厳物造太刀 Ika-Monozukuri Tachi

What is Ika-Monozukuri Tachi in Japanese Katana terminology?

Ika-Monozukuri Tachi, also known as Ika no Atama, refers to the general term for the Tachi Koshirae (sword fittings) of actual combat weapons used in the Kamakura period, characterized by flashy decorations and grand construction. The Hyogo Kusari no Tachi (兵庫鎖太刀) is a representative example. Due to the overly flashy engravings on the Fuchiwa and Ashikanamono, there were prohibitions and restrictions on wearing them during the Kamakura period.
