This should be considered an essential safety device as it will provide peace of mind. If something goes wrong and you get caught on something you will be able to cut your way out of it.
When you are exploring the world underwater and need a knife, we understand how important it is to have a reliable one. In a place where you can’t walk to the kitchen to grab another it is important to have the best diving knife on hand. We have done the research to find the top 10 best dive knives of this year.
How To Choose The Best Dive Knife – Buying Guide
As a knife is a crucial safety device to have underwater, it is important to get the best. Best dive knife reviews agree that looking for the following characteristics are of the utmost importance when picking one that is right for you.
Bigger isn’t always better when it comes to the best dive knives. Even though they can range from 3 to 6 inches we find that the 3.5 to 5 inch is the perfect sized blade. This gives you enough travel to easily cut rope or other material and still be compact enough to carry around without too much added bulk.
There are two main types of blade edges. The best dive knife should have both. One side, or part, of the knife should be straight while the other is serrated. If you have to choose between these features look first for a serrated blade. It will be able to cut through tougher material and stays sharp longer.
Normal knifes do not need to stand up to the harsh environment of the ocean. Different material will react with the salt and could cause rusting. We suggest looking for a knife that uses a stainless steel or titanium construction.
The stainless steel option will require regular maintenance and sharpening. A lower number, around 300, will indicate a higher quality knife, but will be harder to keep sharp due to high carbon count. You will have to rinse these dive knives after each use and even apply oil or wax to keep it from corroding.
A titanium blade is a much higher quality and cost knife that requires minimal maintenance. The only drawback to these knives is that they are hard to sharpen but the best dive knives shouldn’t require sharpening that often. This option will not rust or deteriorate over time and will be what you need at all times.
Dive knives can have a pointed or dull tip. Some will appreciate a blunt knife so they don’t puncture things they don’t intend to while others may need that option. New divers may opt for the blunt option as it can be safer underwater.
Most knives will come with a way to attach so you will not lose it. This could be as simple as a loop to allow you to strap it to your suit. Others come with a strap which allows you to attach it to your leg or thigh. This will give you quick access to the knife while having it out of the way. The only drawback is that it could get caught on things.
Q: What Are The Advantages Of A Good Diving Knife?
A: You never really know when you are going to need your knife under the water, and a good diving knife can be the difference between life and death. Having a good knife means having a knife which is strong and sharp. You want the best dive knife which can be easily removed from its sheath and one which is easy to handle under the water. So, what situations could you run into?
The most obvious one is being attacked by a creature under the water. If you are attacked, you may have to fend off the creature, and a good knife is one way to do that. If you are in mortal danger, then you may have to stab a sea creature, and a good knife is one way in which you can protect yourself.
The other situation in which you may need a knife is when you need to cut something. The most obvious occurrence would be when you need to cut some rope or string. This could be as simple as having to cut the line on your dive marker if it has gotten caught, and at themes dangerous, it could involve having to cut yourself free from a tangled rope.
You may also want to cut away coral or open shells with your knife. If you are pearl hunting, then a good knife will save you a lot of time. The best dive knife can make your life easier, and it can get you out of some sticky situations.
Q: How To Take Care Of Your Dive Knife?
A: After having your knife under the water, especially if you are diving in salt water, you should clean your knife. The best thing to do is to rinse your knife under some fresh water and let it dry before putting it back in its sheath. If the knife has any dirt on it, then you should wash the knife with some soapy water (making sure to keep your fingers away from the blade) and then rinse it with fresh water before letting it dry.
If you are putting your knife into storage for a while or you will not be using it for a while, then you should apply some oil to your knife. Find an oil which is specifically designed for use with the best dive knives, although you can also use oil you may have around your house, such as olive oil or canola oil. Make sure to only apply a thin layer of oil to the blade and then play it in the sheath.
You should also sharpen your knife when needed. Check your knife regularly for any chips, and use a sharpening stone to take any chips out and then to sharpen and polish the knife.
Q: Titanium Or Stainless Steel Dive Knife?
A: Titanium dive knives have better resistance to corrosion than a stainless steel knife. In fact, titanium knives are almost rust-proof. There is no carbon in the knife for oxidization. This means that you will not need to maintain your knife as you would with a stainless steel knife. Titanium is also a lot stronger than a stainless steel knife, and it is lighter. Why, then, would you even want to buy a stainless steel knife? Well, stainless steel knives are also resistant to rust, and, while that are not as light or strong as titanium knives, they cost a lot less.
Q: Blunt Tip Or Sharp Tip?
A: A blunt tip is better for a novice diver. Experienced divers are more experienced in the water and have had more time to handle knives. The main reason to have a knife with a blunt tip is to ensure that you do not accidentally stab yourself when you are moving about. A sharp tip is better for experienced divers who want more versatility from a knife. When using a knife in the water, there is a chance that the tip can cut into you, but the more you use a knife, the more your muscle memory will prevent that. We recommend starting with a blunt knife and then transitioning to a sharpened-tip.
