Dive knife recommendation?

[Mecha]

Ocean Master knives. These are some of the best knives for this purpose hands down. Reasonably priced too.

Lapedog no offense, but I thought you said you've never owned a cheap ti dive knife like an oceanmaster. Seems like you keep pushing them for some reason. The cheap ti dive knife genre are some of the worst knives I've ever seen, frankly.

OP I think you'd be way better off with a good stainless steel serrated blade like others recommended, or a tungsten carbide edged ti knife like one of Daniel Fairly's little backpackers. Tungsten carbide edged ti cuts rope and fibrous materials well.
