Considered one of the best blacksmiths in the region, Yoshikazu Tanaka has been a blacksmith for over half a century. He now works with his son and an apprentice. He's a traditionalist, but he's always looking to improve his process and skills. It uses the traditional method of quenching with pine charcoal and it uses straw ash afterwards. It is a very old way of making knives. He does not use a thermometer for quenching, he manually calculates the temperature of the steel by examining its color. Tanaka-san is always looking to improve. He uses a temperature-controlled furnace for quenching, which only a few blacksmiths in the area use. He and his team only forge 30 knives a day between the three of them. For reference, some blacksmiths forge up to 100 blades in a single day. The reason he only forges thirty is that he takes his time, carefully forging at very low temperatures. At low temperatures, steel does not stretch as quickly, but it will retain the grain size of the steel much better. Stretching the grain size will make the steel brittle, which he tries to avoid.

He frequently moves the steel in and out of the furnace to check the color, then when the entire blade is a specific shade of color, he soaks the steel in water. The water temple (Mizu) is the most difficult to achieve and requires very careful handling.
