It goes without saying, if you have your own set of scuba gear then it is much easier to dive more often. When you have your own regulator, BCD, mask, fins, etc. it is much simpler getting into specialized types of diving.
Beyond the basics, it is certainly a good idea to have some dive accessories on hand. If you plan on doing some spear fishing or just want to be covered in case of emergencies, it is very useful to have a diving knife. But how can one know what is the best dive knife for their specific needs?
There are several things to consider when choosing a diving knife to suit your needs. Think about what type of diving you plan on doing, how much you would like to spend, and what various features you want the knife to have. After doing so, check out the models listed that fit that criteria.
Steel or Titanium?
There are two different materials that are generally used to make diving knives. Steel and titanium. For the purpose of this article, we will only be listing titanium diving knives, but it is important to know the difference between the two.
Steel dive knives are very easy to sharpen, but require a lot of maintenance to prevent rusting. Steel diving knives generally come in two different allows – 300 and 400. The 300 steel alloy, which is close to that of a titanium knife, requires less maintenance but is much harder to sharpen. The 400 steel alloy on the other hand, is more likely to rust, but at the same time it keeps sharp edges a lot better than the 300 alloy.
Titanium knives are what most divers use. Titanium dive knives are incredibly durable and strong, and breaking one is a very difficult thing to do. Additionally, titanium knives are very resistant to corrosion, so there is not much risk of rusting. Titanium knives are also maintenance free, which is very convenient. The only downside however, is that they are quite difficult to sharpen.
Size is important
Size is a very important thing to keep in mind when choosing a titanium dive knife. For recreational divers, a small knife with a four-inch blade is generally the way to go. With this sort of knife, you’ll only be using it in case you get tangled, otherwise it will most likely spend most of its time in its case. If you plan on using the knife for kelp diving, spearfishing or cutting fouled lines, then you’ll need a bigger blade depending on the situation.
What kind of blade do you need?
Dive knives generally come with either one of two types of blades – fixed or folding. Knives with fixed blades are stored in a sheath for safety. One of the main advantages of this kind of knife is that it can be removed with one hand. Knives with folded blades are smaller and lighter, and they lock in the open position for safety reasons. While more convenient, they are more difficult to open with one hand.
Blade shape is important
It’s important to consider the shape of a dive knife blade. There are two parts of the blade to look at – the edge and the tip. The edge of the blade can be either straight or serrated. A straight edge is better for cutting plastics or nylon rope, while a serrated edge is better at cutting kelp and natural fibers. The best course of action is to get a knife that has both straight and serrated sections of the edge.
The tip of a blade can be either blunt or sharp. A blunt tip is great for digging, chiseling, and prying. A sharp tip is great for cutting and puncturing, making them ideal for spearfishing. Sharp tips can be quite dangerous though and should be used with caution.
