Choosing the Best Dive Knife
We call a dive knife essential gear because we view it as a piece of emergency equipment. You need to have a knife in case you find yourself in trouble with an entanglement, whether y line, fishing net or kelp. On top of having a knife for use in an emergency, you may choose to carry a knife for practical purposes as well, such as fishing, hunting or digging. The type of activity you conduct underwater will help determine what type of knife will best suit you.
The most common materials that dive knife blades are made from are titanium and stainless steel. There are pros and cons of each material and price is the most obvious.
Titanium dives knives tend to be more expensive but the also have the advantage of being resistant to corrosion. A titanium dive knife is also lighter than a steel knife of the same size. Lighter knives are great for travel but make sure that if you are traveling by plane that you follow the airlines guidelines of how to pack your knife (usually in stowed luggage).
Stainless Steel Dive Knives are often less expensive than titanium but they need extra care and maintenance. Steel knives do rust and they can do so very quickly if you don’t take good care of them. If you have a stainless steel dive knife you must wash it thoroughly in fresh water every time it comes into contact with salt. It is also a good idea to coat the blade in silicone grease. Silicone grease will help protect the steel from corrosion.
Dive Knife Size
The is a wide variety of sizes available for dive knives. How you plan to use your knife will determine which size is better for you. Larger knives are useful if you plan to use it as a digging or prying tool or if you are diving in areas where there is a greater likely hood of entanglement. Larger knives are also preferred when spearfishing of gathering shellfish such as abalone.
A smaller knife can be useful if you carry it as a ‘just in case’ piece of safety gear. The reason smaller knives can be useful here is that it gives you more options in terms of how you wear it.
The larger the knife the fewer options you have it where you carry it. Typically, large a large dive knife is strapped to the leg, around the divers calf. The issue with this is it becomes an extra entanglement issue if diving in kelp or in area where people are fishing. It can also become cumbersome as an extra piece of gear the must be put on prior to every dive or is easily forgotten.
Smaller dive knives have the added benefit that they can e attached to your BCD or inflator hose so that it is out of the way and never left behind when you go for a dive.
Folding Dive Knives can offer a good compromise when it comes to size. The are similar to smaller knives when folded in that they are unobtrusive and can be kept in a BC pocket. They also have the benefit of a larger blade when they are extended.
You must make sure that you can access your dive knife with one hand, both your left and right. In the case of a folding dive knife make sure you can extend it one handed and that you can remove it from the BC pocket with either hand.
Best Dive Knife Features
Dive knives come with wither a Blunt tip or Point tip, many dive knife models give you the choice of which tip you prefer. Blunt tip knives are often preferred as as they are less likely to cause injury when using it underwater, they are also less likely to puncture equipment such as your BCD or your dive buddy. Latex dry suit seal are particularly susceptible to sharp, pointy knives. Blunt tips can make a more useful tool particularly for digging or prying at things such as shellfish like abalone.
Point tip knives are useful for spearfishing or any activity that requires cutting or stabbing (away from your buddy of course). Specialist spearfishing knives are recommended if that will be the bulk of your activity. A spearfishing knife has a sharp point and a double edged blade like a dagger.
The Edge of dive knife can be either serrated, a non-serrated sharp blade or a combination of both. Serrated and non-serrated blades are good at cutting through different materials. The best dive knife is often one that has a serrated edge on one side and a sharp cutting blade on the other.
A Line Cutter is something that you definitely want on your dive knife. The line cutter is a sharp notch cut into the top part of the blade. It allows you to quickly cut through fishing line or any other thin line that can pose a risk to divers.
A handle with a metal butt can serve as a Hammer and is also useful when using your knife to bang on your tank. Raping your knife against your tank is a great way to get your buddies attention during a dive.
Most dive knives come in a variety of colors, the color is usually visible o the knife handle or sheath. When choosing the color that you want, remember that as a safety device you should opt for high visibility colors over fashion. Bright yellow or lime green are easy to see, especially if you drop your knife or if your buddy needs to locate it on you or your gear.
