Kenichi Shiraki Blue 1 Damascus Yanagiba, with K&S Amboyna burl handle and bubinga saya. Both the blade and saya. Both the knife and saya come the decorative Chinagashi (blood groove) normally found on the Japanese katana.
Kenichi Shiraki is a renowned blacksmith in Sakai, his work is considered one of the best blacksmith in Sakai who is famous for his work on the perfect heat treatment of Blue steel as well as the distinct Suminagashi damacus pattern. Since many of you love Shiraki-san's work, I am putting all of the his knives under the same category for your convenience :)
