Boye Dendritic Cobalt is a super-performing, non-rusting cobalt-based alloy that excels on tough fibers such as hi-tech rigging line, deck line, and net. Not a steel, it is a mixture of cobalt, chrome, nickel, tungsten, silicon, iron, and carbon. It cuts aggressively and keeps cutting. It is completely impervious to seawater corrosion, and is non-magnetizeable. Each Boye blade is permeated by a dense, branching, “dendritic” network of hard carbide crystals. At the cutting edge, these carbide crystals produce micro-serrations, which can be felt with the fingertip and heard when the knife slices through rope. The crystals help the edge keep its shape and integrity over time (i.e., exceptional edge-holding) and enhance its penetrating power, for deep cutting action. Each sharpening exposes a fresh set of hard carbide micro-teeth.
