Japanese Swordsmithing
Japanese swordsmithing is the labour-intensive bladesmithing process developed in Japan beginning in the sixth century for forging traditionally made bladed weapons ( ''nihonto'') including ''katana'', ''wakizashi'', '' tantō'', ''yari'', '' naginata'', ''nagamaki'', '' tachi'', '' nodachi'', '' ōdachi'', '' kodachi'', and ''ya'' (arrow). Japanese sword blades were often forged with different profiles, different blade thicknesses, and varying amounts of grind. ''Wakizashi'' and ''tantō'' were not simply scaled-down ''katana'' but were often forged without a ridge (''hira-zukuri'') or other such forms which were very rare on ''katana''. Traditional methods Steel production The steel used in sword production is known as , or "jewel steel" (''tama'' – ball or jewel, ''hagane'' – steel). ''Tamahagane'' is produced from iron sand, a source of iron ore, and mainly used to make samurai swords, such as the ''katana'', and some tools. The smelting process used is different ...

Katana (common Shema)
A is a Japanese sword characterized by a curved, single-edged blade with a circular or squared guard and long grip to accommodate two hands. Developed later than the ''tachi'', it was used by samurai in feudal Japan and worn with the edge facing upward. Since the Muromachi period, many old ''tachi'' were cut from the root and shortened, and the blade at the root was crushed and converted into a ''katana''. The specific term for ''katana'' in Japan is and the term ''katana'' (刀) often refers to single-edged swords from around the world. Etymology and loanwords The word ''katana'' first appears in Japanese in the ''Nihon Shoki'' of 720. The term is a compound of ''kata'' ("one side, one-sided") + ''na'' ("blade"),1995, (''w:Daijisen, Daijisen'') (in Japanese), w:Tōkyō, Tōkyō: w:Shogakukan, Shogakukan, , entry available onlinhere/span> in contrast to the double-sided ''Tsurugi (sword), tsurugi''.

Samurai
The samurai () were members of the warrior class in Japan. They were originally provincial warriors who came from wealthy landowning families who could afford to train their men to be mounted archers. In the 8th century AD, the imperial court downsized the national army and delegated the security of the countryside to these privately trained warriors. Eventually the samurai clans grew so powerful that they became the ''de facto'' rulers of the country. In the aftermath of the Gempei War (1180-1185), Japan formally passed into military rule with the founding of the first shogunate. The status of samurai became heredity by the mid-eleventh century. By the start of the Edo period, the shogun had disbanded the warrior-monk orders and peasant conscript system, leaving the samurai as the only men in the country permitted to carry weapons at all times. Because the Edo period was a time of peace, many samurai neglected their warrior training and focused on peacetime activities such as a ...

They run a Japanese Sword Museum in Tokyo and have a secretariat in the building. History After the Meiji Restoration and the ,search keyword "帯刀"p.18 a major concern grew that the swords would be lost overseas. Although Japanese sword making was an abandoned practice, it was revived in the 4th Imperial exhibition in 1934. The Nihonto Tanren Renshu Jo () led by Kurihara Hikosaburō discovered 82 swordsmiths from the local area and supported them. After the end of World War II, the General Headquarters of the Supreme Commander for the Allied Powers confiscated Japanese swords. However, swords that were deemed "household treasures" were excluded from the confiscation. The "Prohibition of possession of firearms" (Emperor's Decree No. 300) was promulgated, and the prohibition of "swords and valuable items as art" was excluded on June ...

Meiji Period
The was an era of Japanese history that extended from October 23, 1868, to July 30, 1912. The Meiji era was the first half of the Empire of Japan, when the Japanese people moved from being an isolated feudal society at risk of colonization by Western powers to the new paradigm of a modern, industrialized nation state and emergent great power, influenced by Western scientific, technological, philosophical, political, legal, and aesthetic ideas. As a result of such wholesale adoption of radically different ideas, the changes to Japan were profound, and affected its social structure, internal politics, economy, military, and foreign relations. The period corresponded to the reign of Emperor Meiji. It was preceded by the Keiō era and was succeeded by the Taishō era, upon the accession of Emperor Taishō. The rapid modernization during the Meiji era was not without its opponents, as the rapid changes to society caused many disaffected traditionalists from the former samu ...

Peace generally prevailed from this point on, making samurai largely redundant. Tokugawa sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bloomery
A bloomery is a type of metallurgical furnace once used widely for smelting iron from its iron oxides, oxides. The bloomery was the earliest form of smelter capable of smelting iron. Bloomeries produce a porous mass of iron and slag called a ''bloom''. The mix of slag and iron in the bloom, termed ''Direct reduced iron, sponge iron'', is usually consolidated and further forged into wrought iron. Blast furnaces, which produce pig iron, have largely superseded bloomeries. Process A bloomery consists of a wikt:pit, pit or chimney with heat-resistant walls made of earth, clay, or Rock (geology), stone. Near the bottom, one or more pipes (made of clay or metal) enter through the side walls. These pipes, called tuyeres, allow air to enter the furnace, either by natural draught or forced with bellows or a trompe. An opening at the bottom of the bloomery may be used to remove the bloom, or the bloomery can be tipped over and the bloom removed from the top. The first step taken b ...

Charcoal
Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other animal and plant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, called charcoal burning, often by forming a charcoal kiln, the heat is supplied by burning part of the starting material itself, with a limited supply of oxygen. The material can also be heated in a closed retort. Modern charcoal briquettes used for outdoor cooking may contain many other additives, e.g. coal. The early history of wood charcoal production spans ancient times, rooted in the abundance of wood in various regions. The process typically involves stacking wood billets to form a conical pile, allowing air to enter through openings at the bottom, and igniting the pile gradually. Charcoal burners, skilled professionals tasked with managing the delicate operation, often lived in isolation to tend their wood piles . Throughout histo ...

Tatara (furnace)
The is a traditional Japanese Metallurgical furnace, furnace used for smelting iron and steel. The word later also came to mean the entire building housing the furnace. The traditional steel in Japan comes from ironsand processed in a special way, called the tatara system.https://www.jsme.or.jp/tsd/ICBTT/conference02/TatsuoINOUE.html "Science of Tatara and Japanese Sword - Traditional Technology viewed from Modern Science" by Tatsuo INOUE Iron ore was used in the first steel manufacturing in Japan. Tatara steelmaking process using ironsand was conducted in the Kibi Province, which later became the base of the Japanese sword#Classification by school, Bizen school of swordsmithing, around the middle of the sixth century, and steelmaking using ironsand is thought to have spread from Kibi to various places in Japan. In western Japan, a low box-shaped furnace different from the Chinese and Korean style was used to refine iron, and in eastern Japan, both a low box-shaped furnace and a ...
