What to Look For in a best dive knives?

Sometimes, purchasing a product can draw some difficulties for shoppers, and that's why you shouldn't waste your time on unreliable sources of information. A variety of variables impact the best dive knives, along with all of the ones listed below. The formative assessment varies depending on the types and functions of the product. 

We will give you some purchase guides to help you with your selection proc in the following sectors. Continue reading to learn about what you should look for when looking for the best dive knives: 

Blade Size

Your dive knife will most likely be used underwater so it needs to be easy to open and use. It will be much easier to use a small knife underwater than a larger one.
A dive knife's blade should measure between 3 and 5 inches. A blade that is more than five inches in length can make it difficult or dangerous to use underwater. Blades of 3 to 5 inches are not likely to work underwater.
To be effective and most easy to use, a diving knife blade should not exceed 3 inches in length but must not exceed 5 inches.

Blade Material

The knife blade will rust easily from saltwater and sand. The knife blade must be capable of withstanding saltwater submersion without becoming rusty. Titanium and stainless steel are the best materials to resist corrosion and rust.
Titanium is more resistant to corrosion and rust than stainless steel. You will need to clean stainless steel after every dive, as saltwater and sand could quickly corrode the blade and make it dull.
Titanium has a higher resistance to corrosion and rust than other metals. Although titanium may be more expensive upfront, the rewards will outweigh it.

Blade Edge & Tip

Diver knives can be purchased with either straight or serrated cutting edges. For cutting through dense materials and sawing, serrated knives work well. Straight edges can be used for more precise cutting.
You can find dive knives with both blunt and sharp tips. The blunt tips of dive knives are very useful for prying or digging. Because you don't want to accidentally poke anything, blunt tips can be useful when working in tight spaces. The cutting edge of sharp tips curves towards the end and has a very long length. They are useful in any circumstance where the horizontal cutting edge is not possible. Tanto blades are also worth mentioning.

Attachment Features

You will have to attach the dive knife to your body in some manner. You can attach the knife to your body with straps, a belt, a lanyard or pocket clip.
Straps are the best way to attach your dive knife. The sheath will have two straps, one at the handle and the one on the blade. For quick access, this will ensure that the sheath is securely attached to your leg.
You can attach the knife to your body via a lanyard, tether or rope. The lanyard can be held by string or rope to ensure it does not sink to the bottom.
A locking mechanism is another feature that may be found on knives. This will ensure the knife stays in its sheath. It is essential as this will protect the knife against accidental fall out of its sheath when diving.

Visibility

Diver knives can often come in brightly-colored designs. The knife was not designed to be worn with your swimming trunks, contrary to popular belief. Bright colors can be easily seen if your knife is dropped while you dive. The same rules apply if you are in need of a knife during an emergency.

Foldable Or Fixed

You have two options for the dive knife: foldable and fixed. There are many benefits.
The use of fixed knives is very simple and quick. You can simply remove the fixed diving knife from its sheath and you are ready to go. This is a quick and easy process.
While folding knives can be difficult to open, it is possible to store them more conveniently. Because they are much less likely to be damaged or lost, folding knives can also make diving knives safer.
Both fixed and foldable dive knives can be used effectively and are both sufficient. However, each has its own benefits.

FAQs

What Type Of Dive Knife Should I Use?

Divers can choose from a variety of knives, each with a different purpose. A combination of a regular and serrated knife is best for cutting tough ropes like those used in fishing nets. This knife can also be used to cut thin fishing lines with its line-cutting notch. Consider what type of diving you do before you purchase a second blade. A stiletto knife is useful for spear fishers as it will quickly kill the catch and keep them from being spooked by predators. You can purchase more durable blades that can be used for different tasks, such as sawing and prying.

Can I Use Dive Knives Against Sharks?

It is crucial that you don't provoke underwater predators like sharks or barracudas when you dive. They won't attack you unless you feel threatened. If they do, they will most likely snap at your face and flee. The water pressure in depth can make your movements slow and clumsy, making it very unlikely that you could use your knife to defend yourself against the lightning-fast attacks of underwater predators. Even if you were able to fight back, it would make matters worse since more predators would be looking for blood. You need to be able to safely dive with sharks. If the situation becomes dangerous, it's time to get out of the water.

Should I Choose A Black Blade For My Dive Knife?

Divers can also be attracted to or scared off by shiny knives. This will usually not cause any problems as your knife will stay in its sheath. If you plan on using your knife frequently, you may want to opt for a dark blade. This will prevent you from being bitten by any underwater predators. A black knife is more difficult to find than shiny metal ones in case a diver drops it.

Are Knife Straps That Go Around Your Leg Safe To Use?

The knife should be low-profile and flush with the leg. Most experienced divers prefer to place their knife inside the leg, particularly those diving in wrecks and other areas susceptible to entanglement. This will keep the knife in between your legs and prevent it from becoming entangled. You can attach smaller diving knives to your BCD/inflator hose, so you are able to reach them more quickly if they get caught up. Divers often carry more than one knife or cut tool, with one attached to the BCD and one for the inner leg.

How Do You Care For Dive Knives?

They are strong and will last for many years if they are well maintained. Soak the sheath, strap and knife in cool water after every dive. It will remove any grit, salt or chemicals that could cause damage to the material. Before you store it, dry everything completely. Use a bit of silicone oil to coat the knife. If you've been using the knife a lot, it may be necessary to sharpen it before storage. Sharpening knives is an excellent idea after each dive to ensure they remain sharp for your next diving trip. Keep knives out of reach of children.

How Many Knives Should I Carry?

Two knives are a must for experienced divers. In case one or both of them get lost, it is a good idea to have a second knife. One knife should be within reach of you right hand, such as your inflatorhose. The other one should be within reach of your left (such like your BCD waistband or weight belt). You will be able reach the knife you need even if your arm gets caught up. Do not carry too many knives. This can make you feel awkward and could lead to weight gain.
