Kogarasu Maru

The Kogarasu Maru was designed with a curved double-edged blade approximately 62.8 cm long.

A single koshi-hi (腰樋) style groove runs from the tang to the transition point where the blade becomes double-edged, and is invariably accompanied by a soe-hi (添樋).

The hardening process yielded a straight temper line (sugaha hamon, 直刃刃文) on both sides of the blade.

Murata Tsuneyoshi, a General of the Imperial Japanese Army during the Meiji era, created the first Gunto, famously known as Murata-To which is a Kissaki Moroha Zukuri style double edged Katana.

Though rare, Kissaki Moroha Zukuri style Katanas have also been featured in Japanese novels, manga and anime.
