The Moment of Yakiire quenching. Amazing transformation during Katana making.

Welcome to Samurai Tavern!
Most of you might have seen a swordsmith quenched a long straight red-hot steel into a water bath. The long straight steel then come out from the water curving upward, which is exactly the shape of a Japanese sword.
This process is called Yakiire (Ya-ki-i-re, 焼き入れ), which is carried out in order to harden the blade of the sword. It is one of the most important processes in Japanese sword making.

However, have you ever seen how a Japanese sword changes its shape during the Yakiire process?
Have you ever wondered what is happening to the sword during this process?

In this video, you will get the chance to watch a very rare footage of the Yakiire moment.
What’s more, we will explain scientifically about what happened during the Yakiire.

We hope you will enjoy this video while getting to know deeper on what is the science behind the Yakiire process.
