The bastard sword occupies an awkward place in medieval weapon terminology, which is partly why it remains so interesting. Longer in the grip than the conventional one-handed arming sword but generally less extreme than the dedicated two-handed swords of the Renaissance, it could be controlled with either one or two hands depending on the weapon, situation and fighting technique.
Today, bastard sword and hand-and-a-half sword are frequently used for this broad family of weapons. The terminology is less tidy historically. Medieval and Renaissance armouries did not operate with the neat classifications beloved by modern collectors, museums and role-playing games.
Surviving examples show considerable variation. A hand-and-a-half sword dated to around 1400–1430 in the Metropolitan Museum of Art measures 124.8 cm overall and weighs 1.56 kg, while a British or French example associated with the Castillon group from around 1450 weighs only 1.33 kg. These were substantial weapons, but certainly not the lumbering iron bars sometimes presented in films and games.
Bastard Sword Specifications
There was no medieval manufacturing standard for a “bastard sword”. Dimensions varied according to period, region and intended use. Surviving hand-and-a-half swords provide a better guide than attempting to impose a single modern definition.
| Feature | Typical Characteristics |
|---|---|
| Overall length | Roughly 110–130 cm, although larger examples exist |
| Blade length | Commonly around 90–100 cm |
| Weight | Frequently around 1.3–1.8 kg |
| Blade | Straight and double-edged |
| Profile | Broad cutting blades or more strongly tapered thrusting forms |
| Grip | Longer than a conventional one-handed sword grip |
| Pommel | Wheel, scent-stopper and other regional forms |
| Guard | Usually a substantial crossguard, with increasingly complex forms in later examples |
| Primary use | Cutting, thrusting, binding and close combat |
| Period most associated with type | Late 14th to 16th centuries |
The variation is worth stressing. The Met has a German sword from around 1500–1525 measuring 127.6 cm and weighing 1.81 kg, but an early 16th-century German or Swiss example is only 118.1 cm long and weighs 1.39 kg.
Construction
A typical weapon combined:
- A forged steel, double-edged blade
- A longer grip allowing the second hand to assist
- A wooden grip core covered with leather, cord or another material
- A crossguard protecting the hands and assisting certain close-combat techniques
- A substantial pommel helping bring the sword’s balance closer to the hand
- A blade designed for some combination of cutting and thrusting
Fullers occur on some examples, while others use strongly tapering blade sections suited to delivering accurate thrusts.
The sword was therefore not simply an arming sword with a longer handle. Its proportions could be designed around two-handed control from the beginning.
What Does “Bastard Sword” Actually Mean?
This is where things become less convenient.
Modern writing often presents the bastard sword as a clearly defined medieval weapon category sitting neatly between the arming sword and longsword. Historical terminology was far less consistent.
“Bastard sword” could describe a weapon that did not fit comfortably into established categories. “Hand-and-a-half sword” is a useful modern descriptive term, but it should not be treated as though every medieval armourer was working from the same classification chart.
Likewise, longsword and bastard sword overlap considerably in modern usage. Depending on the historian, collector, museum or HEMA practitioner involved, the same weapon might reasonably be described as a longsword or hand-and-a-half sword.
The safest definition is practical: a bastard sword is a relatively long European sword with a grip that permits effective two-handed use while retaining proportions that can allow one-handed handling.
Even that comes with exceptions. Medieval swords are annoyingly resistant to modern filing systems.
History and Evolution of the Bastard Sword
Origins in the Late Middle Ages
The development of longer grips and blades was part of a broader transformation in European arms during the 13th and 14th centuries.
Armour was improving. Mail was increasingly supplemented by plates, while full plate armour developed during the 14th and 15th centuries. Sword design changed alongside it.
Simply delivering a harder cut was not a reliable answer to good plate armour. Swordsmanship increasingly emphasised:
- Thrusting towards vulnerable areas
- Greater point control
- Blade binding
- Wrestling at close range
- Half-swording
- Use of the guard and pommel as offensive tools
Longer grips gave the swordsman considerably more leverage and control.
The 15th-Century Sword
By the 15th century, hand-and-a-half swords were established across Western and Central Europe.
The Castillon group is particularly useful evidence. Swords recovered from the River Dordogne and traditionally associated with the Battle of Castillon in 1453 include several forms characteristic of the period. The Met’s example, dated to around 1450, retains unusually extensive remains of its original grip.
Another Met sword from around 1400–1430 demonstrates how specialised some blades had become. Its stiff, sharply pointed blade is interpreted by the museum as primarily intended for thrusting and suitable for attacking armour.
