This chapter is the continued part of chapter 16|The Revival of Yamato Den (大和伝復活 .   Please read chapter 16 before reading this chapter.

51 Japan map Yamato

At the end of the Kamakura period, in the Yamato area, powerful temples expanded their territory.  They had the political and military power to control the area.  Especially a few powerful temples owned a large territory.   They were called Shoen (荘園).  The demand for the Sword increased by warrior monks called Sohei (僧兵).  That started the revival of Yamato school.  Some of the big temples had their own swordsmiths within their territory.  Todaiji-temple (東大寺) backed Tegai (手掻 ) group.  Senjuin (千手院 ) group lived near Senju-Do (千手堂 ) where Senju Kannon (千手観音 ) was enshrined.  The name of the Taima group came from Taima-Ji temple (当麻寺).  Shikkake group (尻懸 ) and Hosho group (保昌 ) as well.  Those five groups are called Yamato Goha  (Yamato five groups).

General Characteristic of Yamato Den

Yamato Den (大和伝) sword always shows Masame (柾目, straight grain like) on somewhere on Ji-Hada,  Jigane or Hamon.   Please refer to the 16 Revival of Yamato Den (大和伝復活) for its general characteristic.  Masame is sometimes mixed with Mokume (burl like) or Itame (wood grain like).  Either way, Yamato sword shows Masame somewhere.  Some sword shows Masame entirely or some shows a lesser amount.  Because of that, Hamon tends to show Sunagashi (brush stroke like) or a double line like Hamon called Nijyu-ha.

  • Hamon —–Mainly  Medium Suguha.  Double Hamon.  Suguha mixed with Choji. Shows Inazuma, Kinsuji, especially under Yokote line Inazuma appears.
  • Boshi —– Often Yakizume. Refer Yakizume on 16 Revival of Yamato Den (大和伝復活)
  • Ji-Hada Ji-Tetsu —– Small wood grain and well knead surface.  At the top part of the sword, wood grain pattern becomes Masame.

 Shiikkake Group (尻懸  )

  • Boshi —– Yakizume, Hakikake (swept trace by broom) and Ko-maru ( small round)
  • Ji-Hada, Ji-Gane —– Small burl mixed with Masame.  Shikkake group sometimes shows Shikkake Hada.  That is,  Ha side shows  Masame and Mune side shows burl.

Example of Kantei process how to figure out the maker of the sword using the above photo

  • To determine Jidai (time) by Sugata (shape) —-—-Heian (possible),  Early Kamakura (possible),   Middle Kamakura (possible),  Late Kamakura (possible),  Nanboku – Cho (unlikely),  Muromachi (possibly No),   Sengoku (possibly No),  Shinto ( possibly No),  Shinshin-To (No)
  • To judge from Hamon (actual view shows Masame)——-Yamashiro-Den (possible),  Yamato-Den (very possible),  Bizen-Den (unlikely possible),  Soshu-Den (unlikely possible),  Mino- Den (No)
  • Jihada (actual view shows Nie a lot) —–Yamashiro-Den (possible),  Yamato-Den (very possible),  Shoshu-Den (unlikely possible),  Bizen-Den (unlikely ),  Mino-Den (unlikely)

By looking at the bold letter above, analyzing the above information, you conclude and come up with the name of the swordsmith.  In reality, to Kantei, bring more checkpoints and come up the name.

20 | Nanboku-Cho Tanto(南北朝短刀)

18 Nanbokucho time line

The circle indicates the time we are discussing in this section

 

During the Nanboku-Cho Period, the type of Tanto called Hirazukuri-Kowakizashi-Sunnobi-Tanto was made.  Hirazukuri means a flat sword without the Yokote line and without Shinogi.  Ko-Wakizashi means a shorter sword.  Sun-Nobi Tanto means longer than standardThis is also called Enbun Jyoji Kowakizashi Tanto.  It is called this way because the majority of this type Tanto was forged around Enbun, Jyoji Imperial era.  In Japan, each time the Emperor changed, we changed the names of the era.  Enbun was from 1356 to 1361, Jyoji was from 1362 to 1368

 

20 Enbun Jyoji Kowakizashi Tanto

Shape (Sugata 姿) ——-It is common idea that the length of Tanto should be 1 shaku or less.  Shaku is an old Japanese measurement unit, which is very close to 1 foot.  8.5 sun (old Japanese measurement unit) is approximately 10 inches. This is the standard length Tanto called Jo-Sun Tanto.  Anything longer than Jo-Sun Tanto is called Sun-Nobi Tanto.  Anything shorter than Jo-Sun is called Sun-Zumari Tanto.  Most of the Nanboku-Cho Tanto is approximately 1 foot 2 inches long, therefore they are called Hirazukuri-Kowakizashi-Sun-Nobi Tanto Sakizori (curved outward at the top.  See the illustration above).  Wide width and thin body.  Fukura Kareru (No Fukura). Shin-no-Mune.  See the illustration below.
