A Sailing Blade

t sea, sailors work for hours or days or months within the limits of their toerails. They duck through a web of standing and running rigging, constantly balancing, minding their footing, and keeping a sailor’s covenant: One hand for the boat, one for yourself. The ancient threat of the sea is always in mind: that beyond the rails, things get wet and chancy. Sailors are not pedestrians. They don’t need car keys or change for the parking meter. What they carry is necessary, one or two basic tools. One crucial tool is a knife. It’s not optional, and it isn’t occasional. An experienced sailor has his knife within quick reach all of his waking hours afloat. A knife is a personal tool. But the demands on a sailing knife are so specific that no sailor can afford to buy a knife haphazardly, simply because it looks cool. The criteria for a sailing knife are subtle and occasionally unexpected. Before you choose, review a few of them in a pragmatic, nuts-and-bolts light. C. W. Ashley’s Book of Knots often cites line’s wicked propensity for mischief—its “malevolent intelligence.” Idle, seemingly benign line will throw a timber hitch around your foot, snag anything sticking innocently out of your clothing, or lasso your neck with a lazy loop. It’s a seagoing corollary of Murphy’s Law: Any critical limb, tool, item, or arrangement will be snared by a line; the snare will seize its object at the worst, most life-threatening, or most expensive time. Why a Knife? Even in a mild breeze, the smallest sail generates mortally dangerous forces. In a stiff breeze or in the heat of a race, the potential for disaster rises alarmingly. Lines suddenly whip out or snap taut, bronze or stainless fittings burst under strain. If a line has snared you or a shipmate, there’s only a moment to save the situation. Your first thought should be to relieve the pressure. Cut the line. Line’s valuable, for certain, but you can make it back to the dock with a jury rig or with one sail, or even motoring. You can’t replace a life. Cut the line. Be ready. Yes, the big dramatic use for a sailing knife is to save lives and limbs. Let’s hope, however, that most of your sailing isn’t especially dramatic. Life on a boat is fairly basic, and the knife is a basic tool. Day by day, dozens of things need a cutting edge: whipping line, cutting line to length, trimming splices, cutting seizings, nipping off a hank of small stuff, and opening the damn bombproof plastic packaging of new AA batteries. A sailing knife is expected to have the heft and stiffness, the basic strength, to be a widely adaptable tool. You’ll use it for prying stuck storage drawers and opening force-fit lids of various marine gunks. You’ll use it as a lever, and even as a small hammer to recall small parts to their duty. Cutting line is not like cutting
