Spyderco SALT Dive Knife

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.
