Dive Knife Buyers Guide
What to look for when buying a dive knife
A dive knife will accompany you through all of your diving and snorkeling adventures. It may also be the only thing that you can save you if you encounter trouble within the ocean depths. Whether you get entangled or see an ocean creature imprisoned within a fishing net, having something that can help is priceless.
Possibly the most important thing when buying a dive knife is ensuring that the blade steel is stainless. As well as any other steel accessories that may be located on the knife. This will ensure that your knife doesn’t rust and get weakened. You should still, however, ensure to rinse the knife with clean tap water before putting it back into its sheath. This will prevent any of the potential saltwater getting lodged within the crevices.
Sharp vs. Blunt
The reason a lot of divers use a blunt knife is that you don’t need to pay so much attention to injuring your gear. With a sharp tip knife, you may accidentally cut your hose or suit. Both have their uses, and in essence, it’s good to have both. Most divers have the blunt knife mounted on their forearm for easy general use, and the sharp tip around their ankle. The sharp tip only being used in a real case of emergency.
Sheath & Straps
Most dive knives nowadays come with a sheath and a strap so that you can mount it on your forearm or leg from the get-go. This is a great convenience, and you rarely have to go out and search for these things yourself. When diving, having a reliable knife is almost as important as having a sturdy sheath. After all, what can you do if your straps get loose or unlock and you end up losing your knife?
Now that you have a grasp of the basics, you can go and search for your ideal dive knife. Remember, you should feel comfortable when handling it; a good knife is like an extension of a diver’s arm!
When diving, make sure to strap the dive knife somewhere where you know you can heavy easy access to it. Too often do beginners strap the knives somewhere where it’s impossible to reach them, and get themselves in unfortunate situations because of this.
