for its sturdiness and utility as a hacking and slashing weapon from horseback, and its simplicity and ease of use. That simplicity was perhaps the dao’s greatest asset, and ancient Chinese texts noted that it took only a week to make a new recruit proficient with a dao, compared to a month for a spear, and a year for the straight-edged jian sword.

By the middle of the Han Dynasty, daos began replacing jians as the Chinese infantry’s standard-issue sword, and by the close of the Three Kingdom Period (220 – 280), daos had completely supplanted jians in the Chinese military, relegating the jian to the personal defense weapon of the Chinese nobility and as an accouterment for ceremonial court dress.

Dao swords saw combat use as recently as WW2, when a shortage of firearms forced some Chinese soldiers and militia to fight the Japanese with daos, giving rise to “The Sword March”, a patriotic song of the era whose first line goes ”Our daos are raised over the devils’ heads! Hack them off!” As Japanese officers were commonly armed with katana swords, daos (and katanas) hold the distinction of probably being the last swords in history that were used in combat and sword vs sword duels during a war.

Falcata

Derived from Iron Age sickle-shaped knives and best known for its use by the Carthaginians during the Punic Wars against Rome, the falcata was a Celtiberian single-edged sword with a curved blade that narrowed towards the middle. It featured a hook-shaped grip made of the same piece of metal as the blade, which was often stylized in the shape of a bird or horse, with a chain connecting the hilt and the hooked butt of the grip.

The falcata design, with the blade swelling towards the tip, gave it extra mass upfront. It thus combined the speed and mobility of a sword with the cleaving or chopping power of an ax at the front. The falcata could hack off spear shafts, shatter inferior swords, and deliver tremendous blows that could split shields and helmets, The blade had the added menace of a curve that enhanced the effectiveness of the falcata’s cutting edge. The broad front tapered off into a sharp point, which rendered the sword suitable for thrusting as well.

It was one of the most devastating swords ever faced by the Romans, who first encountered it in the hands of Iberian mercenaries fighting as light infantry for Carthage during the Second Punic War, and by Iberian warriors defending their lands during the subsequent century and half of the wars fought by the Roman Republic to subdue and conquer the Iberian Peninsula. Iberian warriors wielding falcatas usually fought light, armed only with sword, small shield, and a javelin. After casting their javelins, Iberian warriors quickly closed in and sought to overwhelm their foes with speed and ferocity, employing their falcatas in combinations of slashing cuts, thrusts, and smashing overhand blows.

It was not only the quality of the falcata’s design and the ferocity of its wielders that discomfited the Romans, but also the quality of the metal that went into making it. Falcata blades were made from three layers of steel that had been buried for years in order to corrode out weaknesses, that were then joined together in a furnace. Ancient sources report that blade quality was tested by a warrior placing the flat of the blade atop his head, then bending it so handle and tip touched his shoulders. A good falcata blade was expected to spring back into shape, with no hint of the bend.

Gladius

Copied from the Celtiberians with whom the Romans first came in contact during the early stages of their conquest of Hispania, beginning in the 3rd century BC, the gladius, specifically the gladius hispaniensis, became the primary weapon of the Roman legions for the ensuing 500 or so years until it was supplanted by the spatha in the 3rd century AD. The gladius was thus the weapon that gained the Romans their empire, won their greatest victories, pushed their boundaries to their furthest extent, and brought Ancient Rome to the zenith of its power.

There was various versions of the gladius, but all gladii shared the common characteristics of being doubled-edged straight steel swords, with a blade measuring around two feet in length, tapering into a ‘V’ shaped tip and used primarily as a close quarter combat thrusting weapon, although it could be used to cut and slash as well. The handle was typically ridged for the user’s fingers or knobbed for a solid grip, and a significant feature distinguishing the gladius, its successor the spatha, and their immediate descendants into the early and intermediate Middle Ages, was the absence of a crossguard.

