DIVEIN's take
Why buy from House of Scuba?
House of Scuba publishes a defined return process for eligible items, including when credit or a refund applies and where fees or exclusions can affect the outcome. If you want the retailer's own terms in place before ordering, that is the most concrete reason to buy here.
It also states a continental U.S. free-shipping offer with exclusions, so the order terms are not left entirely to guesswork. That does not guarantee every item qualifies, but the policy itself is part of the buying case.
Worth knowing
Some customers describe friction around returns or refunds, and some also report slower replies or needing extra follow-up when they asked for help after ordering. Read the return terms closely before placing the order, especially the condition, packaging, and fee limits that can change the result.

Quick Facts About XS Scuba Mini Fog-Cutter Dive Knife
- A compact multi-tool dive knife with straight edge, serrated edge, line cutter, scissors, and a blunt-tip screwdriver in one unit.
- The handle releases to become a working pair of scissors, a genuinely useful option most dive knives skip.
- At 6.5″ overall with a 3.25″ blade, it sits low-profile on your gear without bulk.
- 420 stainless steel with a chromate treatment resists corrosion well and rinses clean with fresh water after a dive.
- The blunt tip prevents accidental punctures to your suit, BCD, or hoses while still handling real cutting tasks.
- Ships with a locking sheath and mounting hardware that fits a BCD or a high-pressure hose.
- A solid pick for recreational divers who want one compact tool that handles most underwater cutting and rigging needs.

XS Scuba Mini Fog-Cutter Knife: Compact Multi-Tool Dive Knife
The XS Scuba Mini Fog-Cutter Knife is a small, multi-function cutting tool designed to mount on your BCD or high-pressure hose and stay out of the way until you actually need it.
If you are a recreational diver who wants one compact tool that handles more than a plain blade, this is worth a serious look.
What It Does
Most dive knives do one thing: cut. The Mini Fog-Cutter does several, and that is the whole point of the design.
- Straight edge on one side of the 3.25-inch blade for clean cuts through webbing, plastic, or soft material.
- Serrated edge on the other side for tougher or fibrous material like rope or kelp.
- Line cutter built into the tool for quickly dealing with monofilament or thin cordage without needing to position the full blade.
- Scissors released by unlatching the handle, useful for cutting material where a blade would be awkward or unsafe.
- Blunt tip that doubles as a flat-blade screwdriver for minor equipment adjustments.
The blunt tip also means you are not carrying a point that can accidentally puncture a drysuit, a BC bladder, or your buddy.
Size and Mounting
The overall length is 6.5 inches (16.5 cm), with a blade of 3.25 inches (8.3 cm). That puts it firmly in the compact category.
Compact matters because a knife you actually mount and carry is more useful than a full-size one you leave in the bag. The Mini Fog-Cutter ships with a sheath that includes a hose mount adapter and straps, so you can attach it to a BCD D-ring, a low-pressure inflator hose, or similar anchor points on your setup.
The sheath uses an easy-release, positive-locking mechanism. That means it will not shake loose during a dive, but you can draw it quickly with one hand when you need it.
Blade Material and Care
The blade is 420 stainless steel with a chromate treatment for rust resistance. Saltwater is hard on metal, and 420 stainless is a practical choice for a dive tool: it holds an edge reasonably well and is straightforward to maintain.
Care is simple. Rinse with fresh tap water after each dive and the chromate treatment does the rest. No special products required.
Who This Is For, and Who It Is Not
The Mini Fog-Cutter suits a recreational diver who wants a low-profile, versatile tool rather than a dedicated cutting blade. If your priority is a large, heavy-duty knife for serious underwater work, the compact size and multi-tool design are not what you are after.
It is also a practical choice if you already carry a primary knife and want a small backup tool with added functions, mounted somewhere accessible like a hose or chest D-ring.
The scissors function in particular is genuinely useful for entanglement situations where you need to work carefully around thin line without a full blade sweep. That alone separates this from a standard dive knife.