The familiar medieval sword had not disappeared, but it was becoming increasingly specialised.
Into the 16th Century
The hand-and-a-half sword survived well into the Renaissance.
German, Swiss, Italian and Spanish examples demonstrate that the basic concept continued even as increasingly sophisticated guards and specialised civilian swords appeared.
The Met, for example, holds:
- A German hand-and-a-half sword from around 1500–1525
- A Swiss example from around 1525
- A Spanish example from around 1540
- A German Saxon example from around 1600
- A Solingen sword dated 1621
This makes the bastard sword difficult to confine to a single narrow historical moment. It belongs to the transition from the medieval knightly sword towards the increasingly specialised weapons of Renaissance Europe.
How the Bastard Sword Was Used
The extended grip is the defining practical advantage.
With two hands on the hilt, the swordsman gained leverage, point control and authority in the bind. The weapon could still retain enough compactness to be more versatile than the enormous two-handed swords that developed during the 16th century.
Cutting
Broad-bladed examples remained capable cutting weapons.
Two-handed leverage could produce powerful blows, but historical swordsmanship was not simply about swinging harder. Efficient cuts relied on distance, timing, blade alignment and control.
Thrusting
Thrusting became particularly important against increasingly sophisticated armour.
A sword was not expected to punch casually through a breastplate. Instead, the point could be directed towards vulnerable locations such as:
- Visor openings
- Armpits
- Groin
- Inside the elbow
- Back of the knee
- Gaps around the neck
- Other openings between plates
Half-Swording
In armoured combat the swordsman could place one hand on the blade, effectively turning the weapon into a short spear-like lever.
This allowed much finer control of the point when trying to find openings in armour.
Grabbing a sharp sword blade sounds like an excellent way to ruin your afternoon, but controlled handling of a stationary blade is very different from allowing an edge to slide through the hand.
Close Combat
The entire weapon could become useful once combat collapsed into grappling distance.
The pommel and crossguard could strike. The sword could provide leverage for throws and controls. German fighting traditions also preserve the Mordschlag or “murder stroke”, in which the sword is held by the blade and the hilt used offensively.
At that point the sword starts behaving suspiciously like a steel war hammer.
Advantages of the Bastard Sword
| Advantage | Why It Mattered |
| Two-handed leverage | Improved control during strikes, thrusts and blade engagements |
| Reach | Generally offered greater reach than an arming sword |
| Versatility | Could cut, thrust, bind, grapple and half-sword |
| Point control | Particularly useful when targeting armour gaps |
| Balance | Considerably more agile than its size may suggest |
| Close-combat options | Guard and pommel could become offensive tools |
| Flexible handling | Some examples could be manipulated one-handed when necessary |
The real attraction was adaptability. A well-designed hand-and-a-half sword could perform several jobs without becoming excessively specialised towards one.
Disadvantages of the Bastard Sword
No sword solves every problem, regardless of what fantasy games have spent several decades telling us.
- Two-handed use sacrifices a shield: A swordsman using the weapon conventionally with both hands could not simultaneously carry a large shield.
- Limited against plate: A sword remained a relatively poor tool for physically defeating plate armour compared with a poleaxe or war hammer.
- Greater size: Carrying and drawing a longer sword could be less convenient than using a shorter sidearm.
- Training requirement: Its versatility rewarded sophisticated technique.
- Less reach than polearms: Spears, bills and poleaxes could dominate distance.
- Compromise design: A versatile sword might not equal a specialist weapon at that specialist’s particular job.
This last point is important. The bastard sword’s strength was breadth of capability rather than magical superiority.
Bastard Sword vs Longsword vs Arming Sword
| Weapon | Typical Grip | Approx. Length | Typical Strength | Principal Limitation |
| Arming sword | One hand | 90–110 cm | Compact, excellent with shield | Less leverage and reach |
| Bastard sword | Hand-and-a-half / two hands | 110–130 cm | Versatility | Terminology and function overlap with longsword |
| Longsword | Primarily two-handed | 110–140+ cm | Reach, leverage and technical versatility | Occupies both hands |
| Greatsword | Two hands | 140–180+ cm | Reach and powerful battlefield use | Large and relatively cumbersome |
| Estoc | One or two hands | Variable | Strong thrusting performance | Poor or limited cutting ability |
| Falchion | Usually one hand | 80–100 cm | Powerful cutting | Usually shorter reach |
These measurements are broad approximations rather than hard categories.
