Dive Knives 101: Features and Maintenance
Diving is an exciting and adventurous activity. While it offers incredible experiences, it can also present unexpected challenges. One of the most essential tools that a diver must possess is a scuba diving knife. A scuba diving knife is a specialised tool designed for underwater use. It is crucial for divers to have a good understanding of the different features and maintenance required for dive knives so that your dive can be as safe as possible.
Features of Dive Knives
Blade Material
There are different types of blade materials available, including stainless steel, titanium, and ceramic. Stainless steel is the most common blade material because it is durable and can resist corrosion. Titanium is stronger than stainless steel and is more resistant to corrosion, making it an excellent option for divers who dive in saltwater. Ceramic blades are incredibly sharp and can retain their edge for longer, but they are more brittle and require more care.
Blade Edge
The blade edge is another essential factor to consider. Dive knives can have a serrated edge, straight edge, or a combination of both. Serrated edges are ideal for cutting through thick materials, such as ropes and fishing lines. Straight edges are better for clean cuts on softer materials like kelp or fish. A combination of both edges can provide a versatile cutting option.
Blade Length
Dive knives come in different blade lengths, ranging from short to medium and long. Short blades (less than 3 inches) are ideal for divers who want a compact and lightweight knife that is easy to carry and manoeuvre. They are typically used for general cutting tasks, such as cutting through fishing lines, ropes, or seaweed. Meanwhile, medium blades (between 3 and 5 inches) are a versatile option that can be used for a wide range of cutting tasks. They are ideal for divers who want a knife that is slightly larger than a short blade but not as bulky as a longer blade. Medium blades are also useful for spearfishing, as they can easily cut through the skin and bones of small to medium-sized fish. Long blades (more than 5 inches) are typically used for heavy-duty cutting tasks, such as cutting through thick ropes, cables, or even metal. They are an excellent option for divers who need a knife for industrial or commercial diving activities. However, long blades can be bulky and cumbersome, and thus, they are not the best option for recreational divers who only need a knife for general cutting tasks.
Handle Material
The handle material is also essential to consider. Common materials used for dive knife handles include rubber, plastic, and metal. Rubber handles offer better grip and are more comfortable to hold. Plastic handles are lightweight and easy to clean, while metal handles are the most durable but can be slippery when wet.
Types of Dive Knives
BCD Mounted – A BCD-mounted knife is ideal for divers who want a knife that is always within reach. It can be useful in emergency situations when a diver needs to cut themselves free from an entanglement quickly.
Leg Mounted – Leg-mounted knives are a popular choice among divers who prefer a low profile and comfortable option. They are useful for general cutting tasks, such as removing fishing lines or cutting through seaweed.
Wrist Mounted – A wrist-mounted knife is an excellent choice for divers who want a knife that is easy to access but not bulky. It can be used for general cutting tasks or in emergency situations when a diver needs to cut themselves free quickly.
Line Cutter – A line cutter is a specialised type of dive knife used to cut through fishing lines, nets, and other entanglements. It is typically a small, compact knife that can fit easily in a pocket. Line cutters are useful for divers who do a lot of spearfishing or encounter fishing nets frequently.
Maintenance of Dive Knives
After each dive, it is essential to clean the scuba diving knife thoroughly. Rinsing the knife in freshwater or saltwater can help remove any dirt or debris that may have accumulated on the blade. After cleaning, it is crucial to dry the knife properly. A damp blade can lead to rust, which can affect the knife’s effectiveness. Once it has dried, you should apply lubrication to the blade and store it in a sheath so as to prevent rust and corrosion. Regular sharpening can also help to maintain the knife’s edge. This way, you can ensure that it is always ready for use.
