XS Scuba FogCutter X Dive Knife

XS Scuba FogCutter X Knife: A Hybrid Cutting Tool for Recreational Divers

The XS Scuba FogCutter X Knife is not a standard dive knife. It combines a full knife blade with a built-in pair of scissors, making it a genuine multi-tool rather than a single-purpose cutter.

If you dive in environments where entanglement is a real possibility, whether in fishing line, kelp, or loose netting, this is the kind of tool worth carrying.

What Makes It Different

Most dive knives give you a blade and maybe a serrated spine. The FogCutter X gives you a knife and scissors in one sheath.

That matters underwater because different materials cut better with different tools. Monofilament fishing line, for example, is notoriously difficult to saw through with a knife blade. Scissors handle it cleanly. Having both means you are not fighting the wrong tool in a stressful moment.

Beyond the scissors, the back of the scissor blade carries a serrated edge, and the knife includes a dedicated line cutter. Three cutting options in a single tool.

Blade Options and What They Mean

The FogCutter X comes in two tip styles. Choose the one that matches how you actually dive.

• Drop point tip has a blade length of 4.75 inches (12.1 cm) and is the more traditional choice for general cutting tasks underwater.
• Blunt tip has a blade length of 4.5 inches (11.4 cm) and adds a practical bonus: the blunt end can double as a flat-blade screwdriver, which is useful for equipment adjustments on the boat or at the dive site.

Both versions share the same overall length of 9.5 inches (24.1 cm).

The knife blade runs a straight edge on one side. It is not a serrated-spine design, so it is best suited to slicing cuts rather than sawing. The line cutter and serrated scissor spine handle the tougher, fibrous materials.

Steel and Durability

Both the blade and scissors are made from chromate-treated 420-stainless steel. The chromate treatment adds a layer of corrosion resistance on top of what the stainless grade already provides.

420-stainless is a well-established choice for dive knives. It holds an edge reasonably well and resists the kind of surface rust that can appear after repeated salt water exposure if the steel is not properly treated or rinsed. Rinse the tool in fresh water after every dive and it should give you long, low-maintenance service.

Sheath and Mounting

The FogCutter X ships with a sheath and depth-compensating rubber leg straps. The straps use squeeze-style quick-release buckles, so you can put the knife on and take it off without fumbling.

"Depth compensating" means the straps are designed to maintain their hold as water pressure increases with depth, rather than loosening as the rubber compresses. A knife that shifts or slides on your leg mid-dive is a distraction you do not want.

The sheath itself uses an easy-release positive locking system, meaning the knife stays locked in place until you deliberately release it, but comes out quickly when you need it.

Handle and Grip

The handle is shaped to give you a secure grip even with thick gloves on. That is worth noting because many divers in cold water wear 5 mm or 7 mm gloves, and a slim or smooth handle becomes genuinely difficult to hold onto when your dexterity is reduced.

Who This Knife Is Right For

The FogCutter X suits a recreational diver who wants more than a basic blade and appreciates having scissors available without carrying a separate tool.

It is a strong choice if you dive in areas with a lot of fishing line, mooring debris, or kelp, or if you simply want one tool that covers more scenarios than a plain knife.

If you prefer the absolute simplicity of a single fixed blade with no moving parts, the scissors mechanism may feel like more than you need. And if you are looking for a technical diving knife designed for very specific cutting tasks at depth, the FogCutter X is built for recreational use rather than technical applications.

For a recreational diver who wants a capable, versatile cutting tool that handles real-world entanglement situations, the XS Scuba FogCutter X is a well-thought-out option.
