21| Muromachi Period Sword (室町時代刀)

　　　　　　　The red circle above indicates the time we discuss in this section

The Muromachi period was a relatively peaceful and prosperous time until shortly before the “Onin-no-ran,” which occurred at the end of the Muromachi period.  Refer to Chapter 20, Muromachi Period History (室町時代歴史).   The Nanboku-cho style long swords became outdated; as a result, they were shortened.  The shortened blade is called suriage.  Overall, the Muromachi period was a declining time for sword-making.

Tachi and Katana 

Until the end of the Nanboku-cho period or the beginning of the Muromachi period, samurai wore swords suspended from their waists with the blade facing down.  When a sword was worn this way, the swordsmith inscribed his name on the side facing outward, meaning the blade is on your right when you see the inscription.  In this case, the sword is called a tachi.

During the Muromachi period, a sword was worn between the belt, with the blade facing up.   The swordsmith inscribed his name so that it faced outward when it was worn. Therefore, when you see the inscription, the cutting edge is to your left.  This is classified as a katana. 

Around the beginning of the Muromachi period, samurai started to wear a pair of swords called dai-sho (大小), meaning large and small.  The longer sword is a katana, and the shorter one is a wakizashi.  In general, a tachi is longer than a katana.  A katana is longer than a wakizashi, and a wakizashi is longer than a tanto.  Here is the order of their lengths. 

                                       Tachi   >   Katana   >   Wakizashi   >  Tanto                                  Tachi and katana differ in how they are worn, not in length.   

O-suriage ( 大磨上: Katana shortened by great length)　

How much the sword should be shortened depends on its original length and how much the owner wants it shortened.  O-suriage is a type of sword that is significantly shortened.  Once the blade is shortened by that length, the inscription of the maker’s name is cut off.  When the Hon’ami family (本阿弥家, a family of sword connoisseurs who have appraised Japanese swords for generations from the Muromachi period to today) appraises such a suriage sword, they write the make of the sword and the swordsmith’s name on the front side of the hilt, and the connoisseur’s name with his kaou (similar to a signature) on the back.  There are several levels of writing.  The level at which it should be done depends on the sword’s quality and the owner’s preference.  Below is the order of levels (high to low).

Shu-Mei (朱明 )————————————————————-name written in Vermilion  Kinpun-Mei (金粉名 )———————————————–name lacquered in gold powder  Gin-Zougan (銀象嵌 )————————————————————name inlaid in silver  Kin-Zougan (金象嵌 )————————————————————-name inlaid in gold

Sugata (姿: Shape) ——— The average length is typically two feet three to four inches (68~71cm).  The shape of the Muromachi period katana is somewhat similar to that of the Heian period tachi.  However, Muromachi katana are less grand or graceful than those from the Heian period swords.  The curvature is usually of the koshizori style.  Koshizori refers to the highest curvature being near the lower part of the blade.  The length and shape are suitable for wearing between the body and the belt.  The width and thickness are well-balanced with the size of the sword.  Small kissaki.

Hirazukuri-Wakizashi ———– Hirazukuri refers to a flat surface without a shinogi or yokote line.  Usually, it is 1 foot and 1 to 2 inches long.  No curvature.  Hirazukuri-wakizashi appeared during the Muromachi period.

Hamon (刃文: tempered line) ———————- Nioi base.  The tempered area is well balanced with the blade’s width.  Koshi-hiraita-midare is mixed with choji-midare.

• Boshi (Tempered line at Kissaki area) ————– Midare-komi, a short turn back.  See the above illustration.  Midare is an irregular wave-like pattern.
• Ji-hada (地肌: An area between the tempered line and Shinogi)- Soft look, a large wood grain pattern, Ji-utsuri (faint smoke or cloud-like effect) shows.
• Horimono (彫物：Engravings) ———- Bo-hi (single groove), Soe-hi (a thin groove alongside the main hi), Futasuji-hi (double narrow groove), Sanskrit, Tokko-tsuki ken, Tsume-tsuki Ken, name of God, and dragon.  Carvings became elaborate.
