Since it sounds as though you are carrying a good hatchet or axe, and are rather regularly around saltwater. My reccomendation goes to the F1. Great little knife that does most tasks really well and which will hold up exceptionaly well around saltwater.
The Bravo 1 stainless would also be a good choice but the handle does not have as much traction when wet as the F1.
