Today I want to recommend you a beautiful tool for your diving experience that is quite multifunctional and handy.It is a perfect accessory for any kind of underwater sea emergency situation.

This knife has a full length of 9.5 inches, with a 5-inch, 1-piece blade that is made from titanium, and a sturdy and sleek tang. With its nice serrated top surface you can cut through many tough materials. The bottom part has a main blade with straight edge along with a decent line cutter.

One of the most important characteristics is that you do not need to wonder how to wipe the scum from the junction between handle and blade that is usually difficult to reach. This knife you can disassembly completely with no extra efforts.

As an experienced diver, I would love to take my dive gear and scuba to the fresh water lakes that are full of wonderful aquatic life. Here I get access to a whole new range of opportunities, of new worlds of underwater beauty. Yet there should be certain precaution of altitude diving as it is quite a different atmosphere for a human being, the way we breath and the air pressure is different.

Usually we refer to certain decompression tables for our diving. Yet they may become highly inaccurate in terms of altitude diving. The tables deal with controlling release of nitrogen absorbed at the time of dive, yet at the condition that you dive at the sea level, at normal atmospheric pressure.

As soon as you climb at about one thousand feet above the sea level, the pressure goes down, so the conditions are significantly different for your human organism, so you need to account for them. Altitude diving is basically any diving that is done at the height of one thousand feet above the sea level or higher. If you do not follow specialized procedures, you fall at risk of decompression sickness.

Actually the data for altitude diving is relatively scarce, so the attitude should be more conservative. You should follow the procedures with utter attention.

Sometimes two different situations of altitude diving and flying after diving are confused. As far as flying after diving is concerned, we speak of either single dives (requiring  minimum preflight surface interval of twelve hours), repetitive or multiday dive (minimum eighteen hours of surface interval), or those requiring decompression stops (more than eighteen hours). So at flying after diving your exposure to lower pressure actually follows diving, but at altitude diving this exposure precedes diving. So you should never apply the same procedures at these situations.

Also be careful when diving at one altitude and then diving at yet higher altitude. There should be different procedures for both kinds of diving. We will dive into altitude diving more elaboratively soon. Stay tuned with us, and do not forget you diving knife or titanium diving knife with you.

Diving Knife

Diving knife can be made of different materials, and can vary in size or shape. Yet you have to remember that your knife is not a weapon but only a tool. Let us list a few tools that will help you to make a good decision on what type of knife will be the best option for your needs.

As far as size is concerned, large knives are defined as having a blade longer than five inches. There is a common misconception that the large the knife the better. Yet it can either cut you or your buoyancy control equipment. And be an awkward burden in a situation that you want to get rid of any unnecessary weight.

Medium sized knives have blades of four-five inches and are the most practical ones. They can be easily mounted on the BC, leg or arm. You can grip this knife securely and manage it as a handy tool underwater. If you buy a mini knife with two or three inches of blade, make sure that its handle is longer than three inches. Otherwise it can harm your hands or gloves if you wear them underwater.

The shape of a diving knife varies, too. It can have straight edges that is useful  for cutting plastic. This includes monofilament fishing line, as well as nylon rope. Diving knives with serrated edges are useful in cutting kelp and natural fiber rope. In this kind of knives serrations should run along almost whole length of the blade, so that it can produce a decent sawing motion. Many knives have both edges, staight and serrated, so you can use them in almost any situation.

Sometimes they have sharp tips that can be used for spearfishing, and blunt tips for prying, hacking, chiseling or digging. Sharp tips can potentially harm your BC, so you can use a blunt tip instead. For cutting small lines you will need a knife with a line cutting notch.

Many diving knives are made with 300- or 400-series stainless steel alloys. Due to high carbon content many stainless steel knives show signs of rust. Thus they require some maintenance: rinse your knife well with fresh water and dry outside of sheath. Then you coat it with a light layer of silicone or oil.

As far as 300-series or 400-series allow, the lower the number, the more corrosion resistant this diving knife becomes. Yet it is less capable of keeping a sharp edge. You spend less time on its maintenance but need to sharpen it after two or three dives.

Titanium knives are rustproof  and corrosion resistant. They do not contain any carbon. Thus you do not need any sharpening or maintenance for a long period of time.

There are a lot of manufacturers of diving knives, such as Aeris, Aquatec, Akona, Armor, Deep Outdoors, Cressi, Cutterfish, Deep See, Dive Rite, Innovative, Mares, Max., Oceanic, OMS, Promate, Zeagle and more…

When you have a mask, a snorkel, and a pair of fins, you bet you can engage in snorkeling. Even though price ranges for these can vary a lot, the most valuable advice you get is keep it fit and comfortable, that is all. If your mask does not fit, it will perpetually leak, and that is annoying indeed for your otherwise enjoyable dive. The same applies to fins that can rub ray spots on your feet. Expensive equipment does not necessarily mean more comfortable, so take your time and shop around until you find your best gear (and diving knife).

