This beautiful "JAPAN BLUE" version of SENKO-EI by Yu Kurosaki feature the sharp-pointed shape, the shining unique hammered texture, and Japanese traditional indigo-dyed (Ai-zome) beautiful blue handle and saya sheath.
The Ai-zome blue-colored handles and saya of these knives are carefully Ai (Japanese original indigo)-dyed with Japanese traditional method by skilled craftsperson on natural wood for Top Professional Use. Unfortunately the yield loss in the process to dye on the wood is currently very high, resulting in making the beautiful blue saya more valuable and priceless. In addition to the dying method, other special methods "Kanshitsu" and "Tenmoku" are used for this "AITENMOKU" series. Kanshitsu is a Japanese traditional Urushi lacquering process, and "Tenmoku" is also a traditional pottery mysteries in Janan.
