What is Uchizori in Japanese Katana terminology?

The term "Uchizori" (内反り) refers to a unique curvature of a Japanese sword where the blade bends towards the edge side, unlike the "Uchigatana" which typically bends towards the spine side. This distinctive feature can be observed in "Tachi" (long swords) from the Asuka to Nara periods, and in "Tanto" (short swords) from the Kamakura period. This characteristic is not only aesthetically pleasing but also functional, as it affects the sword's balance and cutting ability.
