Antique Japanese Sword Katana attributed to Sadamori with
Tokubetsu Hozon
Certificate
【Description】
This blade is attributed to Reizen Sadamori, who was active during 1345-1362 (Nanbokucho period). He belonged to Kongo Hyoue (金剛兵衛), which was a prestigious school founded by Kongo Hyoue Morikuni during the late Kamakura period (around 1278) in Chikuzen province (Today’s Fukuoka prefecture). It is believed that he used Reizei (冷泉) as his title because he lived in Hakata city, which is also known as Reizentsu (冷泉津).
It is said that Kongo Hyoue had strong relationship with Sairen school, one of the most well-known schools in the region. There were quite a few renowned swordsmiths who were from this school. They resided in Urayama, where Kamado shrine, also known as Kongo Houman, was located. All the swordsmiths who belonged to Kongo Hyoue school used Mori (盛) as their maker’s name, such as Sadamori. The Nakago (tang) they created has a distinctive shape called Sotoba (卒塔婆) while this blade doesn’t have this characteristic due to Suriage (shorting the blade).
Kongo Hyoue has a strong relationship with Buddhism, as well. Those who belonged to Kongo Hyoue school exclusively forged swords for Reizan Houman Zan, a politically and militarily strong Buddhist organization at one point.
When Sadamoari was active, Japan was tumultuous because the imperial court was split into two sides(south and north). There were many conflicts, and many Samurai were deployed. And Kongo Hyoue school must have dedicated themselves to forging high-quality blades for those Samurai who fought in battles.

Kissaki

Kissaki is the tip of the Japanese sword.
Nakago
:
Nakago is the tang of the Japanese sword.
Japanese swordsmiths left the black rust on the tang because it prevents red rust while the tang is in its handle. And the discoloration of the tang was created over time, and it is a great indicator for a Japanese sword specialist to estimate when the sword was forged.
Koshirae:
Koshirae is the mounting of the Japanese sword. There are several parts that consist of Koshirae such as Saya(Scabbard), Tsuka(Handle), Tsuba(Handguard).
Fuchi-Kashira
:
A pair of matching sword fittings that cover the upper and bottom parts of its sword hilt.
The surface of this Fuchi Kashira is decorated with the Nanako-Ji (魚子地) technique. This process makes a uniform minimal protrusions pattern by hitting the Nanako-Ji Tagane (魚子地鏨, a chisel for this technique) on a metal surface. This decorative technique is often seen on sword mountings.
This Fuchi Kashira and the Menuki, both have the same animal motif: dragon. The entire appearance of this handle part has unity thanks to this combination. Among dragon-designed metal fittings, we often find dragons who bring a ball-shaped object in their hands based on our experience. This item is the Nyoi Houju (如意宝珠, Cintāmaṇi), a fantasy jewel that fulfills any desire and gives out treasure, clothes, food, and drinks. Moreover, it heals illness and suffering, removes evils, purifies muddy water, and prevents disasters. It is said this magical item is taken from the brain of the dragon king. In this way, dragons are cherished for their auspiciousness.
