[Preserved Sword] Mumei (Attributed to Kaifu) Katana – NBTHK Certificate Included
Though unsigned (mumei), this katana is certified by the NBTHK (The Society for the Preservation of Japanese Art Swords) as a work by the Kaifu school, one of the representative swordsmith groups from Awa Province (present-day Tokushima Prefecture).
The Kaifu tradition is known for balanced craftsmanship, stable forging patterns, and blades suited for both martial and aesthetic value. This sword showcases those qualities, with a graceful curvature and refined geometry. The presence of four mekugi-ana (peg holes), two of which have been filled, indicates that the sword was cherished and preserved over generations.
It is a highly valuable piece, not only for appreciation but also as a preserved and authenticated Japanese sword with historical significance.
