Diving Knife: Why Is It So Important?

Diving knives are essential tools for any scuba diver. They can be used for a variety of purposes, from cutting through fishing line to freeing yourself from entanglement. However, many divers tend to underestimate the importance of a diving knife and fail to carry one on their dives. In this article, you are going to learn why a diving knife is so important and the different types of knives available.

Why Do You Need a Scuba Diving Knife?

Diving knives serve many purposes. Here are some reasons why carrying a dive knife is essential for divers, 

1. Safety First

Diving is an activity that comes with inherent risks, and divers need to be prepared for any situation that may arise. One of the most common risks for divers is entanglement. When diving, you may come across fishing lines, nets, or even kelp forests that can entangle you, making it difficult to move. A diving knife can be used to cut yourself free from these entanglements quickly.

Similarly, if you are diving in an area with strong currents, you may get caught on a reef or rock, and a diving knife can be used to free yourself. The knife can also be used to cut through ropes or lines that are tied to a boat or anchor, allowing you to surface safely.

2. Self Defense

While rare, underwater encounters with dangerous marine creatures such as sharks or barracudas can occur. A diving knife can be used as a last resort for self-defense in such situations. While it is important to note that the best course of action is to avoid contact with these creatures, having a diving knife on hand can provide a sense of security and comfort to divers who may encounter them.

3. Emergency Tool

In addition to its use for self-defense and freeing yourself from entanglements, a diving knife can also be used as an emergency tool. If your equipment happens to malfunction, a diving knife can come to your rescue. It can be used to fix a broken piece of gear, such as a fin strap. In the unlikely event that you need to perform an emergency tracheotomy, a diving knife can be used for that purpose as well.

What to Consider When Buying a Scuba Diving Knife?

When choosing a diving knife, there are several factors to consider, including the type of diving you will be doing, the conditions you will be diving in, and your personal preferences.

First and foremost, you should consider the size of the knife and the type of blade, whether it’s serrated or straight-edged. You should also consider the material of the blade and handle, as well as the overall weight and balance of the knife. Other factors to consider include the ease of use and accessibility, such as the design of the sheath and whether it can be mounted to your diving gear. Most importantly, you should inquire into any legal requirements or restrictions for carrying a dive knife in the area where you plan to use it.

Different Types of Dive Knives

There are several types of diving knives available, each with their own unique features and benefits.

  • Blunt Tip Knives: These knives have a rounded tip, making them safer to use in close quarters. They are ideal for divers who want to use their knife for cutting and prying but do not want to risk accidentally puncturing their equipment or cutting themselves.
  • Pointed Tip Knives: Pointed tip knives are ideal for divers who need to puncture or pierce materials, such as cutting through thicker fishing lines or puncturing a metal surface. However, they are not recommended for divers who are new to diving or inexperienced with the use of diving knives.
  • Folding Knives: Folding knives are compact and easy to carry, making them a popular choice for many divers. They can be folded away when not in use, reducing the risk of accidental injury or damage to other equipment.
  • Sheath Knives: Sheath knives are typically larger and more robust than other types of diving knives. They are designed to be worn on the diver’s leg, allowing for quick and easy access in case of an emergency.
  • Line Cutter: Line cutters are small, compact knives designed specifically for cutting through fishing lines or nets. They can be attached to your BCD or worn on your wrist for quick access.

How to Maintain Your Dive Knife?

To maintain your dive knife, it’s important to rinse it thoroughly with fresh water after each use and dry it off completely before storing it in a dry and ventilated area. You should also check the blade periodically for any signs of rust or corrosion and use a rust remover if necessary. Additionally, you can apply a light coat of oil to the blade to help protect it from rust. Also make sure to inspect the handle and sheath for any signs of wear or damage, and replace them if necessary to ensure the safety and effectiveness of your dive knife.

How to Carry a Dive Knife Safely?

Carrying a dive knife safely involves securing it in a sheath that is designed specifically for diving. The sheath should be attached securely to your diving gear in a position where it is easily accessible but won’t interfere with your movement or cause any entanglement. It’s also important to avoid carrying the knife loosely or in a way that could cause it to become dislodged during the dive. Always handle the knife with care and respect, and never use it recklessly or in a manner that could endanger yourself or others.
