The Kamakura era

Biography Yoritomo Minamoto image. I do a sword worn of hair-tweezers form sword. The early Japanese sword does last years and the figure which I do not take place of very much in the days of peace in the days of Kamakura, but the system of the military administration by the Kamakura Shogunate establishes it, and sword world becomes active. The back Toba ex-emperor installed turn Kaji and let I caught a swordmaker monthly and do 鍛刀, and a reason encouraged a making a sword to you positively when the ex-emperor oneself put a fried blade. Above all, 刀工則宗 of Bizen is famous. Awata mouth group, the 1 character group of the Bizen country of the Yamashiro country came into existence newly in this time.

As a result of having made much of utility when it is the middle in the days of Kamakura, width of the body is wide, and the difference of former width and the point width decreases and flat meat is good and follows it. The spearhead is wide, and length is jam-packed and becomes a man with a short, thick neck (there is it, neck) and simple and sturdy の character is good and appears. The production of the knife becomes active from these days, and it is often supposed an example. For the characteristic of the knife of this time, I slightly become the inner curve (it is thought that I polish it, and ridges decreased) whether there is not a curve, and, as for the stem, there are a thing without the curve and long-sleeved kimono form (feint sleeves). As a famous swordmaker of this time, Kunitomo of the Awata mouth group of Yamashiro, 則国, Kuniyoshi, Yoshimitsu, Kuniyasu, a country line, Kunitoshi Rai of the country next group (as for there being it), two characters country Shun (it merely cuts a signature character with "country Shun not "Kunitoshi Rai), Toma group country line", 手掻派 包永" of the Yamato country, 保昌派, Senju House group, Fukuoka 1 character group of the Bizen country are late a little, and there are Hajime Yoshioka letter group, 光忠 of Osafune group, the Zichang light, the blue Jiang Sadaji school of the Bicchu country.

In addition, in the Kamakura Shogunate, I invited a master craftsperson for making a sword study promotion from each place. It is said to the main swordmaker with the assistant truth, the country sect of the country denomination of the Fukuoka 1 character group, Kyoto biography, five Shindo light to descend from Tsutae Yamato from the Yamashiro country by six Awata Kuchifuji left neighboring country ropes, the Bizen country. As for five Shindo light, 沸働 きの seen in Tsutae Yamato establishes a strong style on minute soil iron of the conventional Tsutae Yamashiro tradition, and it is said in particular with the father of "the Sagami biography" virtually. Line light, Kunihiro are to the pupil, and Ecchu Norishige, the Goro, Okazaki lay priest sword Masamune are known to a pupil of the line light. One Sagami biography known as "the smell result" is "沸出来" Bizen biography.

A making a sword method of 5 countries of Yamashiro / Yamato / Bizen / Mino / Sagami is called "Tsutae Goka". For a making a sword of these 5 countries, I strengthen ground iron each, and there is an original characteristic in patterns on the sword blade and names it "Tsutae Yamashiro", "Sagami biography". In addition, there is a custom called "the Sagami biography" without saying "the Sagami biography" about the Sagami country. It is the division which the Honnami whole families whom Tsutae Goka runs in the Momoyama - Edo era, and lived by sword abrasion / judgment arranged.

The making a sword is energized by disturbances such as 2 degrees Mongolian Invasions or the collapse of the political system more in the days of Kamakura in last years. The Japanese sword of this time turns into the thing which made a figure of the Kamakura middle more daring. The width of the body becomes wider, and the difference of former width and last width decreases, and the things that a spearhead spread increase. A product of 長寸 comes out to a knife and other swords in the same way as a sword. But the point where a stack is thin in the whole is a big difference with the other times.

When it is terminal, and the best-known swordmaker, the Goro, Okazaki lay priest Masamune of Sagami can just write it from the Kamakura middle and played an active part in the ancient and modern times, it is supposed. He is known for the style that strengthened "the Sagami biography" which five Shindo light established more. I expressed "a work of 沸" of the whole ground blade that it was called sand style (I do not do it, but do it) / officer of the old Japanese armed forces (a Kin line) / 沸裂 (I am boiled and bloom) / 地景 (ちけい) / melting away (ゆばしり) / 沸映 り (I am boiled and move) by strengthening the place of bulls and bears iron that put steel together skillfully by strengthening the place of bulls and bears iron that put steel together skillfully than a conventional swordmaker. 沸荒 く in coming ages flies and bakes it and pulls remarkable "Sagami biography" and line, and I distinguish the product of the "Sagami biography" swordmaker at the same period from "the product of the mechanic in Sagami", and the brightness of small 沸 in a blade is particularly applauded. In addition, I established a gorgeous pattern on the sword blade of the conventional large disorder that brought "eyes disorder (ぐのめみだれ) of each other" into "gulf れ" (sauce) like "a work" of the ground iron being luxurious gorgeousness. The style of the sword Masamune had a great influence on the swordmaker of each place of the north and south dynasty period from Kamakura last years. There is a swordmaker called "sword Masamune ten sages" in the world. Though the most of them are pretexts of coming ages, and there are not real master and pupil relations with the sword Masamune, it is good and understands that the Sagami biography of the sword Masamune had an influence on each place.
