Korean sword

Three Kingdoms era swords generally have a ring pommel. More elaborate swords hold images of dragons or phoenixes in the ring.

Evidence of sword production dates to the transitional Late Bronze to Early Iron Age (c. 1st century BC), with an earthenware mold for a Bronze Sword found in South Gyeongsang Province.[4]

The earliest Korean sword type is the so-called Hwandudaedo or "ring-pommel sword," prevalent during the 1st to 6th centuries. Until the 3rd century, these swords were very rare and presumably reserved for royalty. They became more attainable in the later 4th and during the 5th century, and are found in many higher class tombs of this period. Their production declined in the 6th century.

By the last third of the Three Kingdoms period (i.e. 450 AD and beyond), steel making techniques had come from China (possibly during the Northern and Southern dynasties period in China) and were also employed in Korean swordmaking by all three Korean kingdoms (Goguryeo, Baekje, and Silla). In 2013, a Chinese Character inscription was discovered on a 5th-century sword from the Geumgwanchong tomb in Gyeongju, North Gyeongsang Province. The scabbard of the sword has the inscription 尒斯智王 Yisaji-wang ("King Isaji").[5]

Long swords during the Korean Three Kingdoms period were used primarily by cavalry and commanders (who were also usually mounted), not infantry. At this time land warfare consisted mostly of spearmen and bowmen on foot, mounted archers on horseback using two-handed bows, and mounted swordsmen with twin blades. Swords were not a primary weapon for all combat but were instead used mostly for shock attacks, defensive strokes, and for close-in fighting. Blades were heavy as they were made mostly of bronze and later iron, and pommels were often knobbed and used as balances or for very close-in work. Short swords may have been used in follow-up attacks, as short sword carriers were heavily armored.

During the Goryeo dynasty, a limited number of Korean swords were exported for trade missions in Asia. It is likely that Korean swordmaking was influenced by Mongol and Chinese weapon manufacture after Goryeo's submission as a Mongol vassal after 6 Mongol invasions ending in 1259.

The Joseon period (15th to 19th centuries) is the "classical" era of Korean culture, including the creation of a national script and the suppression of Korean Buddhism in favour of Neo-Confucianism. Accompanying the neo-Confucian philosophies was an increased emphasis on the artistic, literary, and academic pursuits, while martial pursuits and training (still understood to be necessary) declined in cultural stature.

Korean swords were in production mostly for military and ceremonial use; private ownership outside of these purposes was largely restricted to members of the wealthy and/or politically influential classes, and possession by commoners often drew the suspicion of the authorities. Several types of ceremonial swords were made; among these sword types are the jingeom (dragon sword) and ingeom (tiger sword), which by tradition could be forged only at certain times. The highest grade of these, sa-ingeom (four tigers sword) and possibly the sa-jingeom (four dragons sword - none are extant) were reserved for the monarch and could only be made during a window of 2 hours every 12 years. The lower-grade swords - i-jingeom, sam-jingeom, i-ingeom, sam-ingeom (two dragons, three dragons, two tigers, three tigers) - could be made more frequently.

As only high-quality steel was considered for use in forging military swords, the quantity produced by Korean blacksmiths, even for Korea's own military, was limited (most Korean infantry used spears, tridents, and ranged weaponry such as the crossbow and composite bow, while swords were usually wielded by officers, local magistrates/deputies, and mounted soldiers). In addition, because Korean weapons manufacture was typically dedicated to the production of weapons for military/government use and under close scrutiny by government authorities, it was not uncommon for Koreans (both military personnel and civilians) to import swords, usually from Japan's renowned swordsmiths, in the event that Korean sources could not be secured.

Among the swords that were produced in Korea for use by its military and law enforcement officials include the jedok geom and bonguk geom (these refer to both a style of sword as well as a style of bladed combat). Blades were single-edged and usually between 6 ft (180 cm) long; however, certain swords of the jedok geom style could reach a length of 3–4 ft (91–122 cm) (while it is unclear as to the style of the swords of Admiral Yi Sun-shin, he is believed to have wielded swords that were almost that size).

During the Imjin War (1592-1598), under the influence of Japanese swords, Hwandos with blades with a length of 90 cm (35 in) or more appeared.

Geom (검; 劍) is the Korean word for "sword;" it is typically used of double-edged swords, but is also applied to single-edged swords. Yedo (예도; 銳刀) is the specific term for a single-edged sword.

Elements of the Korean sword include: geomjip or scabbard, most often of lacquer; hyuljo or fuller (most genuine Korean swords didn't have a fuller); hwando magi or collar; ho in or collar; kodeungi or hand guard; a ring-design pommel; tassels; a round and wide designed sword guard, or a straight lotus design.[6]

Many different types of Do and Geom exist,[7] ranging from very simple forms found in many nations, to very unique and artistic designs found solely in Korea.

