Zenitsu Sword

Made to replicate Zenitsu Agatsuma’s Nichirin sword from Demon Slayer, our version of this Zenitsu katana is made of hand-forged carbon steel with intricate lightning etched throughout the blade. This Zenitsu sword from Demon Slayer is a stunning weapon that has captured the attention of anime fans around the world.

The Nichirin sword is one of the most important weapons in the Demon Slayer universe, and each sword is unique and personalized to the wielder. Zenitsu's sword is no exception, and its bright yellow color and intricate design make it a standout piece.

Our replica Zenitsu sword is hand-crafted from high-quality 1060 carbon steel, which provides strength, durability, and a sharp edge. The blade is also heat-treated to ensure its functionality in combat.

To complete the Demon Slayer Zenitsu sword, we’ve recreated the circular handguard with decorative organic plant motifs. Just like the actual Demon Slayer Nichirin sword, the handle wrappings are white layered over yellow triangles. At Swords of Northshire, we offer a replica version of this Zenitsu sword that is perfect for collectors and fans of the show.

While our demon slayer sword won’t turn yellow like Zenitsu’s, we also doubt you’ll be encountering real demons during training and combat.

We pride ourselves on our top-notch customer service. We’re in direct contact with you regarding your order from start to finish. We also send pictures of the finished sword for your approval (and excitement!) before shipping. Other companies may accept orders and rush to fulfill them as soon as possible, whereas all of our swords are hand-forged and made to order by master smiths using the time-honored traditional Japanese & Chinese techniques. These swords are not fashioned on an assembly line; each is crafted with the care & respect the heritage deserves.

We refer to Japanese Quality to emphasize the difference from swords that are Made in China and of low quality & mass produced. All of our swords are fully handmade-to-order in the traditional way they have been forged for many generations. Many Longquan swordsmiths received their knowledge directly from Japanese forges; there is a rich history of information sharing between the two cultures. In these modern times, a Japanese Katana and a Longquan Katana are functionally the same.

Forever guarantee: We stand behind the quality of our swords. After your sword is created at the forge, we will send you pictures and will only ship after your approval. If at any time you have issues with the craftsmanship of your sword, please reach out to us and we will do our best to make things right.

Unless indicated otherwise, every sword is hand-forged and made-to-order for a high-quality & unique product created for you. This intricate process takes 3-4 weeks to complete. We’ll send pictures of your sword by email for confirmation (please whitelist sales@swordsofnorthshire.com to make sure you get our email). Tanto and wakizashi swords usually take around 4 weeks. Highly customized swords such as blades of a custom length or custom painted scabbards will typically take 4-5 weeks. For most orders, we estimate 4-6 weeks from the time the order is submitted to when you receive it. If you need a sword by a specific date or within a shorter time frame, contact us and we can see about prioritizing your order.

We ship to anywhere in the United States for free! For all other countries, we offer a flat shipping rate of $19.
