Samurai Blades: The Ancestors of Japanese Survival Knives

Samurai Blades: The Ancestors of Japanese Survival Knives


The samurai, renowned warriors of feudal Japan, were known for their skill in the art of sword fighting. The most iconic weapon associated with the samurai is the katana, a curved sword with a single-edged blade renowned for its sharpness and cutting power. However, the samurai arsenal was not limited to the katana alone.

In addition to their primary weapon, samurai also carried a variety of secondary tools and blades that served different purposes on and off the battlefield. These auxiliary blades were essential for daily tasks, survival in the wilderness, and for backup in combat situations. In this article, we will explore the different types of blades used by the samurai, their purposes, and their influence on modern Japanese survival knives.

1. Tanto:

The tanto is a short knife with a blade length ranging from 6 to 12 inches. It was primarily used as a stabbing weapon and was carried by samurai as a backup in close quarters combat. The tanto was also used for tasks such as cutting ropes, cooking, and everyday utility. Its sharp point and compact size made it a versatile tool for multiple functions.

2. Wakizashi:

The wakizashi is a medium-sized sword with a blade length between 12 and 24 inches. It was often worn together with the katana by samurai as a backup weapon. The wakizashi could be used for slashing attacks in confined spaces where the longer katana would be impractical. It was also carried by samurai as a symbol of status and as a tool for ceremonial purposes.

3. Tanto-Wakizashi Set:

The combination of a tanto and wakizashi in a matching set, known as a daisho, was a common sight among samurai. The daisho represented the social status of its owner, with the longer katana symbolizing the primary weapon, and the shorter wakizashi serving as a backup. These sets were not only used in battle but were also worn as a mark of honor and prestige.

4. Tanto-Wakizashi-Katana Set:

In some cases, samurai carried a complete set of three blades: the tanto, wakizashi, and katana. This set, known as the “sando” or “sandai kitae,” was reserved for high-ranking samurai and served as a symbol of their authority. The katana was the primary weapon, while the wakizashi and tanto provided backup options. This set was both practical and ceremonial, emphasizing the samurai’s role as a warrior and a leader.

5. Naginata:

The naginata is a polearm weapon with a curved blade on a long staff. It was primarily used by samurai women, known as “onna-bugeisha,” who were trained in the art of warfare. The naginata allowed the onna-bugeisha to keep enemies at a distance while providing the versatility of both slashing and thrusting attacks. The naginata was also used for ceremonial purposes and as a symbol of the samurai spirit.

6. Kama:

The kama is a sickle-shaped blade that was originally a farming tool used for harvesting crops. However, it was also adapted for combat by some samurai. The curved blade of the kama allowed for effective hooking and disarming techniques. It was considered a versatile weapon, suitable for both close-quarters combat and agricultural tasks.

7. Yari:

The yari is a spear with a straight, double-edged blade on a long shaft. It was a popular weapon among the samurai, known for its versatility and reach. The yari allowed samurai to engage enemies at a distance, making it effective both in open-field battles and for castle sieges. The yari was a common weapon on the battlefield and was also used for hunting and survival in the wilderness.

Influence on Modern Japanese Survival Knives:

The legacy of samurai blades can be seen in the design and craftsmanship of modern Japanese survival knives. These knives often draw inspiration from the traditional aesthetics and functionality of the samurai blades. They incorporate the characteristics that made the samurai blades effective for both combat and survival situations.

One notable feature is the use of high-quality steel in the construction of Japanese survival knives. The samurai blades were renowned for their sharpness and cutting ability, achieved through the use of superior steel and meticulous forging techniques. Similarly, modern Japanese survival knives prioritize the use of high-carbon steel, which offers durability, edge retention, and ease of sharpening.

Another aspect that has been carried over is the emphasis on ergonomic and balanced designs. Samurai blades were crafted to fit comfortably in the hands of the warriors, reducing fatigue and ensuring precise control during combat. This focus on ergonomic design is echoed in modern Japanese survival knives, which are carefully shaped and balanced to provide optimal handling and control in outdoor and survival scenarios.

Furthermore, the traditional forging techniques, such as the folding method, have been preserved in the production of modern Japanese knives. The folding method involves repeatedly layering and folding the steel to create a blade with a fine-grained structure, enhancing its strength and resilience. This technique, passed down from the samurai era, is still practiced by skilled craftsmen who produce high-quality Japanese knives today.


The samurai blades of feudal Japan were not limited to the iconic katana alone. Samurai carried a variety of secondary blades, such as the tanto, wakizashi, and naginata, which served different purposes in combat and everyday life. These blades were not only practical tools but also symbols of social status and honor.

The influence of these samurai blades is still evident today in the design and craftsmanship of modern Japanese survival knives. The use of high-quality steel, ergonomic designs, and traditional forging techniques has been carried over from the samurai era to create knives that excel in both outdoor and survival scenarios.

Understanding the history and significance of these ancestral blades provides a deeper appreciation for the art and craftsmanship behind Japanese survival knives. It also serves as a reminder of the enduring legacy of the samurai and their contribution to the world of blades and weaponry.
