Mumei Koto Katana
Koto Yamato den katana
This lovely sword was polished by Jimmy Hayashi (who believes it to be a Ko-mihara school blade from the Nambokucho era), is in shirasaya, and has a beautiful two piece, gold foil habaki.
This is a beautiful sword and the jigane is flawless and absolutely breathtaking. There is a small opening about 4 inches down from the kissaki in the shinogi-ji area, but this is of little concern because of its location and size and also considering the age of the sword.
