What is a katana, and is it the same as a samurai sword?

The katana is a traditional Japanese sword known for its curved blade, precise length, and razor-sharp edge. Often referred to as a samurai sword, it was used by samurai warriors and is admired for both its function and artistry.

What defines an authentic katana sword?

An authentic katana is hand-forged using traditional Japanese techniques. It features a curved blade, intricate steel patterns, and carefully crafted elements like the tsuba and handle. Many katanas also include a groove called bo-hi to improve handling and reduce weight.

How is a katana sword made?

A handmade katana is forged through a precise Japanese process. The steel is repeatedly heated, folded, and hammered to enhance strength. After shaping, the blade is tempered to create a sharp edge and a distinct hamon pattern, making each sword unique.

Which katana should I choose as a beginner?

For beginners, we recommend a durable and affordable katana with carbon steel, full tang construction, and a traditional design. This provides a good balance between performance, safety, and ease of use.

Can I customize my own katana?

Yes. Our custom katana builder allows you to choose every element of your sword — from the blade length and steel type to the guard, handle wrap, and engraving — to create a katana that reflects your unique style.

Anatomy of a Katana – All the Parts Explained (Plus Blade Steel Types)

June 17, 2025

Introduction

Whether you're buying your first katana or customizing your own, understanding the anatomy of a katana is essential. From the razor-sharp blade to the hand-wrapped handle, each component plays a crucial role in the sword's performance, balance, and beauty.

This comprehensive guide breaks down every component of a katana — and at the end, we'll explain the most common types of steel (1060, T10, Damascus, and more) to help you make the right choice for 2025.

Main Parts of a Katana

1. Blade (Ha)

The heart of the katana. It's a curved, single-edged steel blade designed for both cutting and slicing. A well-forged blade displays a visible hamon — a wavy line that reflects the differential tempering process and indicates quality craftsmanship.

2. Spine (Mune)

The back of the blade, opposite the cutting edge. This unsharpened section helps balance the blade's flexibility and strength, contributing to the katana's overall structural integrity.

3. Tip (Kissaki)

The pointed end of the blade, primarily used for thrusting attacks. A properly shaped kissaki is a hallmark of a high-quality katana and requires skilled craftsmanship to achieve.

4. Guard (Tsuba)

Located between the blade and the handle, the tsuba protects your hand from sliding onto the blade and helps balance the sword. Some tsubas feature minimalist designs, while others are ornate works of art that reflect traditional Japanese aesthetics.

5. Habaki (Blade Collar)

A small metal wedge that securely locks the blade inside the saya (scabbard) and ensures a tight, rattle-free fit. It also helps transfer force efficiently between the blade and handle during use.

6. Handle (Tsuka)

The grip section, traditionally wrapped in cotton or silk cord over rayskin (samegawa) for enhanced grip. It's built around a full tang construction and secured with bamboo pegs (mekugi) for maximum stability and safety.

7. Mekugi (Bamboo Pegs)

These essential components hold the handle firmly to the blade tang. Most quality katanas use one or two mekugi for optimal safety and structural integrity.

8. Pommel (Kashira)

The end cap of the tsuka, often matched in style and material with the tsuba. It provides essential counterweight to balance the blade and serves as an aesthetic finishing touch.

9. Saya (Scabbard)

The protective wooden sheath that houses the blade when not in use. Traditionally lacquered and fitted with cord wrapping (sageo) for secure display or wearing at the side.

⚔️ 1060 Carbon Steel

This remains one of the most popular and reliable steels for functional katanas in 2025. It offers an excellent balance between flexibility and cutting power — perfect for beginners or regular practice. The steel is easy to maintain and provides consistent performance.

⚔️ 9260 Spring Steel

Renowned for exceptional elasticity and resistance to bending, 9260 katanas are ideal for intensive use or tameshigiri (cutting practice). While less traditional than carbon steel, it offers superior durability for modern practitioners in 2025.

⚔️ T10 Tool Steel

A premium steel choice known for outstanding edge retention and hardness. T10 katanas are truly battle-ready and often display dramatic, pronounced hamon lines. This steel type has gained significant popularity among serious collectors throughout 2025. See a T10 steel katana

⚔️ Damascus Steel

Not a specific steel type, but rather a sophisticated forging technique. Damascus blades are layered and folded multiple times to create distinctive wavy patterns. These blades perfectly combine performance with stunning visual appeal, making them highly sought after by collectors who appreciate both function and artistry. See a Damascus katana
