Though it comes a small package, the importance of knives should not be understated especially in the field of scuba diving. Whether you are a beginner or pro diver, you want a knife that’s sharp, solid, and non-corrosive. If you’re overwhelmed with the wide array of choices, don’t fret because we’re here to help.
When knives are in question, does size matter? Truth is, it does. But don’t get me wrong. Short blades can cut as well as most big blades known to date. The only difference is that bigger blades mean bigger knives. Bigger size equals to bigger handle. Bigger hand, of course, mean better grip.

Check out which knives got a cut above the rest.
Available in yellow, blue, silver, green and orange handles and blunt or sharp tip, the Promate Scuba Diving Titanium Knife features a titanium blade that’s virtually impossible to break. It is also super strong and lighter than stainless steel, providing comfort as you navigate deep down under. The blade also boasts non-corrosive properties, so you can be assured that your scuba knife will stay for long.
Cressi’s Borg is a large, futuristic knife that’s embellished with a solid, tempered blade made out of stainless steel. One side of the blade has straight edges and the other is serrated. But regardless which side you use, both are sharp and very effective for cutting. At the end of the blade is a chisel tip, which enables use of the knife on various operations. This also prevents accidental injuries that are pretty common in knives with pointed blades. The Borg Knife is ideal for scuba divers as well as spear fishermen.
The all-black United Cutlery Dive Knife is designed with sheath, a 4-inch fix blade, and a black uniquely designed handle with 5 holes for better grip and water drain. The sheath itself is impact resistant, ensuring durability with every use. It’s also attached with loops for convenience.
Cressi’s Skorpion comes in 7 different variants – black blunt tip, black stainless steel, black titanium, blue blunt tip, lime stainless steel, white blunt tip, and white sharp tip. This knife is ideal for various applications, including fishing line cutting, pointing marine life, and making hand signals to a dive partner. The Skorpion is a balanced dive knife with a powerful steel blade that comes in either sharp drop or blunt tip. The knife comes along with a sheath, which is equipped with a locking mechanism for quick one-hand release. The sheath is also geared with two knife straps for so you can freely attach the Skorpion to your leg as you dive.
Yet another entry from Cressi is the Lima Tactical Dive Knife. It is offered in three different options – black stainless steel, black titanium, and lime stainless steel. The great thing about this dive knife is that while the blade is quite short (2.95 inches), it comes with a long handle; allowing you to get a comfortable grip for your cutting tasks. It’s also compact, lightweight, and comes with a stylish sheath that can easily be attached to your BCD if desired. It also has a locking mechanism for security. Now, you can effortlessly cut ropes and lines with the Lima Tactical Dive Knife.
Manufactured by Joy Enterprises, the owner of Fury knives, this knife features a 4.5-inch stainless steel blade with razor edge. The handle is covered with impact resistant, soft rubber grip for optimum comfort. Every Fury package comes with a black sheath that comes with a secure locking mechanism. It also includes two leg straps for convenience and ease of transport.
The perfect dive knife, at the end of the day, depends on your preference on materials, length, and other features like edge type, grip, and so on. Whether the knife you are considering is made from titanium or stainless steel, the great thing about knife variants today is that they well-balanced, incredibly sharp, compact, strong enough to resist damage, and can resist corrosion. For stainless steel blades, less carbon content means more resistance to corrosion. But since they are known for their hardness, you need to maintain their sharpness at all costs. Titanium blades are durable and hard, but possibly don’t hold an edge at times like steels with high carbon content. These may also develop rust quickly in salt water.
The key to making your dive knife last is to rinse them off immediately after use and then dry thoroughly. To remove moisture, simply wipe the blade and other metal parts with a soft cloth. Spray the blade with light coating of silicone lubricant and keep in its sheath before putting into storage.