It was typically carried in a scabbard affixed to a belt on the legionary’s right hip. In combat, the legionary with his torso armored and his head protected by a helmet carried a long shield, initially oval, later rectangular and curved, that covered most of his body from his shins to his chin. In his right hand, he held his gladius in an underhanded grip, its tip projecting from the right side of his shield at waist level.

The legionary strove to stab his gladius into his foe’s abdomen or chest; above the upper rim of his shield into the enemy’s face or neck; or if the opportunity presented itself, slashing at the opponent’s knees or legs, or hamstringing him with a drawing cut. The gladius’ relatively short blade was an advantage in close quarters because it allowed the legionary to step inside his enemy’s guard and thrust at speed in any direction from which his foe was vulnerable – a task that would be awkward with a long sword, which would have required more space between the parties for optimal thrusting.

Spatha

In use during the Roman Empire from the 1st to 6th centuries AD, the spatha was a straight and double-edged long sword, with a blade measuring between 30 to 40 inches, that could be used single-handed or with a two-hand grip. The spatha’s name was derived from a Latin word meaning “broad sword”, and it survives to this day in Romance languages descended from Latin as the word for “sword”, such as the Italian Spada, the Spanish and Portuguese espada, the Catalan espasa, or Romanian spada.

The spatha initially reached the Roman military via Celtic cavalry auxiliaries, who used their traditional swords with blades measuring about 33 inches in length, which gave them longer reach than the standard Roman gladius to strike and slash at targets below. From Celtic cavalry auxiliaries, use of the spatha spread throughout the Roman military, and in due course, it was adopted by foot soldiers.

By the 2nd and 3rd centuries AD, the spatha had become the standard sword of Roman heavy infantry, giving them more reach when thrusting than could the gladius, which ended up being relegated to the role of sidearm of the light infantry. The cavalry version of the spatha had a rounded tip to avert the accidental stabbing of the rider’s foot or the horse’s side, while the infantry spatha had a long and sharp point suitable for thrusting.

Following its introduction to the Roman army, the spatha was enthusiastically embraced by Germanic auxiliaries, both infantry and cavalry, and from them it reached their Germanic tribes back home, where it became popular. From those Germanic tribes, the spatha became the template of early Medieval swords following the fall of the Western Roman Empire. It evolved into the Viking sword centuries later, and later still, influenced the development of the arming sword. In the Eastern Roman Empire it survived in the Byzantine army and court for centuries more, and until it finally fell in 1453, the Byzantines had a mid-level court title named spatharios, meaning “bearer of the spatha”.

Kilij

With a name derived from a Turkic root word that means “to kill”, and that appropriately sounds like its intended task even in English, the single-edged kilij was the traditional saber of the Turks and related cultures. It is a member of the family of curved swords that include the South Asian tulwar, the Afghan pulwar, and the Persian shamshir, all tracing their origins to the Turkic nomads of the Central Asian Steppe, who used them since as far back as the nomadic Xiongnu empire of the 3rd century BC.

What set the kilij apart from other members of the Turkic curved sword family was a design that added additional metal to the final foot or so of the blade, giving it more mass and weight toward the front. The additional weight near the tip shifted the kilij’s center of gravity towards the front edge, giving the blade greater momentum, and thus hacking and chopping power, at the point of likely impact, and made the kilij the best cutting sword in history. Better even than the katana at chopping things, as can be seen on various YouTube videos, including one from a Deadliest Warrior episode showing a kilij cutting the carcass of a full-grown hog in half with one swing.

Turkic curved swords were used and influenced blade designs in all lands conquered or influenced by Turkic peoples. It was a mean sounding and mean-looking sword that connoted images of mean people using them to do mean things. The ranks of famous kilij users include the Transylvanian ruler Vlad III, AKA Vlad the Impaler, who gave rise to the legend of Dracula. It was not a sword that inspired warm and fuzzy feelings.

The devastating cutting power of the kilij came at a price. It was an excellent sword for use from horseback to deliver downward strokes on infantry and was optimized for power and effective cutting. However, outside the type of combat for which it was designed, it was not an agile sword, which made it a poor weapon for dueling, especially against opponents armed with lighter swords. Faced with such opponents, an unhorsed kilij wielder would be in serious trouble if they were competent.

