What Makes a Dive Knife Special?

September 25, 2022 3 min read

A dive knife is a multi-purpose tool that is used by divers to pry and dig. It is small and corrosion-resistant, and is made from a variety of metals. It also has both serrated and plain edges. These features make it a handy tool for any diver, so we'll help you choose the right knife.

Divers Carry Dive Knives to Dig or Pry

Dive knives are tools that divers carry with them during a dive. They should be long enough to easily cut through rope and have a serrated blade for cutting through rope. They should also have a full-tang blade, meaning that the metal that makes up the blade extends all the way through the handle. This means that the entire knife is a single piece, rather than two parts, which can compromise the knife's strength. A full-tang knife should also be made from high-quality steel, which can resist corrosion and provide excellent edge retention.

Diving knives are also commonly used to free entangled divers. Many divers have been tangled in fishing nets or monofilament lines, which are notorious for trapping marine animals.

They Are Made of Rust- and Corrosion-Resistant Metals

The best Dive Knifes are made from rust and corrosion-resistant metals, which means you can use them without worry about rusting. However, they still require periodic sharpening to maintain their edge. A good example of a good dive knife is the Mako diving knife.

N680 steel, for example, is a high chromium steel with a high nitrogen content. N680 steel is very corrosion-resistant and can hold an edge quite well. This type of steel is cheaper than H1 steel, but its edge retention isn't as good as 154CM steel.

A new super steel, known as M390, has been developed by Bohler-Uddeholm. This type of steel is made from third-generation powder metal technology and has excellent wear and corrosion resistance. The combination of chromium and molybdenum creates a super-sharp blade that's difficult to dull. But unlike the rust and corrosion-resistant S30V, M390 can be difficult to sharpen.

They Have Serrated and Plain Edges

Dive knives are useful tools for underwater exploration and survival. They are usually equipped with a sheath and straps that hold them securely to the user's leg or forearm. A diver can use the knife to free themselves from the water or to anchor to the sea floor. It can also be used as a tank knocker if necessary.

Depending on your needs, some dive knives have both plain and serrated edges. Others have the serrated edge separated from the plain edge to maximize cutting action. In addition, many have a line-cutting notch. This is a useful feature when snagging fish or cutting nylon line. A diver should keep the knife sharp, either plain or serrated, by sharpening it with a simple sharpening tool.

They Are Smaller

Dive knives come in different sizes, shapes, materials, and colors. There is no right answer to how big dive knife should be. Some are big and bulky while others are smaller and easily carried around. Choosing the right size for you depends on your personal preference. Smaller knives are often easier to use for beginners and are the most practical. These tools are designed to help you keep yourself safe while underwater.

A dive knife is a multi-purpose tool that features a dual-sided blade with a serrated edge on one side and a smooth edge on the other. A dive knife can be a great tool if you need to cut a net, wire, or even a fishing line. The blade measures about four inches long and is sharp enough to slice through fish or a line.

They Are Easier to Stow

Dive knives are often made of lightweight alloys that are easier to stow and clean than steel knives. However, they must be properly cleaned after each dive. Titanium is a great choice for divers because it is corrosion resistant and less likely to rust. Titanium knives also have a removable plastic handle that is comfortable to hold.

Dive knives are not necessarily the most useful tools on a dive, but they are a useful backup. They are often carried to cut through entanglement, but divers should never use knives to fight off sharks.