Bastard Sword vs Longsword
The distinction is particularly fuzzy.
In modern HEMA terminology, many swords historically described as hand-and-a-half weapons would simply fall within the broader longsword family.
It is therefore better to think in terms of overlapping weapon types rather than imagining two entirely separate species of sword.
Bastard Sword vs Arming Sword
The distinction is clearer.
An arming sword normally has a grip intended for one hand. The bastard sword extends the grip and generally the overall dimensions, making effective two-handed manipulation possible.
The arming sword remains more naturally suited to use alongside a shield.
Bastard Sword vs Greatsword
True two-handed greatswords developed into much larger weapons, particularly during the 16th century.
A bastard sword remained fundamentally wearable as a personal sidearm. A large Renaissance two-hander could approach the proportions of a polearm.
The Bastard Sword and Plate Armour
One of the most persistent misconceptions is that medieval swords were designed to cut straight through plate armour.
They generally were not.
Against a fully armoured opponent, the sword could instead be used to control, thrust, wrestle and strike vulnerable locations. A stiff point was considerably more useful than repeatedly hitting a breastplate with the edge.
The Met’s circa 1400–1430 German example illustrates this development particularly well. Its stiff and sharply tapering blade is explicitly associated with thrusting against armour.
Against lightly armoured opponents, however, cutting remained entirely relevant.
The same broad family of weapon could therefore behave quite differently depending upon who was standing at the other end of it.
Decline and Evolution
The bastard sword did not suddenly disappear when firearms arrived.
Sword development instead fragmented into increasingly specialised forms.
During the 16th and 17th centuries:
- Civilian swords became increasingly important
- Rapiers developed around sophisticated thrust-oriented fencing systems
- Military side swords remained common
- Large two-handed swords acquired specialised battlefield roles
- Firearms increasingly shaped infantry warfare
- Polearms remained formidable against armoured opponents
Hand-and-a-half swords nevertheless continued to exist. The Met’s dated Solingen example from 1621 is a useful reminder that weapon types rarely obey the clean chronological boundaries we give them afterwards.
Legacy of the Bastard Sword
The bastard sword has had an unusually successful second life.
HEMA practitioners reconstruct longsword systems preserved in German and Italian martial traditions, bringing techniques such as winding, half-swording, grappling and close-range hilt work back into practical study.
Its influence on popular culture is even larger.
The hand-and-a-half sword has become something close to the default fantasy hero’s weapon. It is long enough to look impressive but not so large that the character appears to be carrying a sharpened railway sleeper.
That visual language appears repeatedly across fantasy games, films and television.
The historical reality is arguably more interesting. These swords were carefully proportioned fighting tools developed within sophisticated European martial traditions.
Where to See Original Bastard Swords
Several major collections hold excellent examples.
The Metropolitan Museum of Art, New York
The Met has one of the strongest readily accessible groups, including examples from the 15th, 16th and early 17th centuries. Several are displayed in its Arms and Armor galleries.
The Wallace Collection, London
The Wallace Collection contains an exceptional collection of European arms and armour, including late medieval and Renaissance swords.
Royal Armouries, Leeds
For a UK reader, the Royal Armouries is one of the obvious places to study the development of European swords alongside the armour and other weapons they were intended to confront.
European Armouries
Major collections in Germany, Switzerland, Italy, Austria and France contain further hand-and-a-half swords. Regional collections are particularly valuable because the category covers a surprisingly diverse range of blade and hilt forms.
Bastard Sword Collector’s Guide
Original medieval swords occupy a difficult corner of the arms and armour market.
Genuine examples are scarce, condition varies enormously, and substantial sums of money are involved. Attribution can also change as scholarship develops.
What Original Bastard Swords Cost
Auction values vary enormously according to date, maker, condition, provenance, blade markings, completeness and historical importance.
A useful documented example appeared at Bonhams: a fine South German hand-and-a-half sword from the third quarter of the 16th century, associated with the Munich bladesmith Melchior Diefstetter, carried an estimate of £6,000 to £8,000.
| Market Level | Indicative Price | What You Might Encounter |
| Modern decorative replica | £100–£300 | Display-oriented reproduction |
| Functional reproduction | £250–£800 | Usable modern sword of varying historical accuracy |
| Premium reproduction | £800–£2,000+ | Higher-quality historically informed construction |
| Antique sword of related later type | £1,500–£5,000+ | Considerable variation in age and authenticity |
| Genuine hand-and-a-half sword | £5,000–£15,000+ | Authenticity and condition become crucial |
| Fine named or well-provenanced example | £15,000–£50,000+ | Quality, rarity and provenance heavily influence price |
| Exceptional museum-quality sword | Potentially far higher | Major provenance or exceptional rarity can transform valuation |
These should be treated as broad collecting bands, not formal valuations. Medieval sword prices are too dependent upon individual objects for a universal price guide.
