Welcome to Dive Gear Reviews, a comprehensive guide to scuba diving equipment. Scuba diving is an expensive pursuit, so looking up reviews for a particular article of equipment is a wise precaution before investing any hard-earned money in it. However, consumer reviews may or may not be written by an experienced diver, and magazine reviews could be suspect due to the advertising ties of the publication in question. Dive Gear Reviews provides cross-referenced reviews assembled by an expert, making it possible to see at a glance what multiple sources said about a particular piece of scuba equipment. If one magazine loved a scuba regulator or a dive computer, but the consumers hated it, that information will be found here.

The minimum research for a review at Dive Gear Reviews is one review published by a credible magazine, a sampling of consumer commentary from both forums and online retailers, a sampling of pricing and insight from a diving expert. For an entry to appear on this dive knives reviews page, it must exceed that minimum. The reviews below are therefore the most extensively cross-referenced reviews for this type of gear on the website. The complete list of knife reviews at Dive Gear Reviews is available here.

Scubapro Whitetip Dive Knife Review

Dive knife reviews

At only six inches long with a 2 ½-inch blade, the Whitetip is a compact dive knife that could serve as either a primary or a backup tool. The blade has a one-inch plain edge and a one-inch serrated edge, coupled with a blunted safety tip that is well-suited to doubling as a prying tool.

The dive knife’s sheath has a push-button release system that keeps the knife safe and secure, yet allows an easy withdrawal when needed. Scubapro ships this dive knife with the parts needed to mount it on a diver’s console hose or in a BCD pocket in addition to the traditional strap-on mounting on a lower leg or forearm. Scuba Diving magazine described this array of features as “more mounting options than any other knife” in their review of the Whitetip.

The entire dive knife is made of 304-grade stainless steel, with the handle molded over the steel base. As that kind of steel is a soft metal, the blade does not hold an edge well and it will require sharpening after each use. It’s size means less cutting action per pull, so more cutting pulls are needed for each job. However, it is very rust resistant. For this reason, Scuba Diving magazine described it as an excellent backup, but had no comment about the Whitetip serving as a primary knife. Sport Diver was more neutral, describing the Whitetip as a “compact knife blade to be worn on a [BCD] as a primary or backup.” Divers who do not frequently encounter fishing line and electrical wire and who are not laden with gear might therefore prefer to rely on another, bigger dive knife if they are only carrying one blade.

Average Cost: $58


Spyderco Warrior Dive Knife Review

As the name might imply, the Spyderco Warrior is designed as a tactical fighting knife, but in reality the blade is so general purpose that it can function as a knife for hunters, backpackers and divers. If you are an enthusiastic, multi-sport outdoorsman, then this is the blade for you.

The FRN handle with textured scales and full-tang design ensure a firm, solid grip. The curved blade is 5.5 inches long, with a standard edge on the outside of the curve and a serrated edge on the inside, and is made of Spyderco’s H-1 stainless steel. This steel is 100% rust-proof, but tough enough to withstand serious abuse and firm enough to retain a razor sharp edge.

The overall length on a Warrior is 10 inches, so it is not a compact dive knife. Instead, it falls into the category of “hardware tool,” much as the Cressi Orca, except that you can’t really use the Warrior’s butt as a hammer. That lack of a blunt metal pommel or the size may turn off some divers, so it is important to remember what the main virtue of the Sypderco Warrior is: it’s all-in-one nature. This is the knife you use on the boat, for fishing, for camping… for just about anything. It’s the right size, it’s tough, it requires infrequent attention (if it isn’t actually used), and it looks like a mean blade. Scuba Diving and Knife Hog both loved it, and owners of the Warrior give it rave reviews.

Average Price: $200 (a more expensive Warrior Black is also available)


XS Scuba’s Beta Titanium Dive Knife Review

XS Scuba’s Beta Titanium dive knife is a fairly standard-looking dive knife, but its titanium construction puts it a cut above. The Beta Titanium is lighter than a similar steel cutter and absolutely rust-resistant. The 5-inch blade comes with blunt, tanto and pointed tips, and all knives have a standard edge, a serrated edge and a notch for cutting lines. Finally, the locking sheath is considered sturdy and easy to use. LeisurePro users gave the knife a 5-Flag rating, and Scuba Diving marked it as the “Most Bang for the Buck” dive knife in 2008.

Average Cost: $110


Editor’s Mention: Spyderco Mariner Salt Dive Knife Review
Some divers like to announce their pastime through their everyday items. T-shirts are the most obvious, while dive watches are a discrete anachronism that combine style with backup practicality. The Spyderco Mariner Salt is a dive knife that allows a diver to achieve the same sort of identification through their tools. This dive knife is a folding knife made to endure saltwater exposure, but as it is a folding knife, it neatly doubles as a buck knife for carpenters, campers, and just about anyone else who needs to carry a compact knife around with them on a daily basis.

The blade is made from H-1 stainless steel, which uses nitrogen instead of carbon in the steel matrix, creating a nice balance between hardness and corrosion resistance. Scuba Diving magazine wrote of the Mariner Salt that after “a week of repeated dunkings in saltwater without a rinse, the Mariner Salt looked as good as new.” The serrated blade measures 3 ½ inches, and folded the entire package is 4 ¼ inches. Rounding out the package, the knife opens and closes easily with only one hand.

Scuba Diving
magazine labeled it the best knife for traveling divers, and this website labels it as the best knife for a serious diver who wants a high quality tool that can be used both underwater and topside. The one caveat is that it is expensive, so divers should beware of clipping it on their gear the same way they might clip it onto their belts. A diver who loses this knife in a cloud of silt will surely kick themselves over it for months.

Average Cost: $210
