1. Blade material
The blade of a dive knife is one of the most important components of the knife. It is the part of the knife that will be used to cut through materials, and it must be able to withstand the harsh conditions of the underwater environment. A high-quality stainless steel alloy is the best material for a dive knife blade because it is strong, durable, and corrosion-resistant.
Stainless steel is an alloy of iron, chromium, and other elements. The chromium content in stainless steel is what makes it resistant to corrosion. The higher the chromium content, the more corrosion-resistant the steel will be. For a dive knife, a chromium content of at least 13% is recommended.
In addition to being strong and corrosion-resistant, stainless steel is also relatively easy to sharpen. This is important for a dive knife, as it will need to be sharpened regularly to maintain its cutting edge.
When choosing a dive knife, it is important to consider the blade material. A high-quality stainless steel alloy is the best choice for a dive knife blade because it is strong, durable, and corrosion-resistant.
2. Blade shape
The blade shape of a dive knife is an important consideration, as it will affect the knife’s performance. A general-purpose dive knife will typically have a straight blade, which is suitable for a variety of tasks, such as cutting rope, kelp, and other materials. A knife designed for cutting fishing line may have a serrated blade, which is more effective at cutting through tough line.

3. Handle material
The handle of a dive knife is an important factor to consider when choosing a knife. The handle should be made from a comfortable, non-slip material to ensure that the knife is easy to grip, even when your hands are wet. This is especially important in emergency situations when you need to be able to access your knife quickly and easily.
There are a variety of materials that can be used for dive knife handles, including rubber, plastic, and metal. Rubber handles are comfortable to grip and provide a good non-slip surface. Plastic handles are also comfortable and non-slip, and they are often more durable than rubber handles. Metal handles are durable and corrosion-resistant, but they can be cold to the touch and slippery when wet.
When choosing a dive knife, it is important to consider the material of the handle. A comfortable, non-slip handle will help to ensure that you can use your knife safely and effectively.

4. Sheath
The sheath of a dive knife is an important part of the knife system. It protects the knife from damage and prevents it from falling out of its holder. A good sheath will be made from a durable material, such as Kydex or Cordura, and will have a secure closure, such as a Velcro strap or a snap button.
-
Facet 1: Protection from the elements
A good sheath will protect the knife from the elements, such as water, sand, and dirt. This is important because exposure to these elements can damage the knife and make it less effective. For example, salt water can cause the blade to rust, while sand can cause the blade to become dull. A good sheath will help to keep the knife clean and dry, which will extend its lifespan and keep it performing at its best.
-
Facet 2: Secure retention
A good sheath will also have a secure closure to prevent the knife from falling out. This is important for safety, as a loose knife could be lost or could fall out and injure someone. A secure closure will also help to keep the knife in place when you are diving, so you can be sure that it will be there when you need it.
-
Facet 3: Ease of access
A good sheath will be easy to access, even when you are wearing thick gloves. This is important because you may need to access your knife quickly in an emergency situation. A sheath that is difficult to open could delay you and put you at risk.
When choosing a dive knife, it is important to consider the sheath. A good sheath will protect the knife from damage, keep it secure, and be easy to access. These factors are all important for ensuring that you have a safe and enjoyable diving experience.
5. Size
The size of a dive knife is an important consideration, as it will affect the knife’s portability and ease of use. A knife that is too large will be difficult to carry and may be cumbersome to use, while a knife that is too small may not be able to perform the tasks that you need it to do.
-
Facet 1: Portability and ease of use
The size of a dive knife will affect its portability and ease of use. A knife that is too large will be difficult to carry on your dive belt and may be cumbersome to use, especially in tight spaces. A knife that is too small may not be able to perform the tasks that you need it to do, such as cutting through rope or kelp.
-
Facet 2: Visibility and accessibility
The size of a dive knife will also affect its visibility and accessibility. A larger knife will be more visible and easier to access in an emergency situation. However, a smaller knife may be less visible and more difficult to access, especially if it is hidden under your dive gear.
-
Facet 3: Personal preferences and comfort
Ultimately, the size of a dive knife will depend on your personal preferences and comfort. Some divers prefer a larger knife that is more visible and easier to use, while others prefer a smaller knife that is more portable and less cumbersome.
