The black-teal lacquer finish is achieved through layered application of urushi-style lacquer, building up depth across multiple coats rather than a single surface coat. This layering causes the color to shift visually - appearing closer to matte black under dim light and revealing its teal undertones under direct or angled illumination. The effect is significantly richer than a single-tone finish and is one reason this colorway is particularly valued for display purposes. Hand-painted saya variants in this collection add a further dimension with floral motifs applied directly into the lacquer surface, making each scabbard a one-of-a-kind decorative object in its own right.
