Specialty Knives for Scuba Diving

It is not only about having a good specialty knife for scuba diving, it is also about having the one that fits your needs and goes well with your gear.  As a scuba diver, you know the importance of carrying a good knife with you during your adventures. They are a necessary gear if you want to make your experience a pretty good one.  Let’s briefly discuss what are some the best specialty knives for scuba diving.  From there, you can make a decision on which ones would you like to get for yourself.

But before we do that, let us delve into what must you look for in a knife.


Picking the best material can be a tricky task since there are certain aspects that you need to consider.  Alas, you might not find a knife that meets them all.  A knife made of titanium or other specialty steels will strongly resist corrosion but will not have the resistant required to keep it sharp.  A stainless steel one, on the other hand, guarantees and edge but will corrode more easily in salty waters.


The size of the knife you want is important.  A large knife might be best for a better grip, but a small one will cut just as well as a large man.

Rust resistant

Titanium and some steel alloys provide a great resistance to corrosion.  It is, however, important that you take special care of your knife to prevent corrosion.  Rinse your knife right after getting out of the ocean with clean water making sure that you remove all salt remains in it.

Blade design

This largely depends on what you are going to be using your knife for.  Make sure that your knife has a good hand grip and that you will safely keep it without falling.  If you are going to be performing activities that require heavy cutting and sawing, go for a rugged knife, with a thick blade, and great grip.  If you are taking one just for small emergencies such as cutting off alga entanglements, then you can go for a more compact one.  You might feel tempted to getting yourself a foldable design.  This is all right but keep in mind that most foldable knives will require you to use both hands to open them.  Attempting this with one hand might pose a cut hazard on you.

Now, these are some general designs that you can choose from:

Pointed Tip

Use this knife for spearfishing.  They are usually thing and easy to carry.  Just make sure you do not pierce through your equipment with it.

Blunt Tip

These are more suitable for prying and digging.  It is, of course, safer than the pointed tip as there is no risk of puncturing the diving gear.

Compact or BCD

These can easily be attached to a BCD or a hose.  They are very practical, especially when traveling.


Use these to cut through algae or plants. They are the best for precise cutting underwater.

If you want to get the best specialty knives for scuba diving and the best snorkel gear, look for the professionals and the best retail seller.  Think of your satisfaction and your safety.


Tactical Knife Buyer’s Guide

Nowadays, there are so many tactical knives available in the market, making it hard to choose the right one. If you’ve tried shopping for one, you’re surely going to have a hard time making the right choice. If that’s the case, then remember that features are the most important thing that you need to consider when buying a tactical knife, not the appearance, brand (though choosing a well-known high-quality brand can be very useful) or coolness. You can also take a look on the specifications, though this requires a good understanding of tactical knives. But setting everything aside, the most important thing is that your tactical knife can do its job right and flawless.

Types of Tactical Knives

There are two main types of tactical knives – they are fixed and folding. When buying a tactical knife, it is important to determine your purpose for them to make sure that they can do their job easily and perfectly.

Folding Knives – are also called pocket knives. There are different kinds of pocket knives but the most common are: single, double, multi and Swiss army knives. They vary greatly in shape and size.

Fixed Blade Knives – are stronger and more durable compared to folding knives. They are also stronger and thicker. Like folding knives, there are various kinds of fixed blade knives, some of them are:

  • Hunting/Camping Knife – as the name implies, they are primarily used for hunting purposes such as skinning, boning, gutting, cleaning and stabbing. They can also cut through ropes, camping food, etc. with ease making them a great camping utility.
  • Skinners – they often have short but very sharp blades.
  • Gut-hook – if you’re hunting an animal, it’s the perfect tool to carve a hole through its belly.

If you are looking for a survival knife these are also some of the important things to keep in mind.

  • Full Tang – yes, they are great thirst quencher, but we’re not talking about the juice drink here. Tang is the part of the knife that extends to the handle. If you removed the handle, you can see a smaller piece of steel extending towards the handle for gripping, that’s the tang. Generally, a full tang knife is sturdier than other tang types, which makes a full tang the strongest in terms of cutting and stabbing.
  • Solid Pommel – the handle’s butt. A solid pommel can be used to hammer things down in case you forgot to bring a hammering tool. But there are other kinds of pommel that can store sticks, matches, etc. which provides additional survivability tool, but they can break easily when used as a hammer.
  • Knife point – pick a pointed knife which will make poking at things easier.
  • Edges – there are two types – the single and double-edged blades. A single edged blade is safer to use than a double edged blade, unless the double edged blade features a sharp and serrated edges – making it highly flexible.

What is Tameshigiri?

Have you heard about Tameshigiri? If you are a fan of swords, especially Japanese ones, you must’ve heard of it. Tameshigiri means test cut or the art of cutting, literally the art of test cutting. It became popular in Japanese Edo period as a way of testing a sword’s quality. However, as time passed by, Tameshigiri became a martial art, which, instead of focusing on the sword quality, it focuses on testing the skill of the cutter. Let’s delve deeper and learn more about Tameshigiri.


Origin of Tameshigiri

During the Japanese Edo period, swords were tested by sword masters for their quality. It is important to note that only chosen swordsmen were allowed to test the swords to make sure that it is indeed the sword was being tested and not the cutting skill of the wielder.

The materials used for testing varies greatly during that time. Some of the common materials used were wara (rice straw), goza (top layer of tatami mats), bamboo and thin steel sheets. A well-crafted sword should be able to cut these materials with ease.

However, those cutting materials weren’t really the center of attention for sword testers. The most popular testing material was a human cadaver, especially of a convicted criminal. Yes, you read that one right. When a sword is tested using a human cadaver, they would acquire a “saidan-mei” or cutting signature. Nowadays, there are still swords marked on their nakago (tang) which says things such as “5 bodies with Ryu Guruma (hip cut)”. Take note that those inscriptions greatly add to the value of the sword.

However, not all human cadavers can be used as a test target. As you may have known, the Japanese are very ritualistic, and thus, they carefully inspect each cadaver for any signs of diseases or any signs of diseases. In addition to that, they don’t use bodies of lower caste or of priests because they believe that it will warp the blade’s soul.

Modern Usage

With the reformation of the Japanese law, Tameshigiri slowly removed and ultimately banned the use of human cadavers. It’s replaced by wara, which is proven to be of the same consistency and density as the human body.

Then, moving on to the present day, Tameshigiri changed from being a way to test a sword to being a way to know how skillful a swordsman is. Modern targets are usually tatami omote (which consists of the outer covering of a tatmi mat popular in Japanese homes), also known as goza or wara. They are bundled or rolled into a tubular shape – and can be soaked to add density. The additional density makes it sure to have approximately the same density as of human bone and flesh.
