Thank you for the additional information Jeff. Your point about keeping a sharp knife in reach is well taken. Whether on a commercial fishing boat, whitewater, or sailboat, a knife that you can immediately put your hand on is an essential safety item. Lobstering, we would always wear an ankle sheath. In whitewater we wear quick release, double wavy-edged knives on our vests. (I use the same vest/knife sailing.) I often see sailors wearing those belt-pouched folding do-it-all knives which take WAY too long to get out of the case and unfold. They are nice for other stuff but would likely fold over inadvertently in an emergency and cut your hand. A knife seems to be a small item to fret about but the right kind can save your life.
