What Sort Of Dive Knife Should You Choose?

When buying a knife for diving, the deciding factor will be the type of knife you will need. In general, most people get confused about whether to go for a blunt or sharp tip? However, you should buy one that has a perfect combination of straight and serrated edges. As a result, you can use it for diving and also as a bottle opener. Besides, based on your comfort level, you can also go for foldable dive knives with a push-button release mechanism. Besides, don’t forget to consider a line-cutting notch feature as this will allow you to free yourself from nets quickly. And don’t go for stainless steel blade knives as they may not last for years under saltwater. 

Stainless Steel VS Titanium Dive Knives

Stainless steel is a common alloy and is widely used in the manufacturing of such knife blades. Grade 304 or Marine-grade 316 steel is used for this. However, in terms of durability, a stainless steel knife may not perform well like titanium, and some of them are not corrosion-resistant. Stainless steel-made knives are good for freshwater. So, most of the experts suggest buying a titanium-made knife as it is durable. They perform much better than steel blades, and also, due to the corrosion resistance feature, they will last for a long time. Such blades are very lightweight and can retain the edges for years.  

Blunt Tip Or Sharp Tip?

Remember that your blade style will play a great role in the overall functionality of the knife. And you need to choose between sharp tip or blunt tip. 

Speaking about a blunt tip style, this is perfect for chiseling, hacking, digging, and prying. Unlike a straight-edge blade with a blunt tip, you don’t have to worry about any accidents, like puncturing your wetsuit, air hoses, and more. Even though such a blade comes with a sharp edge, it is safe to use. 

Now coming to the sharp front edge, it is ideal for cutting and puncturing. Diving knives with sharp front edges are quite popular among spearfishermen. Besides, you can use them to clean a catch. But remember that such a tip can be more dangerous. Furthermore, the tip can break while chiseling and digging. So, sharp tips are not good for scuba divers.  

How Do You Attach Your Dive Knife?

When doing scuba diving, you will have to attach your knife to your equipment, or in your pocket, to your BCD, or your leg. However, the most crucial thing to consider is that you should be able to easily access it. 

Hose Or BCD Mounted Knives

Using such a knife, you can easily and securely attach it to your gear.  Besides, with minimal effort, you can access it. A BCD-mounted knife is smaller and much lighter than other models. 

Leg Mounted Knives

Such scuba diving knives can be a little challenging to use and can also lead to entanglement issues. However, it has been seen that some divers prefer to go for this model to feel like Tomb Raider. 

Foldable Knives

When you have a foldable dive knife, you can easily use them underwater and can store them in the BCD pocket. Furthermore, such products are much safer, and you can’t hurt someone unless it is opened. 

Knife Care & Maintenance

Before You Dive

  • Properly inspect your dive knife for corrosion. Besides, you should also check the locking system and blade.  
  • To keep the cutting notch safe, clean the light corrosion using a toothbrush or a soft towel.
  • Check the sheath for proper functionality
  • To keep the corrosion-resistant, don’t forget to lubricate the lock system. 

After The Diving

  • Rinse your dive knife properly and remove it from the sheath to remove debris. 
  • Dry your dive knife thoroughly. 
  • To maintain its corrosion-resistant feature, you should apply a light coat of silicone. You should not use any petroleum-based lubricant. 

Before cleaning, every user should understand the types of materials used for the blade. In general, a dive knife can come in two major types of materials, i.e., titanium and stainless steel. Titanium-made knives are quite strong as well as lightweight and come with a sharp line cutting notch. But they are a little expensive. On the other hand, stainless-steel knives are very easy to sharpen, and you can get them under your budget. But stainless steel blade requires more maintenance. If you don’t have much time, then buying a titanium dive knife can be a perfect option for you. 

Buying Guide: What to Look For in a Titanium Dive Knife?

Size of the knife

Dive knives generally come under three different size categories. These are large, small, and medium or pocket-sized.  Large knives are the ones that you can see the users wearing strapped to the legs. Well, if you are not an underwater hunter, then don’t buy this knife. As per the experts, most of the diving knives come under the medium-size category. If you are looking for something small and easy to carry, then go for small knives with a drop point tip. If the knives have a serrated back edge, then it will be an added benefit. 


Another major factor to consider is the shape of your knife. For example, you can choose between a blunt or pointed tip. Most recreational drivers prefer to use knives with a blunt tip. Such knives can’t be stabbed accidentally. 

Furthermore, you also need to choose between a serrated edge or a straight edge. It will also depend on what type of scuba diver you are. If you are new to this, go for a serrated edge. Well, it is advisable to buy a knife with a serrated and straight edge as you can use them for different purposes. 

Knife material

You can choose between stainless steel and titanium. For better results, you can go for a knife made of titanium. A dive knife with this material can last for years, and you can use them in place of your line cutters. Stainless steel knives can come with a serrated edge but can retain the edge for years.