• Jikdo, literally "straight sword."[8]
• Janggeom (장검; 長劍): literally "long sword."
• Jingum, literally "true sword." Typically used to signify a blade that is meant for combat, rather than for ceremonial or spiritual purposes.
• Changpogeom, a sword named after the calamus plant (changpo in Korean). The sword is designed to reflect the design of the plant, with a double sided blade tapering to a narrow tip.
• Hwandudaedo (환두대도; 環頭大刀) or "ring-pommel sword) is a type of single-edged sword used during the Three Kingdoms era.
• Geom is the generic term for "sword," but more specifically also refers to a shorter straight-blade, double-edged sword with a somewhat blunted tip which distinguishes this weapon from its Chinese counterpart, the jian. As a badge of status rather than a weapon, the Geom was often heavily decorated both on its scabbard and grip as well as with engravings and inscriptions on its blade.[9]
• Do, commonly referred to as a Hwando or "military sword," was a single-edged sword, used as a sidearm for the Korean soldier well into the 19th century. Sometimes referred to as a "short sword," relative to the larger sized two-handed Sangsoodo, its length of 24 to 34 in (61 to 86 cm) was comparable to that of the two-handed Japanese Katana which may have been the inspiration for the Ssangsoodo. Reports found in the "Book of Corrections," a Korean record of the Imjin Warum (1592–1598), state that Japanese swords taken in combat were readily pressed into service by simply trimming the length of the hilt. Forged of carbon steel the Do has a single-edged, curved blade, a sword guard, and a grip typically of wood. Earlier practice saw the Do suspended from a cord (Jul) and with a simple metal hanger which allowed the soldier to speedily discard his sheath. In later practice, the sword was suspended from a girdle or belt but retained a simple metal quick-release clip.[9]
• The Ssangsudo (쌍수도; 雙手刀) is a double-handed single-edged sword used for a limited time in the late 16th and early 17th centuries. Chinese literature and history both ascribe its adoption as a weapon on the Asian mainland to General Qi Jiguang (1528–1588) who is said to have taken Wokou pirate prisoners during his campaigns in Southern China. Qi Jiguang wrote about the sword in his manual the Record of Military Training or Lianbing Shi Ji (練兵實紀) and recommended its use as part of the defense along China's northern border. Since General Qi's other famous training manual, the Jixiao Xinshu (紀效新書), was used in the revamping of the Korean Military it followed that this weapon came highly recommended. Nor did the Koreans overlook that oversized swords had been used by Japanese soldiers during the recent conflict as well as during their own experiences with the Wakou. Intended by General Qi to be carried into combat on wagons or by individuals who drew each other's weapon, the Ssangsoodo measured an overall length of 6 ft (180 cm), 2 ft (61 cm) of which were to be the grip and another 2 ft (61 cm) forward of the handle to be sheathed in brass or copper. Undoubtedly the length and weight of the sword, and the high level of training necessary to wield it, made the sword impractical as a common part of the Korean arsenal. It is also useful to note that the Ming dynasty, which saw this weapon added to its own military, fell to Manchu invaders some 50 years later.[10]
• The Hyup Do or "spear sword" is found in Book Three, Chapter seven. Though commonly taken for a polearm after the fashion of the Japanese Naginata, the text of the Muyedobotongji relates that "the handle is about 4 ft (120 cm)....weighs about 4 lb (1.8 kg).....the illustration in this book is corrected according to the Mubiji and the Japanese Jang Do. They are the same." It is reasonable to conclude that the Hyup Do was much closer to the Japanese Nagamaki.[11]

• The *Woldo (월도; 月刀) was a bladed polearm, like its Chinese counterpart the Yaoyindao commonly decorated with a tassel or feather affixed to a prominence on the spine of the blade which assisted the person wielding the weapon with identifying the blade's center of mass. According to the Muyedobotongji, "the length of the handle is 6.4 ft (200 cm); the length of the blade is 2.8 ft (85 cm). The weight is about 3.15 lb (1.43 kg)."[12]
• Ssangdo or Ssanggeom (쌍도; 雙刀; 쌍검: 雙劍) This literally means "Twin Swords." It can vary from twin long swords or twin short swords. These techniques can also be used on horseback as 'Masang ssanggeom.' The Korean cavalry was famous for using Twin Sword techniques on horseback, while balancing on the horse with grace. Ssangyunggeom are twin swords which are carried in a single scabbard. The sheath is twice as wide because it needs room for the second sword. The sword's length varies from 3 to 4 ft (91 to 122 cm). Usually these swords were double-edged and made entirely of Iron (including the scabbard).
• Hyeopdo (협도; 俠刀) This is also a large crescent blade that is similar to the 'Pudao' but wider and thicker. A tassle is attached to the end of the blade.
• Hwando (환도): This is a single-edged short sword which was strictly used with one hand. This was a common sidearm for many soldiers during the Joseon era.
• Unggeom (웅검): This is a single-edged long sword that was used with one or two hands. This was another common side arm for many soldiers during the Joseon era.
• Samgakdo (삼각도; 三角刀): The samgakdo is a recently used terminology for swords used for mat cutting. The cross section of the sword is triangular in shape; hence the name Samgakdo (which means three-sided sword).
• For martial arts students learning sword forms or Geombeop/Geomsul, practice wood swords or mokgeom are most often used; then those made out of carbonized bamboo or Juk-do; lastly compression sponge, single or double-edged, with or without blood grooves. Modern sword and knife sparring commonly makes use of plastic blades.
• Chilseonggeom (칠성검; 七星劍): The name of this sword translates as "seven star sword" and it could be either single-edged or double-edged. It is primarily known for its use by Buddhist practitioners. Almost all of these swords had constellation engravings on the blades (usually the Big Dipper, although depiction of any 7 star cluster isn't uncommon).
• Sainchamsageom: This sword's name literally means 'Great Four Tiger Sword.' This is a ceremonial sword that is used for demon slaying and Shamanistic rituals.[13] The ingeom (Tiger Swords) were usually of the same designs but of different strengths. They were all made according to the Year, Month, Week, Day, and Hour of the Tiger.[13] Other examples include the sam-ingeom or 'Three Tiger Sword,' and the i-ingeom or 'Two Tiger Sword.'
• Samjeongdo (삼정도; 三精刀) the sword given to newly promoted Korean military generals each year by the Ministry of National Defense.
• The Seven-Branched Sword is a peculiar specimen forged in Baekje in the order of the king. There is a theory that this is a sword that was to be a gift presented to the emperor of Japan. There was no handle found for the blade nor was there a scabbard found for it while it was being excavated.
