Seven-Branched Sword, also known as the Seven-Pronged Sword, the
Seven-Branched Knife, the Seven-Pronged Spear, Nanatsusaya no Tachi in
Nihon shoki, Chiljido in Korea is a 74.9 cm long iron sword with six
branch-like protrusions along the central blade, designated one of the
National Treasures of Japan. The original sword is currently housed in
the Isonokami Shrine in Nara Prefecture of Japan and not shown to the
public. Replicas are displayed throughout the country and in South
Korea. An inscription on the side of the blade is an important source
depicting the relationships between the East Asian countries of the
period. The blade of the sword is 65.5 cm and the tang is 9.4 cm long.
There is no hole on the tang to fasten the sword with a hilt. The sword
is broken at the top of the tang. Analysis of the broken surface shows
the material of the sword is forged mild steel.
