What is a Bastard Sword?

At its core, the bastard sword is a medieval weapon distinguished by its position between the standard one-handed sword and the larger two-handed sword. Key to its definition are its longer blade and a handle extended enough to accommodate either one or two hands. This dual-wielding capability is the hallmark of the bastard sword, setting it apart from its contemporaries.

Over time, various terms have been used to refer to this type of sword. It is frequently called a “one-and-a-half-handed sword,” a description that captures the possibility of wielding it with a single hand while the second hand can grip the pommel for added leverage, or with both hands fully on the hilt.

Early forms of the bastard sword were sometimes referred to as the “great sword” or “espée de guerre,” appearing as early as the 13th century. In Italy, it was known as the “spada da due mani,” highlighting its potential for two-handed use. In England and Scotland, the term “hand-and-a-half swords” was popular among nobles and wealthy warriors. The French term “épée bâtarde” also refers to this type of sword. While the modern term “hand-and-a-half sword” arose in the late 19th century, the term “bastard” was regularly used in the first half of the 20th century to describe this type.

The name “bastard sword” itself has sparked considerable discussion regarding its origins. One prominent theory suggests that the term arose from the sword’s hybrid nature; it was neither a purely one-handed sword nor a fully two-handed one. In this sense, it occupied an intermediate, or “bastard,” position within the existing typology of swords. Another possibility, supported by the French term “épée bâtarde,” is that it originally denoted a sword of uncertain or irregular origin, one that did not neatly fit into established categories based on its design or the swordsmithing traditions of specific regions like France, Spain, or Germany.

The term “bastard” in medieval times could also refer to something of mixed or ill-conceived origin, or of abnormal shape or irregular size. Some suggest it was nicknamed like that because it had “no family,” not fitting neatly into the classifications of single-hand or two-handed great swords . Regardless of the precise etymology, the name reflects the sword’s unique ability to bridge the gap between different sword types.

Origin of Bastard Swords

The bastard sword emerged in the late Middle Ages, with its development gaining momentum around the 14th century and reaching its zenith during the 15th and 16th centuries. This period coincided with significant shifts in warfare and, crucially, advancements in armor technology.

As knights and other warriors increasingly adopted more effective plate armor, traditional one-handed swords, often used in conjunction with shields, proved less effective against such defenses. The bastard sword arose as a direct response to this challenge, offering a versatile weapon capable of delivering more powerful blows and targeting the vulnerabilities in improved armor.  
Its development was not a sudden innovation but rather the culmination of a gradual evolution in European sword design. Its precursors can be traced back to earlier sword types. The Roman spatha, a long, double-edged sword used by the late Roman cavalry, laid a foundational influence. The Viking sword of the early Middle Ages, also contributed to later European sword designs. The knight’s sword of the High Middle Ages, already longer than earlier types, formed a more direct antecedent to the bastard sword.

While exhibiting some variation, generally adhered to a set of typical dimensions and design features that contributed to its unique capabilities. A typical bastard sword featured a blade length ranging from approximately 76 to 115 centimeters (around 30 to 45 inches), with an overall length between 101 and 152 centimeters (approximately 40 to 60 inches). The weight of these swords typically fell between 1.2 and 1.8 kilograms (about 2.6 to 4.0 pounds). The handle was extended compared to a one-handed sword, providing space for either one or two hands.

Blade Characteristics

The blade was typically straight and double-edged, often tapering to a sharp point. Some of them featured a distal taper, meaning they became thinner towards the tip, which aided in thrusting attacks. The cross-section of the blade could vary, including diamond or lenticular shapes. Many also incorporated a fuller or groove running along the length of the blade, which helped to reduce the overall weight without significantly compromising the sword’s strength and flexibility .

Hilt and Grip

The hilt was designed to facilitate both one-handed and two-handed use. So, longer than that of a typical one-handed but shorter than that of a fully two-handed sword. It was often wrapped in materials like leather to provide a comfortable and secure grip. A pronounced crossguard, typically straight or slightly curved, extended horizontally from the hilt, providing essential protection for the wielder’s hands during combat by preventing opposing blades from sliding down onto the hand.

The pommel served as a counterweight to the blade, contributing significantly to the sword’s balance and making it more maneuverable. The balance of the sword was crucial for its effectiveness, and despite its size, the clever weight distribution enabled remarkable maneuverability, allowing for both precise thrusts and powerful slashes.

Material used

Diffrent types of steel.

Historically, high-carbon steel was the primary material used for making bastard swords. This type of steel provided an excellent balance of strength, flexibility, and durability, essential for withstanding the rigors of combat. The hilts were typically crafted from steel or iron for the crossguard and pommel .

In modern times, the materials used for bastard swords vary depending on their intended purpose.

  • HEMA (Historical European Martial Arts) and Practice Swords: These swords are often made from high-quality spring steel, which offers flexibility and resilience during sparring and training.
  • Practical Swords: Modern practical swords, intended for use in cutting practice or stage combat, are usually made from tempered high-carbon steel.
  • Decorative Swords: Decorative bastard swords can be made from various materials, including stainless steel, which resists rust and corrosion but is not suitable for actual combat.

Usage in Combat

The primary advantage of this sword lay in its exceptional versatility in combat, allowing a skilled wielder to adapt their fighting style to a wide range of situations. This adaptability made it a favored weapon among knights, men-at-arms, and mercenaries throughout the late Middle Ages and Renaissance. One-handed techniques allowed for fast attacks and flexible defense, enabling the wielder to maintain agility and potentially use a shield in the off-hand.

Two-handed grips provided greater leverage and control, facilitating powerful blows. A particularly effective technique was half-swording, where the second hand gripped the blade itself. Complex bindings and twists were also employed to control the opponent’s weapon, creating openings for attack. The ability to seamlessly switch between different grip techniques gave the wilder a significant tactical advantage in various combat scenarios.

The bastard sword played a crucial role in the evolving dynamics of warfare, particularly in response to the increasing effectiveness of plate armor. While cutting through fully developed plate armor was generally not feasible, the bastard sword’s design, especially when used with two hands, allowed for powerful thrusts aimed at vulnerable areas such as joints or gaps between plates. The blade’s taper and often reinforced point were specifically designed to penetrate these weaker points in the armor. Even against opponents wearing mail armor, proved effective.

Bastard Sword vs. Longsword and Other Contemporaries

The relationship between the bastard sword and the longsword is a complex one, often marked by interchangeable usage and differing interpretations across historical periods and modern scholarship. In some contexts, particularly in modern usage and Historical European Martial Arts (HEMA), the terms are often used synonymously, with “longsword” frequently encompassing swords designed for both one-handed and two-handed use.

However, historical sources and some modern interpretations attempt to draw distinctions. Joseph Swetnam, in 1617, described the bastard sword as being “something shorter than a long sword, and yet longer than a short sword,” suggesting a middle ground in terms of blade length.

Compared to other medieval swords, the bastard sword occupied a distinct niche. The arming sword, or knightly sword, was primarily a one-handed weapon, often used with a shield, and typically had a shorter blade than the bastard. The greatsword was a significantly larger, two-handed weapon designed for powerful blows and requiring both hands for effective use.

The claymore, a Scottish two-handed sword, was also larger than the bastard sword, with a longer blade and hilt, emphasizing powerful, sweeping attacks. The bastard sword, with its ability to be wielded effectively with one or two hands, offered a level of versatility that these more specialized swords often lacked, positioning it as a crucial intermediary in the medieval armory.
