Overview
Bugei - Armorer's Katana - 28" Blade
Some katana are crafted to honor the memory of great leaders, warriors, and legendary battles from Japan’s storied past. This katana is dedicated to the legendary swordsmith Nagasone Kotetsu of the Edo period. Born into a family of armorers, Kotetsu transitioned into blade forging, and his swords quickly gained fame for their unmatched strength and sharpness. It was said that his blades could slice through a kabuto (helmet)—a feat that should remain in the realm of myth. His work was defined by an exceptional combination of durability and cutting power. While there is some debate over how many swords he actually produced, numerous counterfeit pieces have been found bearing his signature. Regardless, the enduring legacy of his craftsmanship continues to inspire to this day. While it’s beyond the scope of this tribute to recount every detail of Kotetsu’s life, collectors, aficionados, and practitioners alike should make it a point to study his contributions to the sword-making world.
This katana, the Armourer's Katana, honors the memory of this great swordsmith. Its uniquely shaped tsuba features an intricate pierced yanone (arrowhead) motif, echoed in the menuki, creating a powerful visual connection to Kotetsu’s enduring influence. Simple, elegant, and strong—just like the blades that earned him his legendary reputation.
Two words best describe this katana: hidden strength. The katana’s power is hidden beneath the quiet elegance of its design—its blackened, textured handle furniture, and the refined silver menuki. The premium dark brown Japanese cotton ito wraps around authentic samegawa (ray skin) in a traditional diamond pattern, offering both aesthetic beauty and functional grip. The dark chocolate brown saya, paired with a contrasting light brown sageo, buffalo horn kurikata, and kojiri, completes the visual theme of strength and simplicity.
The blade itself is forged and folded from a blend of T10 and 1055 steels, creating a distinctive hada (grain) pattern that enhances both the visual beauty and strength of the blade. The hamon (tempering line) takes the form of a flowing o-choji pattern along its entire length. More detailed specifications can be found below.
We believe Nagasone Kotetsu would be proud to see this katana, a tribute to his legacy. It embodies the principles of strength, resilience, and simplicity, wrapped in the form of a lethal weapon. It is our hope that this katana will one day stand as legendary as the man who inspired it.

The Maker
Bugei
At Bugei, our interest is in the swords of the ancient Samurai. The shapes, lengths, nakago, tsuka, etc. reflect an era when swords were still used for combat. Our swords are used by more modern sword styles and our Wave koshirae blades can be custom designed to fit more modern styles that are currently practiced in Japan, however this is not our prime directive. Most of the modern swords produced in Japan would not be practical for the uses that the Samurai required of their blades. The majority of currently produced blades are too thin and flat ground to stand up to the rigors of actual battle use. In real world terms a broken sword often meant death. In the 1850’s in Japan two samurai were killed in different incidents because their swords broke during fights. One of these samurai was Nakai Shogoro killed at the Teradaya Inn and the other, named Arima, was killed at the Tenmanya Inn. All cultures tend to rewrite history and the Japanese are no exception. Some modern styles for instance do not want to see things like tameshigiri become a more practical training for combative type of cutting and a more realistic test of blade performance. Modern Japan and the vast majority of modern Japanese martial arts, with some exceptions, do not reflect combat intent or function and only partially reflect the military arts of the Samurai. With this in mind we are drawn to the styles of blade and the military arts that reflect the Samurai when they were masters of their own fate.
The Edo period was the beginning of the end for Samurai martial culture, the Meiji restoration put nails in the coffin, and World War Two with a few notable exceptions put the coffin in the ground. In ancient Japan the size, shape, and styles of blades had a wonderful diversity that is missing in the present. We are interested in reproducing some of this swords for both the collector and the practitioner. Our desire is to produce, at the best possible prices, swords that reflect those ancient traditions that fire our imagination with the skill and courage of the Samurai in battle. Our most recent introduction is a shobu-zukuri sword of the type that was used to great effect by the Samurai when battling the Mongol invasions during the 14th century. Modern Japan may value form more than function however for their distant ancestors form had to follow function, it was a question of survival and warriors are nothing if not pragmatic. Our long nakago and two mekugi provide both strength and safety. Our choice of tsuka lengths from 9″ to 16″ provide for styles both ancient and modern. Our exclusive use of the superior and difficult to come by Swedish Powdered Steel assures you our customer that your sword is made from the very best material available.
