Divers / Dive Knives for Scuba Diving, Snorkeling
In diving there’s no room for mistakes. Knives have always been essential gear for underwater work, whether you’re down there for fun or for business. Divers need knives that won’t dissolve away in salt water and perform equally well in either everyday tasks or emergencies. When seconds mean life or death, buyers prefer knives which don’t fail.
Arriving at the perfect diving knife design isn’t easy. Weight isn’t such a factor in an environment where handle materials buoy the blade and people wear weight belts anyway. Efficiency and reliability do count. In diving knives you’ll find some of the most impressive and most garish modern working blades. Synthetic handle materials — often brightly colored — offer a secure grip and a last chance recovery if dropped. Exotic metals may substitute for the dependable stainless steel most can more easily afford. While a sport diver might be more concerned with redirecting the occasional shark or cutting free from entangling debris, professional divers working in extreme conditions depend on blades that do it all — cut, stab, pry and even saw through cable.
Tailoring the knife to your own level of involvement in the trade is sensible, but don’t skimp.
A Few of Our Favorites
Our pick for the best diving knife is the U.S. Divers Titanium Diver’s Knife. It has the essential features that a reliable diving blade should have, but in lightweight corrosion resistant titanium — better than stainless steel.
Easier on the budget, the DiveMaster Diving Knife shows a similar array of special features with a blade of high carbon stainless steel.
The Kershaw Amphibian Dive Knife is probably the least you should carry. This stainless steel bargain is still a very capable but lightweight blade. Think cutting instead of hammering and prying.

This 3.75-inch blade is composed of 420J2 steel - good for stain resistance and toughness. The amount of time this knife spends submerged in salt water won't quickly spoil the blade quality. It is blunt tip and plain edged, with a serrated spine and line cutter. The blunt ...

This Kershaw Amphibian water sports knife is a bold statement. It's an attractive knife, with a serious and stealthy design, one sure to get some attention from fellow divers and kayakers.
At only 7 3/4-inch total length and weighing in at 3.2 ounces, stored in its lightweight Kydex sheath, this small ...

I have mixed feelings about this Schrade Water Rat dive knife.
First the good feelings: I think the orange nylon handle is attractive, decently sized (4.1-inches), and easy to grip. It is also available in black, which looks good with any diver's gear. The orange, though, makes for ...
Line Cutter

Promate sells all sorts of diving/scuba equipment and accessories - they do not specialize exclusively in knives. This is an important place to start my review because any prospective buyers of the Alligator Sharp Tip Dive Knife, or any knife, should know exactly where that knife is coming from. ...
General Edge Razor Back | Ankle Sheath
Posted by admin
A dive knife only needs to have a certain amount of features to serve its function - I like dive knives with a good straight-edge blade, a serrated section of blade, a line cutter, a tank signal, a convenient sheath, and good resistance against water exposure. This knife offers ...
Sheath, Blue Handle

The U.S. Divers 4.5-inch Sabre dive knife can be summed up into just one word: average. This knife does not have any spectacular features or any significant faults - what you would expect for the price. The Sabre's blade is 420 stainless steel, which is ...
Stainless Steel Blade, Black Handle
Posted by admin
I like the way this dive knife looks. It's important to have reliable gear, but let's face it, scuba diving is a lot about style -- especially for the casual scuba enthusiast. Why else would there be a selection of snorkel and mask colors, or different styles of fin? For ...

U.S. Divers is one of America's oldest dive companies and has been equipping scuba divers, snorkelers, and skin divers with their gear for over fifty years. They know the business of serious diving.

Barracuda Sharp Tip Scuba Diver
Posted by admin
Here's a bigger, badder Barracuda! OK, it's technically not any bigger in size than the stainless steel Barracuda by ProMate, but it's much stronger, and boasts a higher quality than its sibling.
That's because it has a 5-inch blade made from solid titanium, and that's about the best you'll find in a ...
Folding ProMate Seal Diver
Posted by admin
This is a less expensive titanium knife from ProMate, called the Seal. It's less expensive because it's from a low-profile maker and it's a folding knife.
It's give-and-take. On one hand you'd have the strength of a titanium blade in a compact package in your favor. But on the other hand, you'd ...
Barracuda Diver’s Knife
Posted by admin
While this may not be the strongest or sturdiest diving knife available, it's certainly not a bad deal, or a bad product for that matter. The Barracuda would be an acceptable choice to carry with you on your next scuba excursion, no question.
If you're looking for something a bit sturdier and ...
Underwater Kinetics | Blunt or Drop Point
Posted by admin
This is a pretty slick diving knife from Underwater Kinetics (or "UK" as they're known to those in the know).
Diver's knives should be rugged, lightweight, corrosion-resistant and versatile. This knife is all four.
Titanium is generally recognized as one of the best materials for a diving knife since it is ...

Check out the picture of this one. That's a mean looking shark back there.
If you plan to do battle with that dude, I do not recommend you use this knife at all. In fact, if you are looking for a high-end dive knife, this is not it. Perhaps you should consider the ...
Scuba Diving Knife w/ Kevlar Handle

If you're going to come face to face with a shark, make sure you get a good knife, okay?
And if you're going to spend this much on a diver's knife, you'd better make sure you're getting what you pay for.
In this case, it's quite a ...
