Well, I don’t really need a dive knife, but I do need a corrosion resistant knife for taking out in the ocean. I’ve got a sailboat and an ocean kayak that I use for lobster fishing. The lobster nets in particular has a ton of lines that could get tangled. After my Leatherman Wave got rusty due to less than meticulous care, I’m thinking that I’d like to get a titanium or ceramic knife.
Is it dangerous to have a pointy knife strapped to your arm or thigh? It would be cool to have the quick release mechanism should I get attacked by an agent from KAOS or have to wrestle a shark. Do the quick release mechanisms work reliably over time, or do they get worn out? Would the sheath stay in place even while moving about on a small catamaran? Is it a good idea to get one with a blunt tip, as to not impale oneself? It would be nice to have a line cutter built in. The knife should be big enough to chop up a frozen mackerel for bait. Cheaper would be better, as I have a tendency to misplace such items and also there is a reasonably good chance of dropping it into the water.
