Choosing the Perfect Scuba Dive Knife
The first thing you want to consider is what your diving knife should be made of. Titanium dive knives tend to be extremely resistant to corrosion and quite strong. They require next to no maintenance but can be difficult to sharpen. On the other hand, steel knives are easy to sharpen but need much more maintenance to keep up.
However, even if you know you want a titanium or steel knife, there are some other things you should consider.
Size of Knife
You might think that having a larger knife is always better than a smaller one, but that isn’t true in all cases. Those who plan to use a dive knife for cutting lines, kelp diving, or spearfishing will need various sizes of dive knives depending on the situation. Recreational divers often do well with a small blade as you won’t be using it on a regular basis.
Most diving knives are created with a folding blade or a fixed blade. Those with a fixed blade typically come with a sheath for safe storage. This blade has the advantage of being able to be taken out with a single hand. Foldable knives are lighter and smaller and can lock in the open position for safety. However, this can be harder to open with a single hand.
Two things should be looked at when it comes to the shape of a scuba diving knife. Both the tip and the edge shape will make a difference in how the knife works and what it does best.
The edge of the blade can be serrated or straight depending on your need. Straight blades are great at cutting nylon and plastic while serrated blades cut natural fibers and kelp better. Some knives include both which gives you the advantage of both options.
As far as the tip of the blade, it can be blunt, sharp, or something in between. Blunt knives are ideal for chiseling, prying, hacking, and digging. On the other hand, a sharp tip can puncture and cut well, which makes them a top choice as a spearfishing knife.
Choosing the Knife for Your Diving
When you take all of these things into consideration, you will find yourself close to finding the perfect knife for your adventures in underwater diving. If you know what you plan to use the knife for, that is half the battle. Many of the other choices rely directly on that as well as your own preferences. Each of the knives shown here today are high-quality options that should meet your needs after you dive into the sea.
