Is this the best scuba diving knife? Let’s find out… As an avid diver, it’s important that all my safety equipment is of the best quality. This is why I’m always on the lookout for new diving equipment that will serve me best at sea. For six months now, I’ve been using the Promate Scuba Dive Snorkel Titanium diving knife, recommended by a good scuba-diver friend.
What it Looks Like
There are actually two versions of this diving knife: one with a blunt tip and another with a sharp tip. I currently own a dull-tipped version in yellow. The blade itself measures 4 3/8 inches and is made completely in titanium. The handle is rubber and molded into the knife. It comes with a sheath and adjustable straps for fitting. This lightweight knife has an ergonomic design and comes with a hammer nub at the bottom.
Use and Durability
At first I wasn’t too happy about the bright yellow color of the blade. Later however, the color proved useful because you can easily see the knife underwater. I was also amazed at how light the blade was, making it effortless to use the tool when we’re several feet below the sea – that’s the joy of a titanium blade. In my opinion however, what makes this the best diving knife so far is the low maintenance. Even with daily exposure to saltwater, the titanium blade remains clean and rust-free. Maintenance is simple enough – all you have to do is wash it in freshwater and let it air dry.
Blade Handling and Security
The handle is strong and sturdy with a design that fits perfectly in my hands. I’ve also tried using the sheath above and below water to test its lock and release function. Both times, the diving knife performed beautifully with a secure lock that snaps that blade into place and keeps it there. If you need to use it, a simple pulling motion removes the blade from its cover with no resistance at all!
Blade and Edge
I know I’m not supposed to do it, but I also wanted to test the strength of the blade on other materials. First, I tried cutting a typical rope and then chopped off small bits of wood. The blade managed to perform beautifully both times and still managed to retain its edge. After six months of use, the blade is still pretty good. Is it as sharp as a steel blade would be? Possibly not, but the advantages mentioned above of titanium mean I am happy to sharpen and use for another six months.
The strap is the only part of this blade I’m not too keen about. It’s made from rubber and adjustable, but a little too small for the thigh if you’ve got big legs. It can be adjusted to fit perfectly in the calves however which works well for me. The rubber material is thick and ties securely to the skin, perhaps capable of lasting for a few years.
So far, the Promate Scuba Dive Snorkel Titanium Knife hasn’t failed me yet and I look forward to using this blade in the long-term. I’m thinking of buying a sharp-tip as well since the blunt-tip worked so well for me. Considering how much I paid for it, this can be the best diving knife within the affordable price range!
