Speciality Knives: Benchmade H20 Folding Diving Knife.

Diving knives are specialized tools for a specialized environment. Tomato-peeling sharpness isn’t a prime requirement, and neither is tacticool styling or a narrow piercing point. It’s generally assumed that a good dive knife will have a fixed blade, but that may not be an absolute requirement any longer . . .

A grippy handle, highly visible colors and extreme corrosion resistance are definite must-haves for anyone’s dive kit. Serrations are another must, in case you need to quickly cut yourself free of tangling lines or nets. (Most H20s have them, just not this one in this picture.) A flat or blunt tip is desirable, because nothing says ‘DINNER!’ to marine predators like your blood in the water after you stab yourself.

Benchmade’s H20 dive knife meets these requirements (almost) perfectly, and it’s a folding alternative to the fixed-blade world of submersible cutlery. The 3.4″ partially-serrated blade has a modified Sheepsfoot tip for diminished stabitude, and it’s made from  N680 stainless with superlative corrosion resistance. It’s got the super-strong Axis lock, so you won’t need to worry about it closing on your fingers.

And it comes in this shockingly bright yellow, to coordinate with your other shockingly yellow dive gear.

As a non-diver, this knife would be as useful to me as my very own slotted Absinthe spoon, but Death Valley Magazine posted a users-eye review of this knife a few years ago.

Price: $130

    I am of the opinion that a good diving knife requires a serrated edge at least partially down the blade.

    1. Chris Dumm says:

      You’re totally right, and most H20 knives actually are partially serrated. The picture I scraped from the Benchmade website shows one of the few plain edge versions. Which I agree would not make a very good diving knife.

    I see the Farago influence is at TTAK too!

      What can I say? Early Bond was good cheesy fun.

        We must ban such sexist exploitation of innocent strong intelligent women. 🙂

    there is a knife in that picture? oh wait i see it now.

  4. JAS says:

    What if you want to stab a critter? A BIG one. Big critters don’t like that and just a shallow stab could do it. It could save your life. I can see when that would come in handy from my years underwater. I’ve seen some BIG critters while underwater in the Caribbean and a knife that can stab is definitely desirable to drive them away.

    I do think that underwater knives makers should find a way to make the knives INOX while making the blades black. Anything shinny is also a no-no – ‘cudas love that stuff.

    And she is my all time Bond-girl favorite :).

    The flat/chisel tip has absolutely nothing to do with ‘stabbing yourself’ (my wife is still laughing at that), it’s for *prying* things. Most dive knives have very thick blades for this reason.


    1. Chris Dumm says:

      A diver friend also told me that a flat point is nice to use as an improvised screwdriver when needed.

    My dad carried a flame for Ursula Andress until the end of his days. He had good taste in Bond Girls.

    Calling this Benchmade H2O a dive knife is bordering on the ridiculous.
    A dive knife; a proper dive knife anyway, has always been a fixed blade.
    The blade length should be a minimum 6″ from hilt to blunted tip. This
    is helpful for quick measuring, but mainly because most of the fish in the
    ocean that can seriously harm us are bigger than us, oh, and because all
    saltwater fish have teeth. A dive knife is your fang tooth. Also missing
    from the H2O, and in glaring fashion, is the innocuous, mono- filament
    line hook. Try cutting yourself free from the invisible mono-filament line
    that has entangled you and your rig, without one. I wouldn’t dive deeper
    than 10′ without a knife with a line hook. Neither should you. But above
    all else, if you ever need to deploy your dive knife rapidly, a fixed blade is
    ready to go the second you pull it from the sheath strapped to your leg.
    There’s enough to worry about when you’re at depth, and trying to open
    a folding knife, under water, in a hurry, is just an invitation to disaster.
    If you dive, carry the H2O as a backup…not as your primary dive knife.
