1. Best blade materials for dive knife
Titanium diving knife
Titanium is by far the most popular blade material. It seems to prove best for cutting, durability and longevity. In essence, these are the most critical factors that every material should provide to the user. However, titanium is not without reason the best material for diving knives. It has proven to be good for underwater use because unlike other materials; it is itself resistant to corrosion and does not require constant maintenance. The customers said the same thing as we, which is that titanium is the best material for scuba diving knives.
After titanium, steel is the best material. It’s not quite like it, but it’s pretty good. Its disadvantages regarding titanium blade are as follows: less corrosion resistance, less sharp underwater, faster blunting but much easier to maintain than the previous one. But don’t worry, our knives are mostly made of Japanese steel, which means the quality is a little higher than the other steel types.
2. Blade point tip
The pointed blade is the most popular point type for all types of knives. Its advantages are next: it is much sharper than the blunt tip and has bigger cutting power. But the downside is that this tip dulls quickly, and it takes much maintenance. Indeed, that will depend on the blade material
The blunt blade type is common of this type of scuba knife. But many people are mistaken and think blunt mean dull. But the blunt is just as sharp as every other point. Its disadvantage is that it is not quite penetrating as a point, but its advantage is that it is slower dulling and does not require constant maintenance. By the way, it’s pretty good at cleaning fish.
3. Edge types of dive knives
Straight edge is the most common type of blade edge. It is most popular on boot knives. Because its advantage is that it is somehow much sharper than others. It is suitable for cutting food and cleaning fish. You can also easily injure yourself, so be careful.
Serrated dive knife edge
The serrated edge is less popular than a straight edge. Rarely what kind of dive knife has this edge. Its advantage is that it is better at cutting hard or harsh surfaces. And the disadvantage is that it will be difficult for you to cut soft materials. But don’t worry, most of our diving knives have both types of edges on it.
4. Best handle materials
Rubber diving knife handle
Rubber is by far the most popular handle material for scuba knives. The best thing is that it is very comfortable and does not slip out of hand. Of course, there are more good things like low cost, easy to replace and long-lasting. In essence, always choose rubber as a handle material.
Plastic diving knife grip
If you can’t get a knife with a rubber handle, then get one with plastic. Yes, plastic is the second most popular handle material. Not comfortable as rubber, but if you find good quality plastic, then it will be comfortable. It is also very resistant to external conditions, long-lasting and easy to maintain.
Leather and bone
You may wonder why we put leather and bone as a handle materials. Because we want to show you what should not be handle material. The problem with leather and bone is that they are very slippery, they show poorly in the water, and their price is high. So never put these two materials on scuba diving knives.
5. Accessories for scuba dive knife
Each knife comes with some accessories that can help you a lot. Now we will list a few accessories.
A lanyard can be a very useful thing for you. Namely, several knives on the list have a lanyard hole. If you buy such a knife, be sure to install a lanyard. Because it can help you keep your knife safe and reduce your chances of losing.
Sheath for dive knives
The second and most important is a sheath. To clarify something, never buy a dive knife without a sheath. Why you buy a knife when you have no place to put it. You should also pay attention to the sheath material. It should be of plastic, rubber, or nylon. Other materials not. And it must be adjustable, so you can put it on your arm or leg.
