Benefits of Having a Dive Knife
So, why do you need a dive knife? There is a common misconception that a dive knife is only for fending off marine animals in case they get aggressive. That is not true.
The main reason why you should bring with a dive knife is to free yourself up in case you ever get tangled. There are so many things in the ocean you can get tangled up in such as a spincast reel or even nets. It is not unheard of for divers to get caught in fishing lines. If you frequently dive in kelp forests, it is also important to bring with you a dive knife to free yourself up in case you get tangled up in seaweed. Rescuing marine life who might get entangled can also be done if you have a dive knife.
It also comes handy during those heavy current scenarios. If you find yourself getting swept away by the heavy current but you can’t find a good grip with your hands, a knife can come handy. You can use your knife to cling to rocks. Stab your knife on a solid surface.
You can also use your dive knife as a tank knocker. This comes handy if you want to get the attention of your dive buddy.
These days though, the popularity of shears and cutters are increasing. Some divers favor these tools rather than the handy dive knife. But dive knives are just as capable of cutting yourself up when getting tangled. Some of these knives even double as spearfishing knives, so if that is an activity you want to do, make sure you get these knives.

What to Keep in Mind When Buying a Dive Knife
Finding a dive knife doesn’t have to be difficult. Here are some tips you should keep in mind when shopping for a dive knife:
1. It shouldn’t be too large.
Of course, you need to make sure it isn’t too big or clunky. You will be bringing other dive gear as well, so make sure you have enough room for your dive knife. About 2-3 inches of dive knife length should be ideal. Also make sure the handles feel compact and light.
2. Make sure the handles are easy to grip and doesn’t slide easily, even when using gloves.
Don’t let your dive knife slip away under water. Make sure it has a good grip and traction, so you can grip it with ease even when you are using diving gloves. Check the handles as well to see if it fits comfortably in your hands.
3. You should be able to mount it easily to your BCD.
Your BCD should have a slot where you will be able to mount your diving accessories and tools. The diving knife you should pick must also have a place where it can be easily mounted to.
4. Convenient features.
One of the features you should look for when buying a dive knife is a locking mechanism in its sheath. You should be able to release the knife with just the use of one hand. While underwater, it can be hard to use both hands just to retrieve your knife, so this feature will come handy.
5. It should be made from durable materials.
You would want the dive knife to last for a long time. That said, make sure you pick one with durable materials such as titanium. Also check its construction. Everything should be firmly placed and that nothing feels like it will come off at any time.
These are the things you need to keep in mind when choosing a good dive knife.