Many certifying agencies offer classes that you can buy through your diving shop. The matter is of course you can learn snorkeling yourself; yet taking classes shortens learning time and increases your self-confidence.

Your eyes are made for the air, so they just do not operate so well in their unnatural underwater environment. Things look blurry in the water. The solution is a diving mask that creates special space of air before your eyes, and also keeps water out of your nose. At the time of diving water pressure outside increases as you go deeper, and your diving mask is pushed toward your face. It is known as mask squeeze. To equalize the pressure and get rid of uncomfortable mask squeeze you must be able to breathe air into your mask with your nose. Independent of mask style and brand, make sure it protects your nose as opposed to swimming goggles.

A snorkel is a hollow tube which allows to breathe when your head is under the water surface. Modern snorkel includes nice materials, wrap-around design, comfortable mouthpiece and sometimes a splash guard and a purge valve. Every year you find more and more sophisticated models of this simple device. The most important thing about a snorkel is its comfort for your breathing.

Fins help you to propel in the water, and are divided into two categories: full-foot and adjustable. Full-foot ones unclose the hill about the same way as a pair of shoes does, and many people choose this type for snorkeling. These fins are quite flexible as opposed to adjustable fins, and easy to use for swimming on the surface.

Adjustable fins are used often in scuba diving. They have open hill and an adjustable strap. They are great when the water is cold, because you wear a bootie for your feet protection. But many divers prefer this type for warm water as well.

Diving knife is yet another not necessary but sometimes very useful type of gear meant mostly for diving, but at times for snorkeling too!

Once you have your decision about size, general style and cost of a knife for scuba diving, you need to consider other important factors. As far as cost is concerned, you choose between expensive titanium diving knife and its steel cousin which is half the price of former. The titanium one does not rust, and steel has this unhappy tendency. Titanium diving knife is also lighter and stronger, even though that is not necessarily important for a diver.

Well, if you are a seasoned diving fan or plan to practice this kind of sport for years to come, then your choice number one is a titanium knife, an investment that is well worth your money and a source of your pride when other scuba divers in your boat have measly old rusty steel dive knives. Of course, for once in a year occasion the material of your knife is not much of an importance.

Consider choosing a good sheath for your knife, otherwise it will fall out during your first or second dive. Even if you had a gold one with gems, if you lose it, there is no use, whatsoever. Make sure there is no way your knife slips out of the sheath. It is great if it clips in flush, and you also need a simple way to put it back when you are unable to see well underwater.
Then what edges does a good diving knife have? Usually it is a standard smooth blade, a serrated blade that is able to cut through things without applying much downward pressure, and a net cutter. If you have to cut strong materials, consider buying some trauma shears.
There are different kinds of attachments for knives, some have only straps, and others have everything imaginable. If you are not sure what you need, get a knife with many options like a T-Rex knife from Lumb Brothers.
Always check whether it is comfortable for you to reach your diving knife without straining yourself. Some difficult zones include your leg and one of your arms that could be snagged with no way to get the knife when you utterly need it. So one of the best places to put your dive knife is on your BCD.
So if you need a great knife for your scuba diving needs, go get a titanium one that has good accessories and is reachable on your body.

Many nondivers believe that diving is only for tough men, barnacle-backed mariners. But it is not true. Actually diving is more of a pastime than even a sport. Usually it is not more strenous than taking a walk or driving a car to the convenience store.

We do not intend to persuade you that diving is lacking risk. It is a visit to another world that could be really dangerous at times, even to the extent of being fatal if you do not respect its natural laws. But generally statistics tell that driving is more dangerous than diving.

This undersea world functions according to some definite, predictable physical laws. They are not too complicated to comprehend, and realizing them, knowing them thoroughly helps you to function in the watery world, and helps you get rid of ungrounded fears.

Diving is divided into two somewhat similar activities: scuba diving and snorkelling. Snorkel is a plastic tube that extends along the side of your head and above the water, to provide you with fresh air while you float with your face under the water. You also wear a diving mask, a watertight airspace in front of your eyes, with a window for observing the beautiful underwater world. You also propel yourself forward by kicking a pair of fins that are attached to your feet. You do not need much gear, to name diving knife as one of the accessories.

Free diving means filling your lungs with air and dive below the surface holding your breath and looking for underworld mysteries until you need more fresh air, and you return to the surface.

Many people start snorkelling by going to Caribbean or Hawaii on vacation, they rent the gear and wade out in clear water. Snorkeling does not require a lot of training, and it is a good way to find out whether this kind of pastime is right for you, before you spend a fortune on scuba lessons and equipment.

There is a natural development from snorkeling to scuba diving, and many divers started with snorkel and diving mask. Scuba is an acronym for Self-Contained Underwater Breathing Apparatus. You basically wear the same gear as snorkelers do, but take along a bottle of compressed air and a few mechanical devices that facilitate breathing from the bottle, a vest can be inflated with air or purged to adjust your buoyancy, and gauges to monitor air supply. As you stay underwater for a long time, you need some more extra gear, like a diving knife, for example.
