Kogarasu Maru – Double Edge Katana sword
Kogarasu Maru – Double Edge Katana sword
The Kogarasu Maru – a double-edged Katana – is also called the Little Crow. It is a distinct Japanese Katana believed to have been crafted by Amakuni.
Known as a legendary smith, it is said that Amakuni made Kogarasu Maru in the 8th century CE. The sword was also said to be a double-edged Katana.
Currently, the Kogarasu Maru can be found with the Japanese Imperial Collection. Its Tang is not signed like other classic swords, but the blade is claimed to have been created in the early Heian period. It was also possible to have been made in the late Nara period.
There are two other Kogarasu Zukuri that exists from the period. However, there are other similar types of blades crafted throughout history.

What is the Original Version of Kogarasu Maru?
The original version of this blade appeared like a European broadsword or Chinese Jian. The sword had one side sharpened, while the other side only had its tip sharpened the same way.
It was common to find a Bo-hi on the unsharpened area. This was called the Koshi Hi. Another feature would be the thin Bo-Hi that ran the blade’s length. This was the Soe Hi.
This sword had this shape for about a hundred years in the year 700 AD. The swords created in the country were almost the same as those made in China.
During that period, it was common to import steel and swords from China. And it was a sword that was an inspiration for the Moroha Zukuri. It is a kind of sword that’s just like every other ancient sword – it was straight-bladed.
Walking their Own Path
Things changed during the fall of the Tang Dynasty. It was when Japan completely disconnected itself from the Chinese. This allowed them to redefine the dimensions and geometry of their techniques. It also led them to improve their heat treating and smelting techniques.
The heat treatment method is the main factor which led to the curvature of Japanese swords.
What are the Physical Aspects of the Kogarasu Maru?
The Kogarasu Maru is styled with a curved and double-edged blade. Its length is about 62.8 centimeters long.
One of the blade’s edge is shaped like a Tachi. But the difference is that its tip is balanced, and both blade edges are sharp. An exception would be the 20-centimeter concave edge close to the hilt which is a rounded area.
One Koshi Hi type of groove extends from the Tang to its transition point. This is where the blade turns into a double-edged piece. It is also invariably followed by the Soe Hi.
The hardening method yields a straight line which is the Suguha Hamon. This is on both sides of the sword’s blade.
Another Name, The Kogarasu Zukuri
The Kissaki Moroha Zukuri swords like the Kogarasu Maru, are also called the Kogarasu Zukuri. This is because the blade is shaped distinctly, and is known for its unique Sugata.
The sword is one of a kind as a link between two swords. The classic double-edged Japanese Ken, the classic Japanese Tachi, and the soon-to-be Katana.

All about the Kogarasu Maru
So, now you know a little about this very uncommon style maybe you should give it another look. The Kogarasu Maru that exists today is forged in the style of Kissaki Moroha Zukuri. It was a favored blade shape during the Nara period. Yet swords of that time featured a shorter cutting edge at the back.
The Kogarasu Maru also had better quality than swords of that time. It was more notable than the Shousouin and is on a level with the earlier Kyushu pieces. These works include those from the Ko Naminohira School or from Bungo Yukihara.
