204 CBN - a set of two CBN sharpening bars (Cubic Boron Nitride) from Spyderco Company. The rods were made of a material called borazon, a polymorphic variety of boron nitride. It is an extremely hard synthetic super abrasive material rated at 90-95% of diamond hardness, however, with greater chemical and thermal resistance, so it can be used to process alloys and iron-based steels in which you can not use a diamond. Due to its unique properties, its price is on average 30% higher than the price of a diamond.
The rods match the iconic Spyderco Tri-Angle sharpener (204MF), the best sharpening set available on the market!
Rods with a triangular cross section of 7"x 0.5" (178mm x 13mm) with a weight of 49.5 g each. The regular grains of boron nitride covered by the embankment with bonded ceramic materials collect steel to a much greater extent than diamond rods. The sharpener has 3 working edges, including one with a groove for sharpening fishing hooks, pliers, small tools.
