People often confuse the terms samurai sword and katana. But are they really the same thing?! Isn’t a katana “the” samurai sword?!
While the katana is the most well-known samurai sword, it’s just one specific type among many used throughout history. The term “samurai sword” is more general and can refer to various swords used by the samurai. So, while all katanas are samurai swords, not all samurai swords are katanas. In this article, we’ll focus on their similarities and differences, applications in combat, and how to tell if the sword you’re looking at is a katana or another type of samurai sword.

What Swords Did the Samurai Use?
Samurai used a variety of swords, including:
1. Katana
2. Wakizashi
3. Tanto
4. Nodachi
5. Tachi
These swords vary in size, shape, and usage. Let’s see their characteristics and how they change from one another.
Samurai sword vs Katana: Similarities and Differences
Since these swords evolved from one another, their crafting technique is similar. They were made from the purest materials of the time. They share the same materials including steel, fittings, sharpening process etc.. Most Japanese swords feature single-edged blades designed for cutting techniques, though there are examples of double-edged katana or tachi, which are rare. They may also feature elaborate guards (tsuba) and a natural hamon formed during the hardening process.
While katanas differ slightly from other Japanese swords, they can also vary among themselves.
The biggest difference is their length, as each sword was designed according to its purpose in usage. For example, a katana was carried by a samurai at all times, while a nodachi was only used in war due to its size, making it impractical for daily carry.
Katana
The Japanese katana features a slightly curved, single-edged blade and a handle (tsuka) designed for two-handed use. It was carried edge-up in a scabbard (saya) tucked into the belt (obi). This edge-up positioning allowed for faster and smoother draws. This is also how you can tell if it’s a katana or another type, as katanas are traditionally displayed edge-up in the same way.
Primarily used for close combat, it excelled in cutting and slicing techniques due to its curvature. The pointed tip was equally effective for thrusting, making it suitable for various combat scenarios. It stands out for its balance in length, weight, and versatility. The katana is shorter than the nodachi and tachi but longer than the wakizashi and tanto.
Wakizashi
The wakizashi is a shorter sword with a slightly curved blade. It was used by samurais as a one-handed weapon for close-quarters combat and indoor use. Its shorter length makes it highly maneuverable and easier to draw in confined spaces.
This provided an advantage in tight situations. It is longer than the tanto but shorter than other types. Samurais often carry both a wakizashi and a katana, forming the daisho, which can be used if the primary weapon is dropped or in tight spaces where a longer sword is impractical.

Samurai Tanto
The tanto is a small, straight or slightly curved-bladed dagger used by samurais. It was primarily a stabbing weapon for close-quarters combat and emergencies. Its compact size makes it highly maneuverable and easy to conceal, offering a significant advantage in surprise attacks or as a last-resort weapon. The tanto is shorter than the other blades .
Samurais often carried the tanto as a backup weapon, ensuring they were always armed, even in situations where larger swords were impractical or dropped.
Nodachi
The nodachi/odachi is a large, two-handed sword with a long, curved blade. It was used by samurais primarily on the battlefield/open-field for cutting down enemies from a distance.
The length and weight give it tremendous cutting power, making it very effective against cavalry and infantry. However, its size makes it less maneuverable and harder to draw quickly. The nodachi is the longest japanese sword.

Tachi
The tachi is a long, curved sword that predates the katana. It was primarily used by samurais on horseback, allowing them to deliver powerful slashing attacks. It’s design includes a more pronounced curve, which makes it well-suited for cutting from an elevated position.
The tachi is longer than the katana and wakizashi but shorter than the nodachi. Samurais wore the tachi edge-down, unlike the katana, which is worn edge-up. This practical design and its effectiveness in cavalry combat made the tachi a preferred weapon for mounted samurais.

Handle(Tsuka) and Guard(Tsuba)
- Guard of a katana. Elaborate and functional.
- Tachi. More ceremonial, yet elaborate and functional.
- Wakizashi. Designed more for functionality.
- Nodachi. Designed for functionality and often larger.
- Tanto. Wooden handle, no guard.
The handles of these swords have similarities but also notable differences:
Katana: The handle is wrapped in ray skin (samegawa) and then tightly bound with silk or cotton (ito) and secured with mekugi pegs. It feature a guard that can be elaborate or simple.
Wakizashi: Same fittings are used while the guard often is more simple and focus on functionality.
Tachi: Similar materials are used for the handle, but the guard (tsuba) and fittings are often more elaborate or ceremonial looking.
Nodachi: The handle is longer to provide better leverage for its size and weight, also wrapped similarly to the katana. The tsuba is usually larger due to the sword’s size.
Tanto: Traditional tantos often have wooden handles, but some feature ray skin (samegawa) and silk or cotton wrapping, similar to other types. Many tantos have no tsuba, or if they do, it is very small.
Tang (Nakago)
The tang, or nakago, is the unsharpened part of the blade that extends into the handle.
Full Tang: All traditional Japanese swords, are typically constructed with a full tang. This design provides maximum strength and balance, as the blade extends through the entire length of the handle.
Signature (Mei): The nakago often bears the maker’s mark or signature, known as the mei. This signature includes the swordsmith’s name and sometimes the date and location of manufacture. These marks not only authenticate the blade but also add historical and cultural value.
Scabbard (Saya)
All samurai swords feature saya made with similar materials, typically wood, which is often lacquered for durability and aesthetics. However, they vary in size and curvature according to the sword they house.
The level of ornamentation can also differ depending on usage. If it is for ceremonial use, it may feature more elaborate designs.
The end of the saya, called the kojiri, can be simple or highly decorated. Sageo (cord) can vary in material and style, depending on the rank and personal taste of the samurai.
Why Katana is The Best Samurai Sword?
When comparing katanas with other types of samurai swords, they stand out because of their balance. Essentially, tachi and nodachi were bigger, which made them heavier and slower. The katana combined the best features of these earlier swords, much like how the bastard swords in Western traditions combines the advantages of both one-handed and two-handed.
The katana retained the cutting power of the tachi and offered improved balance and maneuverability. This refinement resulted in a sword that was not too long or short, striking an ideal balance that made it faster, more efficient, and versatile in various combat situations.
Last Words
Though the samurai are no longer present today, these Japanese warriors are remembered as some of the most fearsome fighters in history. Among the various weapons they used, the katana is considered the ultimate weapon.
Its perfect balance, versatility, and superior craftsmanship have made it an iconic symbol of the samurai’s skill and honor.
