This kozuka (small knife handle) features a mandarin duck carving. Mandarin ducks are a symbol of a happy couple, representing good fortune such as "marital harmony," "conjugal bliss," and "everlasting love." Because the male mandarin duck (o) and the female mandarin duck (an) are always together, they are often used for celebrations like weddings, kimonos, and family crests, and also express a wish for prosperity and descendants. Furthermore, the surface uses a decorative technique called "shakudo nanako-ji," where fine granules (nanako), resembling fish roe, are regularly carved into an alloy of copper mixed with gold. This kozuka expresses the closeness and good fortune through its design. It is a very attractive sword fitting, so please take this opportunity to acquire it.
