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.
