I'm a scuba diver. Ever since 10 years ago I wanted a Boker TI-mariner. Its a fixed blade knife with a tang handle, available either blunt point or sharp, and semi-serrated or straight. It has two edges.
Titanium is fascinating stuff. Can't beat the weight, and I love how quick it heats up in an alcohol stove or pot. Is the edge coated with something though? From my experience, edge retention is not it's strong suite.
Scuba divers like Titanium because it doesnt rust or tarnish. The new one is heavier and not as cool. If I lost the new one in the rocks, I wouldn't be upset.
