Out of stock


Miyazaki Tanji watetsu B1 tsubaki 165mm is a very versatile blade. Tsubaki is a form invented by the meme Miyazaki-san, it strongly resembles a kiritsuke, but unlike the latter the tsubaki gains height as it approaches the tip.

History and curiosity

Haruki Miyazaki-san is a 35-year-old blacksmith from the Goto Islands in Nagasaki Prefecture. He decided to become a blacksmith and apprentice under Ooba-san in Fukuoka.

After 5 years of apprenticeship, he learned all the basic blacksmithing skills and returned to his home island, where he opened his own workshop. He continued to travel throughout Japan, learning and mastering new skills from other blacksmiths and cutlers during his travels.

Miyazaki works alone in his small forge, doing everything by hand. All of its knives are hand laminated, heat treated with pine charcoal and water tempered.

The blade

Made with an hon-warikomi structure, with an Aogami #1 steel core and a Tanji Watetsu steel cladding.

“Watetsu(和鉄)” is made from “Wazuku(和銑, pig iron)” or “Wako(和鋼, Japanese iron)”, which is made with the traditional “Tatara” oven. By melting it, removing the carbon, forging it, it becomes “Watetsu(和鉄)”.
He forges the Watetsu by wrapping it over and over, and makes what he calls “Tanji watetsu (鍛地和鉄)”, this gives a breathtaking finish to the blade.

Due to its water quenching, Aogami #1 steel has a hardness of 63-64 HRC, which allows this blade to be razor sharp, having the ability to retain the edge for longer.

The handle

Finally, the handle is made with a beautiful piece of dyed and stabilized cedar burl with a live edge.