Saif or Scimitar

The saif, or scimitar, is a single-edged curved sword that originated in the Middle East, with early examples dating back to the 9th century Abbasid Caliphate’s Central Asian province of Khurasan. Its origins were influenced by the sabers wielded by Central Asian Turkic nomads who had recently come under the Abbasid rule and converted to Islam, and who within a few generations became the region’s true rulers.

The better specimens of saifs or scimitars were made of Damascus steel, which was derived from a high-quality crucible known as wootz steel. The blades of Damascus steel scimitars are characterized by patterns of mottling and banding reminiscent of flowing water. Unlike their cousin, the Turkish kilij, scimitars are lighter, and while they did not possess the devastating cutting power of the kilij, their lightness and agility allowed for the greater facility of use. In short, while both the kilij and saif are members of the family of curved sabers, the kilij traded speed and agility for the type of devastating cutting power that could cut an opponent in half with a single blow. By contrast, the saif eschewed such excessive power for agility and speed, rendering it useful not only for slashing from horseback, but also serviceable in dueling if its wielder was unhorsed.

As light sabers, scimitars are optimized for use from horseback by a rider slashing downwards, single-handed, at targets on foot to the left and right of his mount. They are distinguished by their thin blades, which feature little taper until towards the end of the blade, which culminates in a sharp point that renders the sword useful for thrusting, although not as effectively as straight swords that are optimized for thrusting.

In the task for which they were designed, however, scimitars were murderous. Against broken formations fleeing on foot, even a small contingent of scimitar-wielding horsemen riding into the disorganized groups could inflict devastating losses in short order. Even after infantry came to dominate the battlefield with disciplined formations that were impervious to horsemen, cavalry hovering at the edge of the battlefields, waiting for the opportunity to charge in and ride down the foot soldiers should their ranks become disorganized, were a constant menace who could at any moment transform mistakes by the infantry into massacres.

Katana

Perhaps the world’s most recognizable sword, thanks to Hollywood and TV, the katana is a single-edged curved sword, with a long handle for two-handed use that features a square or circular guard, and a slender blade usually measuring two and a half feet in length. They are among the finest cutting weapons in history, and were used by Japanese samurai since feudal times, with the earliest recorded mention in the historic record dating to the 12th century.

Katanas are the product of natural evolution, having started off as hefty “great swords” that grew thinner, lighter, and more agile over time in order to meet the demands of emerging combat styles that were increasingly reliant upon speed. They became popular with samurai because the ease and speed with which they could be drawn was a decided asset for the newer and faster-fighting styles, collectively dubbed kenjutsu, the art of sword fighting, in which the issue was often settled within seconds, and speed of reaction spelled the difference between life and death.

Katanas, coupled with a smaller sword, were thrust, sharp edge facing upwards, through the bearer’s obi – a sash wrapped tightly around the samurai’s waist – in a configuration known as daisho that identified the wearer as a samurai, and only members of that class were authorized to tote paired swords in that fashion. Wearing the katana in the daisho style facilitated a speedy draw, ideally allowing the samurai to draw and cut down his opponent in a single fluid motion, and an entire martial art, Iaido, was dedicated to the speedy retrieval of the katana from its scabbard.

Katanas are made from tamahagane steel, which is produced by traditional Japanese smelting processes that result in layered steels with varying carbon concentrations, that are welded, folded, and hammered out to reduce impurities. A katana needs a sharp and hard edge, but steel that is hard enough for a sharp edge is brittle, while softer steel that is not brittle will not take and retain a sharp edge. Katana makers solved the dilemma by using four metal bars: a soft iron bar to guard against breaking, sandwiched by two hard iron bars to prevent bending, and rounded off with a steel bar to take the cutting edge.

