Things to Consider in Diving Knife Maintenance
A dive knife can be an invaluable tool for recreational divers and spear fishermen. If you get caught in a fishing line, net or seaweed, this small accessory can make all the difference. A good scuba diving accessories does not need to cost a fortune. Its main purpose is to be easy to carry around. Every diver knows that a dive knife can serve as an anchor to the sea bed in heavy currents, or act as a tank knocker to get your buddy’s attention. But if you are looking to buy one, it's important to think about what you intend to use it for and choose the right tool for the job. Before you buy a diving knife, make sure it is suited for what you want to use it for so that it does not hinder your diving adventures. There are a few factors you need to consider when looking for the best knife for your needs.
1.The Material of the Dive Knife
The material of which the dive knife’s blade is made decides the performance as well as the longevity of the dive knife. Titanium and steel are two common materials used to forge diving knife blades.
Titanium is a light, corrosion-resistant metal that easily resharpens and holds its edge. Stainless steel is also a great choice for a diving knife because it is strong and durable. With proper care, this material can last many years. A special feature of titanium diving knives is that they are strong but lightweight. They weigh almost twice as little as similar size steel dive knives. It can also be hard to sharpen. Titanium knives are generally expensive. Titanium knives are easy to care for and durable.
If you go for the steel material diving knives, they are easy to sharpen. But you need to stick to regular maintenance to keep them away from rusting. If you want a knife that you can rely on for many years of diving, then this is the one for you.
Steel knives consist of two alloys: 300 and 400. The primary characteristic of 300 alloy is that it is resistant to high corrosion. But it needs sharpening more than alloy 400 which can hold its edge much better. The problem with the 400 alloy is that it is vulnerable to more rusting.
2.Type of Blade
A diver's knife can be either a fixed blade or a folding blade. Fixed blades offer the best performance, but they are not as easy to carry as folding knives. Regardless of the blade's style, it should be strong and sharp enough to cut through lines that may get tangled around your body during a dive.
Dive knives with fixed blades are generally considered to be more reliable. You can easily take this type of knife out and use it with one hand, making it a great option for divers who are looking for an essential tool that is easy to access and use. Divers who plan on going beyond shore diving will also appreciate knowing that most dive knives with a fixed blade also come with a sheath for safe storage.
Foldable knives have the added convenience of taking up less space and being safer to carry. However, these models can be hard to open with one hand, so they are not recommended for experienced users.
3.Edge of the Blade
The blade of your knife can be either straight or serrated. A straight blade is best for slicing things and cutting plastics and nylon rope. A serrated blade, on the other hand, will saw through natural fibres and kelp. A knife with a straight and serrated edge, as well as a notch in the blade for cutting the fishing line, is the best option.
4.Tip of the Blade
The tip of the blade can be blunt or sharp. If you don’t plan to use your knife for stabbing and piercing, a blunt tip makes the knife safer by preventing you from accidentally puncturing hoses, exposure suits or BCDs. The point allows divers to easily spike their prey, but also makes it more prone to accidents so we always recommend sheathing your spearfishing knife when diving.
Dive Knife Maintenance Tips
1. Inspect the knife for corrosion
Before you start diving, we advise you to inspect your knife for corrosion. If you discover that rust spots appear on your knife, use a cleaning solution and wipe the blade with a clean cloth, a towel or some soft steel wool
2. Check the locking mechanism
We recommend that you disassemble parts of your knife from time to time. Remove the handles and give them a thorough clean, making sure no salt or sand has found its way into the inner parts of your knife.
3. Disassemble the knife
We recommend that you disassemble parts of your knife from time to time. Remove the handles and give them a really thorough clean, making sure no salt or sand has found its way into the inner parts of your knife.
4 Sharpen if necessary
To keep your knife in good condition, make sure to sharpen it when necessary. If you have a dull edge, note that a fine metal file is the best way to sharpen it. This will create a rough, but sharp edge.
The most common way to sharpen serrated blade knives is with a sharpening rod. Run the rod along each serrated scallop at an angle of the bevels.
5. Rinse with fresh water
Dive knife care is simple. After each dive, rinse your knife with fresh water and scrub it to remove any leftover salt or debris. Dry the knife thoroughly before storing it to prevent rust. Do not use soap on the blade, since this will slow down the corrosion resistance of your blade.
