Factors to Consider before Selecting a Dive Knife

Selecting the right dive knife is essential for any spearfisher. The perfect knife will help you stay safe, cut through obstacles and make quick work of caught fish. With so many designs, sizes, and materials available, however, choosing the right one is easier said than done.

In this section, we will discuss the factors that you should consider before selecting a dive knife. We will delve into the sub-sections of:

  1. Size
  2. Material
  3. Blade type

Exploring what to look for in each category. By the end of this section, you will have a better understanding of what features to seek in a dive knife.


When selecting a dive knife, size is key. Think about:

  • diving activity
  • knife design
  • personal preference

Folding knives are more compact. Fixed blade knives are more durable and strong. Black blades limit light, so they won’t startle marine life. Titanium and stainless steel resist corrosion. Tip profile matters too – it affects knife functionality in emergencies or hunting. A corrosion-proof knife is essential for safety. Iconic dive knife designs have lasted decades. Eg. Aqualung US Divers Knife (fixed blade), Promate Barracuda (folding, sharp edge, serrated edge), AKONA Talon (serrated edges, free and scuba diving). Size isn’t the only factor. Consider corrosion-resistance, tip profile and iconic designs.


When selecting a dive knife, several factors should be taken into account. These include corrosion resistance, safety equipment and intended use. Plus, the type of diving, material, size and design of the knife are all important. Let’s look at commonly used materials for dive knives and how they compare.

  • Stainless steel is affordable and tough. It’s also resistant to corrosion and easy to sharpen. But, it tends to be bulky and heavy, which might not be ideal for activities requiring agility like free diving.
  • Titanium dive knives are lightweight and corrosion-resistant, making them great for regular diving or saltwater.
  • Folding or foldable knives are handy for storage and transport, yet may not be as strong as fixed blade knives.

Investing in a good dive knife is vital for underwater safety. Examples of iconic spearfishing knives include:

  1. The Aqualung Squeeze Lock with a lock mechanism, stainless steel blade and ergonomic handle.
  2. The Spyderco Atlantic Salt is corrosion-resistant with a yellow handle, serrated edges and plain edge.
  3. The Cressi Skorpion is made from durable German stainless steel, with a straight and serrated edge, blunt tip for prying and line cutter.

Choosing the correct dive knife and investing in quality are key for underwater safety. With proper maintenance, a well-kept dive knife can last a lifetime.

Blade Type

Choosing a dive knife for spearfishing? Blade type is essential. It dictates how safe and efficient it is underwater.

Stainless steel dive knives have been a classic pick for years. Rust-resistant and low-maintenance.

Titanium dive knives are pricey, but offer unbeatable strength and anti-corrosion properties. A great choice for experienced divers who seek quality.

Foldable dive knives provide portability and fit easily in pockets or holsters. They are still sharp and sturdy despite their miniature size.

To maintain its condition, make sure to rinse and dry your dive knife after use. This prevents rust and increases its longevity.

Maintenance of a Dive Knife

Maintaining your dive knife is crucial to ensure its longevity and performance when you need it the most. In this section, we’ll explore the various aspects of dive knife maintenance to keep it in top-notch condition. We’ll cover the basics of:

  • Cleaning and drying the blade
  • Sharpening the edge for optimal use
  • Proper storage and preservation techniques

By the end of this section, you’ll be equipped with the knowledge to ensure your dive knife remains the most reliable tool in your spearfishing gear collection.

Cleaning and Drying

Maintaining a dive knife is a must. Cleaning and drying it is key. Here are some steps to follow:

  1. Rinse your knife in fresh water after each dive. Salt, sand, or debris can cause corrosion.
  2. Use a soft-bristled brush or sponge to clean the blades and handles. Use a cleaning agent safe for the material.
  3. Rinse again and dry it with a clean towel. Pay attention to crevices and hard-to-reach areas.
  4. If storing for a long period, make sure it’s dry. Apply a light coat of oil to prevent rust.
  5. Store in a dry, secure location out of reach of children. Away from sharp objects.

It’s essential to maintain your dive knife. Preparing for hazards while diving is important.

Sharpening the Blade

Sharpening your dive knife is a must for optimal performance and longevity. Here’s how to do it!

There are 3 types of dive knives – folding, titanium, and stainless steel. Each needs its own specific method.

For a folding knife, use a sharpening tool in a curved motion, following the blade’s edge angle.

Titanium dive knives should be sharpened with a stone and either oil or water, in one direction.

For stainless steel, angle the blade’s edge at 20-degrees on a stone and move it back and forth.

Always follow the manufacturer’s instructions. Wear gloves to avoid cuts.

Regular and proper sharpening of your dive knife will give you peace of mind while diving.

Storage and Preservation

Keeping dive knives in good condition is essential for their longevity. Whether you own a foldable or stainless steel one, following these tips will help:

  • Clean it with fresh water after each use. This removes salt, debris, and other contaminants that may cause corrosion.
  • Wipe it with a clean towel after cleaning to make sure it’s fully dry before you store it.
  • Store it in a cool, dry place to stop rust and corrosion from dampness.
  • Put a thin layer of oil or wax on it to protect it from moisture and the environment.

Choosing the right dive knife is also important for safety and function while diving. Classic dive knife designs in spearfishing history include:

  • Dagger-shaped with a long, pointed blade for piercing and cutting.
  • Blunt-tip with a flat, round tip which is safer and less likely to puncture anything.
  • Foldable knives which are compact and can be easily stored and transported.

Spearfishing is an exciting hobby, but you must be safe and carry a quality dive knife. Following the tips above will help you maintain your dive knife for successful spearfishing trips.