The four bars were heated at high temperature, then hammered into a long bar that would become the blade. Contrary to myth, samurai blades were not folded thousands or even hundreds of times – that much folding would be counterproductive and render the steel useless for a sword. When the sword was sharpened, the steel took a razor-sharp edge, while the softer iron prevented the blade from breaking. Well-crafted katanas became prized heirlooms, passed down generations of samurai families for centuries, and magnificent specimens of centuries-old katanas can be seen in the Tokugawa Art Museum in Nagoya, Japan.

Viking Sword

The Viking sword was a double-edged and relatively light straight sword that weighed between 2 to 4 pounds, thanks to a fuller running down the blade’s length that reduced weight without compromising strength. The blade, measuring between two and three feet, and 1.5 to 2.3 inches wide, was balanced by the hilt and pommel, while a slight blade taper helped bring its center of balance closer to the hilt. The grip was typically made of wood wrapped in leather, or for swords owned by the wealthy, the grip could by wrapped with gold or silver wire. By the close of the Viking era, blade lengths had increased, and some recovered samples dating back to that period had blades up to three and a half feet long. The sword’s tip was not pointed, but rounded – a rounded tip is stronger than an acute one, without being significantly less effective in piercing than a sharply pointed blade.

“Viking sword” is actually a misnomer, implying that it had been developed or used more commonly by Vikings than other peoples, when that was not the case. It was actually developed by Frankish swordsmiths in the Frankish Empire during the Carolignian era, but got its name because the most and best-preserved samples were recovered by archaeologists from Viking burial sites. By the time the swords’ true provenance had been recognized, the name “Viking sword” had already stuck, notwithstanding that “Carolignian sword” or even “Viking era sword” would have been more accurate.

Viking swords first emerged during the 8th century, having evolved from the Merovignian sword, which in turn had evolved from the Roman spatha, and were prevalent in Northern and Western Europe during the early Middle Ages. Early versions were made via pattern welding, in which iron bars of soft and hard qualities, for flexibility and strength, respectively, were combined, heated to weld them together, then twisted and drawn out in a thin strip that eventually became the blade. Later, pattern welding was abandoned after advances in metallurgy produced quality iron that could be smelted into good steel for sword blades.

In use, the Viking sword was wielded one-handed, although some historic texts mention two-handed use. However, the space on the sword’s handle between hilt and pommel, while commodious for a single-handed grip, is too small to be gripped by two hands. Some speculation posits that the texts might have meant not two hands on the handle, but one hand gripping the sword, while the other cupped the wrist of the sword hand to deliver blows with significantly more power.

Arming Sword

Developed from the Viking sword and tracing its roots back to the Roman spatha, the arming sword, also known as the knightly sword, was a double-edged straight sword with a blade usually measuring between 28 to 32 inches, although some had blades of up to 39 inches, and that featured a single-handed cruciform hilt that gave it a distinctive cross shape. It was prevalent as the main European sword from the 11th to 14th centuries, after which it was edged out by the longsword and relegated to the role of a secondary weapon or sidearm – hence the name “arming sword”.

The transition from the Roman spatha-based Viking sword to the Medieval arming sword went through the intermediate phase of the Norman sword of the 9th and 10th centuries, which witnessed a simplification of the pommel to a disk or hazelnut, and the growth of the Viking sword’s spatha handguard into a full crossguard – the main visually distinguishing feature of both the arming sword and its successor, the longsword.

By the 11th century, the transformation had been completed, and the arming or knightly sword, now featuring a more slender and tapered blade than that of the Viking sword, with a sharper tip than the more rounded one of the Viking sword, and a center of mass closer to the hilt that improved the weapon’s handling, had become the dominant state of the art European sword.

Typically used with a shield or buckler, the arming sword was an excellently balanced light and versatile weapon, useful for both thrusting and cutting. It was the main weapon of the Crusader knights, and remained the most popular sword on European battlefields throughout the late Middle Ages and into the opening stages of the Hundred Years’ War. Its heyday finally came to a close in the 14th century, which witnessed changing tactics and battlefield conditions, particularly the growing use of plate armor, against which the arming sword was of little use.

