The drawing below is the illustration from 18| Nanboku-Cho Period Sword (南北朝太刀).  Please compare this drawing to the photo on the right.  It shows the similarity of the shape.  Keep in mind this illustration is the shape of a once very long that was shortened at a later time.   During the Nanboku-cho time, swordsmiths created 3, 4, or even 5 feet long blades, but later, they shortened them to approximately 2 to 2.5 feet or so.

Chogi* is pronounced: Chocho-san’s “cho” and giggle “gi.”  Chogi‘s sword style is categorized as one of the Soden Bizen.  See, 18| Nanboku-Cho Period Sword (南北朝太刀).  Chogi (長義) was a swordsmith from Bizen Den school who created swords with Soshu Den’s characteristicsTherefore, in short, called Soden Bizen (Bizen swordsmith forged Soshu Den).

 Chogi characteristics

  • Shape ———– Originally very long. It was shortened to approximately 2 to 2.5 feet.  
  • Hamon ——–Wide showy tempered line.  Mostly Nioi, but Nie shows also.  Sunagashi (砂流し brush stroke-like pattern) appears.  Notare (wavy) mixed with Gunome.  Sometimes Chogi created the double Gunome-style Hamon (connected one pair of half-circles). This shape resembles a pair of earlobes.  Therefore, it is called Chogi’s Mimigatamidare (irregular Hamon with earlobe shape).                                                                                                                  
  • Boshi ——————————— Irregular Midare and sharp turn back
  • Ji-hada —————————————— Itame (a wood grain pattern)

Aoe (青江) is pronounced “A” like apple, “o” like original, and “e” like egg.  Aoe was a swordsmith from Bittchu (備中) province, which is next to Bizen.  Therefore, the characteristics of Ko-aoe (old Aoe) and Ko-bizen (old Bizen) are similar.

Characteristic of Aoe (青江)

From the middle Kamakura period to the Nanboku-cho period was the height of the Aoe group. One of the characteristics of the Aoe sword is its Aoe-zori shape.  That is to curve a lot at the lower part. 

During the Nanboku-cho time, because the Soshu Den was the trendy style, even Bizen swordsmiths did Nie even though their main characteristic was Nioi.   However, the Bittchu group stayed with Nioi. 

The tempered area tends to be wide.  Sakasa-choji, which means inverted or backward style Choji (see the illustration above), is the Aoe’s most notable characteristic.  Also, Boshi often has pointed Hamon.  It is often said that if you see Sakasa-choji, the sword has a good chance of being from either the Aoe group or Katayama Ichimonji group.  Sumitetu (澄鉄:  black core metal shows through) is also Aoe’s characteristic.
