What Is the Difference Between a Sword and a Knife?


For civilizations, humans have used swords and knives for protection, battles, and self-defense. These weapons may look the same and yet, they are not, owing to their material, usage, sharpness, and many other factors. 

So, in the short, and quick answer we can say that the major differences lie in components like Blade sharpness, Material Use, Weapon Usage, Weapon Length, Gripping, and Handling.

Knives blades are sharper than the swords. However, sword blades are meant to be stronger than sharper. Secondly, knives are mostly made out of stainless steel for more sharpness but swords are made up of copper or bronze for more strength. Knives are usually used for household-related purposes whereas swords are mostly used as a combat weapon. 

In this article, we will talk about what exactly they are, their major differences, and uses. So, if you are curious about the major differences between a sword and a knife, keep reading to get all the questions answered. 

Introduction to Knives and Swords

Before we talk about the differences, it is important to know the exact definition of both knives and swords.

Talking about a knife, it is a sharp blade that is attached to a proper handle for gripping. There are different types of knives available like hunting knives, pocket knives, and combat knives used as weapons and defense. 

On the other hand, a sword consists of a much longer blade attached to a thin hilt. Depending on the edge, we can differentiate it into thrusting swords, slashing swords, etc. 

Now, an obvious difference lies in the blade size of the knife and swords. However, there are many other differences that we are going to cover below. 

What Is the Difference Between a Sword and a Knife?

Some of the major differences lie in components like: 

  • Blade sharpness
  • Material Used
  • Weapon Usage
  • WeaponLength
  • Gripping and Handling 

So, let’s take a look at each one of them in detail. 

Blade Sharpness

One of the major differences between knives and swords lies in the blade sharpness. 

The sharpness of the knife’s blade is razor-sharp. By razor-sharp, it means that it is extremely pointed. 

However, when it comes to swords, it is not the sharpness that matters. Swords are meant to be used with a heavy swing force. So, the blade and edge need to be more durable to withstand the force. 

If the sword’s blade is too sharp and pointed, it may break against hard surfaces rather than cutting through. 

Also, the sword’s edge is more convex rather than concave, to give more sharpness, as seen in knives.  

Materials Used

The next difference lies in the materials used for more weapon strength. 

If I’m talking about knives, steel, or stainless steel is a great material to give the knife its sharpness and corrosion-resistant property. 

However, if we use the same materials for a sword, it may not be ideal. This is because materials like stainless steel can get brittle if the blade length exceeds. 

Additionally, stainless steel cannot help in holding the edge properly and thus, can break off. This can bring about a huge danger for both the attacker and the defender. 

Weapon Usage

When we talk about the uses of both knives and swords, we can clearly see a difference because of the versatile nature of knives. 

Due to the sharp edges, knives are mainly used for carving and cutting purposes. They are usually used more as tools rather than actual weapons. Although, certain knives like combat knives and hunter knives are essentially made for combat.

On the other hand, swords are used mostly as a weapon only and not as a tool. They function more through force rather than sharpness and hence, are not suitable for carving and cutting purposes. 

So, knives are versatile and multi-purpose in nature whereas swords are mostly for combat-based purposes. 

Weapon Length

As mentioned earlier, one of the most noticeable differences between a knife and a sword is the length difference. 

Usually, knives measure up to ten inches. We can easily carry around a knife for defense purposes due to its short length. In fact, this length is also ideal for cutting and carving purposes. 

Swords measure more than a foot and can range around two to three feet. The increased length comes as an advantage during a battle as it can have a greater reach. 

Additionally, a sword can be used as a self-defense weapon due to its shielding length. 

So, the choice is dependent on the requirements. 

Weapon Grip and Handle

Another difference we can find in both swords and knives is the handle construction. 

If we talk about a knife, near the handle’s edges, we can notice the blade’s tang. However, in the case of a sword, the tang is usually covered by the handle. 

There also lies differences in gripping both of them. While knives do not have a proper procedure for handling them, it is necessary to learn how to grip and handle a sword properly. 

For example, we do not need to have a specific position for holding a simple knife. Yet, we need to ensure that the sword’s pommel is above the belly button and at a little distance. 

So, there is proper training needed for handling a sword. 

Final Thoughts

Swords and knives both are important weapons used for various purposes. However, these differences make them ideal for mostly one type of purpose. 

So, you can consider a knife more as a tool rather than a weapon. Whereas, a sword has a proper combat use.