What Drives Auction Value?
The most important factors include:
- Authenticity: A genuinely medieval blade is obviously worth considerably more than a later reproduction.
- Originality: Original grip components, guards and pommels can be extremely significant.
- Condition: Corrosion is expected, but severe material loss affects desirability.
- Maker’s marks: Identifiable workshops and bladesmiths can command premiums.
- Provenance: A documented collecting history substantially improves confidence.
- Rarity: Unusual hilt or blade forms may attract specialist competition.
- Decoration: Inscriptions, inlays and high-status fittings can significantly affect value.
- Historical association: Secure association with a person, armoury or important collection can transform a sword’s market position.
How to Identify an Authentic Bastard Sword
Buying medieval arms based on photographs alone is risky.
Collectors should examine the whole object rather than searching for a single supposedly decisive sign.
Look Closely At
- Blade profile and cross-section
- Tang construction
- Pommel attachment
- Guard construction
- Corrosion patterns
- Tool marks
- Blade inscriptions
- Maker’s marks
- Grip materials
- Evidence of later restoration
- Provenance and previous auction records
Be particularly suspicious of swords that look almost too perfectly “medieval”.
Artificial ageing, assembled composite swords and older blades fitted with later hilts all exist on the market.
A Note on Pattern Welding
Pattern welding should not be treated as a standard authentication feature of a late medieval bastard sword.
By the period most strongly associated with hand-and-a-half swords, European blades were generally being produced using different methods from the conspicuous pattern-welded constructions associated with many earlier Migration-period and Viking Age weapons.
Seeing “pattern welding” advertised as proof that a supposed 15th-century bastard sword is authentic should therefore inspire questions rather than confidence.
Buying an Original Bastard Sword
For serious purchases, provenance matters almost as much as the sword itself.
Before bidding:
- Request a full condition report
- Check whether the blade and hilt are considered contemporary with one another
- Research previous auction appearances
- Examine published parallels
- Ask whether restoration has been identified
- Compare maker’s marks with recognised references
- Establish the object’s ownership history
- Factor buyer’s premium and taxes into the final price
- Seek independent specialist advice for expensive purchases
A £10,000 sword that turns out to have a Victorian blade is a particularly educational way of discovering why due diligence matters.
Modern Bastard Sword Reproductions
Collectors interested primarily in sword handling rather than antique ownership have a much easier route.
Modern reproductions broadly divide into three groups.
| Type | Intended Use | What to Check |
| Decorative | Display | Avoid using for cutting or sparring |
| Sharp functional reproduction | Cutting and collection | Steel, heat treatment, tang construction and balance |
| HEMA trainer | Martial arts practice | Flexibility, edge thickness, point safety and competition rules |
A good reproduction should feel controllable rather than simply heavy.
Historical examples demonstrate the point. The Met’s 15th-century hand-and-a-half sword weighs 1.62 kg, while its Castillon example weighs only 1.33 kg.
Medieval swordsmiths understood weight distribution rather better than the average fantasy prop department.
Is a Bastard Sword the Same as a Longsword?
Sometimes, depending upon the terminology being used.
There is considerable overlap between weapons described today as bastard swords, hand-and-a-half swords and longswords. Historical terminology was inconsistent, and modern classification systems inevitably impose clearer boundaries than medieval people themselves necessarily recognised.
The important characteristics are the weapon’s proportions, blade geometry, grip length and intended handling.
For collectors and historians, those physical features usually tell us more than the label.
The Bastard Sword in Perspective
The bastard sword deserves its popularity, although perhaps not for the reasons fantasy fiction usually gives us.
It was not a gigantic sword capable of smashing through armour. Nor was it simply an oversized arming sword.
The best surviving examples show a more sophisticated weapon: relatively light for their dimensions, carefully balanced and capable of cutting, thrusting, binding, grappling and highly controlled armoured fighting techniques.
Its extended grip gave the swordsman leverage without turning the weapon into a dedicated greatsword. That combination helped hand-and-a-half swords remain relevant across one of the most significant periods of change in European arms and armour.
The name may suggest a weapon that did not quite belong anywhere. In practice, that refusal to fit neatly into one category was precisely what made the design useful.
