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 saltwater corrosion, and it 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 the rope. The crystals help the edge keep it's shape and integrity over time (i.e. exceptional edge-holding) and enhance it's penetrating power, for deep cutting action.
Each sharpening exposes a fresh set of hard carbide micro-teeth.
