What Is The Yokote?

Yokote, in Japanese it literally means "a horizontal hand". It's the result when forging the Kissaki.

The yokote is the small line that marks the start of the blade tip (Kissaki). It acts as a line of separation between the katana blade’s body and the tip of the blade. The Yokote is the point where the tip of the blade essentially begins. It’s a signature feature of the Shinogi Zukuri katana.  Yokote katana