Starting in the late 12th century, arming sword designs began to polarize in reaction to the increasingly tougher armor encountered on the battlefield, becoming either longer and heavier for concussive impact and the infliction of blunt trauma through the armor, or more squat and sharply pointed to pierce the armor with a thrust. By the mid 14th century, an entirely different sword, the longsword, had emerged in response to the new armor, and proved more effective at dealing with it than the arming sword could. Thus the longsword supplanted the arming sword, and the latter was relegated to a secondary weapon or sidearm.

Longsword

The European longsword saw its heyday between the mid 14th to mid 16th centuries, during the close of the Middle Ages and into the Renaissance. Usually weighing 5 to 8 pounds, longswords are characterized, as the name indicates, by their length, with straight and double-edged blades measuring between 33 inches to four feet in length, plus long handles designed for a two-handed grip, of between 6 to 15 inches. The longsword’s other distinguishing feature is its cruciform hilt, which gave the weapon a pronounced cross shape.

Longswords were designed to deal with the emergence of increasingly tougher armor, particularly plate armor, that standard sword such as the knightly or arming swords could not deal with. In proficient hands, the longsword could defeat such armor. They first emerged in the opening stages of the Hundred Years War (1337 – 1453), and for the following two centuries they were used by knights in plate armor, whether from horseback or on foot. By the late 14th century, the longsword’s use had begun to spread to unarmored foot soldiers as well – a usage first pioneered by Swiss mercenaries.

The longsword is a cut and thrust weapon, with a light point and cutting edges designed for targets unarmored and armored. Against the latter, blows were ineffective at slicing or cutting, but could nonetheless prove telling when applied with sufficient force to deliver a concussive impact to stun and disorient the armored opponent, and leave him temporarily vulnerable to a more lethal follow up. Notwithstanding its size, in the hands of a competent user the longsword was a quick and versatile weapon that could effectively deal out lethal thrusts, slices, and cuts.

By the late 1300s, codified systems of longsword combat had emerged throughout Europe, and in its heyday, various fighting schools and fighting styles sprouted to instruct on the martial art of longsword fighting. Such schools seem to have been especially popular in Germany, which produced the most renowned longsword teachers and fight masters.

The longsword’s long handle was designed for a two-handed grip that could deliver powerful cuts and thrusts, and longsword fighting featured a variety of moves, ranging from straightforward swordplay with stabbing, hacking, and slicing, to complex martial art maneuvers that entailed wrestling, grappling, and disarmament techniques. In the hands of wielders with armored gloves protecting their hands, the longsword could also be employed in a manner known as “half-swording“, whereby the user kept one hand on the hilt and the other on the blade to deliver well-controlled and powerful jabs and thrusts. Longswords, especially those with a diamond cross-section, could penetrate plate armor with a well-applied half-sword thrust.

Lethal usage was not restricted to the longsword’s blade, and techniques were taught whereby the pronounced crossguard could be used to trip the foe or knock him off balance, to jab into the opponent’s face, or swinging the sword by the blade like a hammer, the crossguard could also be used to pierce the enemy’s helmet and skull. The pommel could also be used after a swing in a quick reverse jab to the opponent’s head or body, or more straightforwardly applied with brute force to pummel and smash in his helmet and head.

After a centuries-long heyday, changing tactics and developments ended the longsword’s battlefield utility. By the mid-1500s, projectile weapons such as crossbows whose bolts could pierce armor, and the newly introduced firearms, had come to rule the battlefield and made plate armor obsolete, and the wielders of such weapons were protected by blocks of infantry wielding pikes. Against that combination, and with the disappearance of the plate armor that had given rise to longswords, longswords ceased to offer any particular advantage. By the late 16th century, the longsword had become militarily obsolete since there was no longer a need for its power and reach on the battlefield. Thus, swords became smaller and went back to normal lengths, while longswords were relegated to sporting competitions and knightly duels.
