Is real rayskin (same) on a saya a sign of quality?

 Updated Mar 2026

Yes - genuine rayskin, known in Japanese as same (pronounced 'sah-may'), has been used on high-status Japanese blades for centuries, both as a handle wrap under ito cord and as a decorative saya covering. The material is the dried and calcified skin of stingray or ray species, characterized by small, rounded nodules embedded across the surface. On a saya, it provides a tactile texture that distinguishes a piece from plain lacquered wood while also adding material authenticity. Synthetic or ray-embossed leather alternatives are common at lower price points. When a product listing specifies real rayskin, that indicates the use of genuine same material - a detail that informed collectors specifically look for when evaluating display quality.
