太鼓金 Drum Metal (Monkane)
What is Taikogane (Monkane/Bunkin) in Japanese Katana terminology?
This refers to a round-shaped metal fitting placed in the middle of the ""Taikogawa"" (drum leather). Inside the circle, decorations such as family crests are applied. This metal fitting not only serves a functional purpose but also adds aesthetic value to the item it is attached to. The family crest or other designs can provide insights into the owner's lineage or status.
