Diving Knives


What is a Scuba Dive Knife?

A scuba knife is a tool designed for divers to take with them underwater. Sometimes preferred by those diving in order to hunt fish, it is also useful in emergencies.

Scuba or diving knives can be carried underwater without being damaged. They’re designed to resist rust and corrosion even when exposed to salt water. They are often carried in a leg strap to make diving with them easier. Leg straps also allow the diver to swim with the knife on their body, easily accessible but never in their way.

How are Scuba Dive Knives Used?

Scuba dive knives are commonly carried by divers for safety and emergencies. A typical scuba dive knife isn’t going to ward off a shark, but it will free a diver if they accidentally get entangled in something while underwater.

Scuba dive knives are essential because of how perilous diving is as a sport. While underwater, others can not hear you and may not even be able to see you. With communication severely limited, emergencies are even more urgent. It is easy to get tangled in seaweed, netting or other debris underwater. It may not be possible for someone else to help the diver, even if they do see that they are caught. This has made a scuba dive knife an essential safety tool.

But diving knives have uses beyond just safety. Many people who go spear fishing also carry a dive knife with them. This knife is similar to the ones used just for diving and not hunting. However, sometimes those who are using a dive knife for spearfishing choose a larger, sharper knife. A more compact knife is fish for cutting through entanglements, while a larger knife is necessary for actual hunting.

The Best Scuba Dive Knives for Diving

When it comes to a diving knife for scuba, there are a few criteria to keep in mind. A good scuba dive knife shouldn’t be too large. It’s tempting to get a huge knife that you feel like you could take down a shark with, but that won’t actually serve you well. A more compact knife will be more efficient, and more mobile in the water, where swinging a knife feels different.

You should also test how the knife feels while you’re wearing gloves. Usually, you will have gloves on while scuba diving, so being able to grip the knife even with gloves on is crucial. Beyond that, it’s essential that the knife has a superb grip all around, as you’ll be wielding it in water where grip is much more difficult. Good scuba knives are designed to be easy to hold even in these tough conditions.

Also check the way the knife is meant to be worn. You’ll need a knife that is easy and comfortable to wear and move around in, but also within reach at a moment’s notice. Scuba knives need to be extremely accessible to the person wearing them. This allows for quick access in the event of an emergency under the water.

Finally, look for scuba knives made of titanium. This is the best material for a knife that is going to be in water, and salt water, fairly often. Titanium can stand up to the stresses that come from the environment during a dive.

With all this in mind, don’t forget to think about your personal comfort. A scuba knife is only useful if it is comfortable and accessible for the diver. If a knife feels easier to carry and wield, but perhaps isn’t “perfect” in other ways, it will serve you better than a knife that is not suited to you.

Do You Need a Leg Strap with Your Scuba Knife?

Not everyone uses a leg strap with their scuba knife but it is highly recommended. There are many other ways to carry the knife, however.

The leg strap is a secure and reliable way to carry a scuba knife. Many divers use leg straps and have been for a long time. They are often outfitted with industrial strength velcro in order to make the straps both strong and adjustable. Velcro straps also allow you to position the leg strap exactly where you want it on your leg. Often, people carry the knife on the same leg as their dominant hand. So if they right-handed, for example, they will have a right side leg strap to make getting to the knife as easy as possible. You wouldn’t want to grab the knife and then need to switch which hand it’s in.

However, there are many other options when it comes to carrying your diving knife. Some people strap it to their ankle. This is actually a very traditional way of carrying a scuba knife and has been used a lot. However, this worked better in the past with very large knives. It’s not as practical in modern times with sleeker knifes.

One of the most popular ways of carrying a scuba knife is somewhere on the BCD. It can be attached to the low-pressure inflator hose, in the BCD pocket or simply attached to the BCD. Many BCDs even have features designed for easy knife carrying.

Titanium and Folding Diving Knives for Scuba

We carry a range of diving knives, including some that are foldable. Folding diving knives allow for even easier carrying, as they are exceptionally compact. It is the best way to carry a diving knife if you want minimal weight and bulk on you while you’re diving.

We also have high visibility knives, to make you and your knife easier to spot under the water. The underwater world can get murky, dark and confusing, so increased visibility makes everything easier.

No matter what the specific style, many of our diving knives come with straps that you can attach wherever you prefer. This makes your diving knife easy to carry no matter what situation you’re in. You’ll always be able to reach your knife easier and use it at a moment’s notice.
