片落ち互の目風 (Kataochi Gunome Fu)
What is Kataochi Gunome Fu in Japanese Katana terminology?
Kataochi Gunome Fu refers to a blade pattern (Hamon) in Japanese swords where part of the blade pattern (Hamon) resembles ""片落ち互の目"" (Kataochi Gunome). This pattern is reminiscent of the teeth of a saw.
It is said that this blade pattern (Hamon) was initiated by ""長船景光"" (Osafune Kagemitsu), a swordsmith who was active in Bizen Province (now eastern Okayama Prefecture) in the late Kamakura period. The same pattern can also be seen in the works of ""長船兼光"" (Osafune Kanemitsu), who is of the same lineage.
The sword ""刀 銘 荘司次郎太郎藤原直勝 嘉永五年二月日越後国水原造之"" is a sword made by ""直勝"" (Naokatsu), a swordsmith who was the son-in-law of the famous Edo period swordsmith ""大慶直胤"" (Taikei Naotane). This sword is characterized by its Kataochi Gunome Fu blade pattern (Hamon). Naokatsu was skilled at making ""写し"" (swords made by imitating the original sword), and it is speculated that this sword is a copy of a sword made by Osafune Kagemitsu.
