Shackle Key
Integrated directly into the blade, the shackle key allows for quick, practical adjustments onboard — ideal for loosening common sailing shackles and handling small rigging tasks with ease. By incorporating this nautical tool into the blade itself, the No.09 Ocean avoids unnecessary bulk, keeping the knife lightweight, compact, and easy to carry whether at sea or on shore.
Marlin Spike
Folded discreetly into the handle, the marlin spike is an essential tool for ropework and marine tasks. Designed to help loosen knots, separate strands, and handle splices more easily, it adds true nautical functionality without compromising portability. Its folding design keeps the profile compact and streamlined, making the No.09 Ocean a versatile companion built for life on the water.
