Muramasa (村正)

This chapter discusses the famous Muramasa (村正).  Usually, many well-known swordsmiths come from one of the Goka-den (五家伝: the five main schools: Yamashiro-den, Bizen-den, Soshu-den, Yamato-den, and Mino-den).  However, Muramasa was not from Goka-den but from Ise Province.  The first-generation Muramasa was known as a student of He’ian-jo Nagayoshi (平安城長吉) of Yamashiro-den.  The Muramasa family existed through the mid-Muromachi period.  They spanned three generations from the mid-Muromachi to the Sengoku period

Below is one of Muramasa’s tantos, made during the Sengoku period.  Since it was made during the Sengoku era, the blade shows the style of Sengoku-period swords.  It reflects Mino-den characteristics, combined with Soshu-den traits.

Characteristics  on this Tanto

Muramasa’s tantos are typically about ten inches ± half an inch or so.  Hirazukuri (平作り). Thin blades with a sharp look.  The nioi base with small nie and sunagashi patterns (brushed sand-like patterns, as shown in the illustration below) appears.  The boshi (the top part of the hamon) is jizo (a side view of a human head).  The tempered line varies with both wide and narrow areas.  Some areas are so narrow, almost close to the edge of the blade, while others are broader.  Hako midare (box-like shape) and gunome (lined-up bead pattern) appear.  O-notare (large, gentle waviness) is a signature characteristic of Muramasa.  The pointed-tempered line is a typical characteristic of Mino-den (Sanbon-sugi).  Refer to Chapter 23, Sengoku Period Sword, and Chapter 24, Sengoku Period Tanto.

20 Enbun Jyoji Kowakizashi Tanto

The drawing above shows a typical shape of a Nanboku-cho-period tanto. This drawing was in Chapter 19.  I exaggerated the features of the Enbun Joji ko-wakizashi tanto to better show you.  At the end of Chapter 19, Nanboku-cho Tanto, there is a list of swordsmiths’ names from that period.  Hiromitsu (広光) and Akihiro (秋広) represent the Nanboku-cho style.

Enbun Joji Ko-wakizashi tanto is also called Sun-nobi tanto (>10 inches) because its length is longer than the standard size (about 10 inches) tanto.  The upper part of the tanto curves outward slightly.  This type is called sakizori.

Characteristics of Hiromitsu (広光) and Akihiro (秋広)

  • Shape———————— Usually, one foot and one to two inches long (Sun-nobi).   Wide width.  Thin blade.  Sakizori.
  • Hamon ———————- A mix of wide and narrow hamon.  The hamon around the yakidashi (just above the machi) area is narrow but gradually widens as it moves up.  The hamon around the fukura area shows most work.  Mainly nie.  Sunagashi, kinsuji, gunome, umanoha-midare (horse teeth-shaped hamon), or hitatsura appear (drawing above).                 
  • Boshi———-Irregular and unevenly tempered.  The hamon covers almost the entire boshi. Deep turn back. 
  • Jihada ———————————————————Wood-grained pattern
  • Nakago —————–Tanago-bara shape.  Refer to 19 Nanboku-cho Period Tanto.

Nobukuni (Below is my sword)

Shodai Nobukuni (the first-generation Nobukuni) was a student of Sadamune.  He was one of the Sadamune San Tetsu (貞宗三哲, Sadamune’s top three students).  Nobukuni’s characteristics resembled those of Hiromitsu and Akihiro, as described above.  Nobukuni also created sun-nobi tanto.  The sword below has a hoso-suguha, ko-mokume (small burl pattern), and ko-maru boshi (small round).

0-timeline - size 24 Middle Kamakura

The red circle indicates the area we discuss in this chapter 

It is rare to find a tanto (短刀 dagger) made during the Heian period.  During the middle Kamakura period, many high-quality tanto were produced.  They were called takenoko-zori shaped tanto, with “takenoko” meaning bamboo shoot.  The back of the tanto curves inward slightly.
