What is Yakiotoshi(焼落とし)?
- Yakiotoshi refers to a YAKIDASHI(焼出し) starting from not NAKAGO(茎) but 3 to 5 cm above HA-MACHI(刃区). This is seen in some swords made Heian to Kamakura period, especially by Ko-Bizen(古備前派) and Ko-Hoki school(古伯耆派).
- The more HAMON(刃文) a sword have, the easier a sword breaks. So by not heating Hamachi area, which is rarely used in a battle, a sword can absorb a shock.
