Safety Essential
For the line you are wrapped in and the fish you have to dispatch. Small, sharp, and where your hand goes without looking.

It is not a weapon and not a pry bar. A small blade that is always where your hand expects it is worth more than a big one in a sheath you have to find.
Ghost nets and lost fishing line are on every Moroccan rock. A diver wrapped in monofilament at 12 m with no knife has a problem that a knife solves in a second.
What matters:
A small, cheap, sharp knife on the belt beats a dive-shop dagger on the calf.
Blade of 8 to 12 cm; handle that fills a gloved hand; sheath positioned where you can reach it with either hand, since the other may be holding a gun or a fish.
Rinse, dry, and oil the blade. Sharpen it when it no longer slices a piece of line cleanly. A knife that has rusted at the tang is retired; a rusted blade snaps under load.
