"David Boye's new revolutionary 'Dendritic Cobalt' is an incredible high-performance cutting alloy." -Larry Connelley
David Boye has long been one of the most respected knife makers in the country. In 1971, he published the "textbook" on knifemaking which is still in print. After learning about his new dendritic cobalt I immediately gave him a call. We are excited to be the first dealer of David Boye Knives.
According to David each Boye knife is handmade to be a "using knife" which can be easily sharpened by hand on a good Arkansas stone. Boye Dendritic Cobalt, while often called Boye dendritic steel is not actually steel, but a metallic alloy composed of over 50% cobalt, 27% chrome, and nickel, tungsten, silicon, molybdenum, iron, and carbon. Each blade is individually cast to shape in it's own porcelain model. The carbide crystal dendritic formations provide "micro-serrations" on the edge which aid in cutting (bite) and help maintain the structural geometry of the cutting edge. What Boye calls the "dendritic cutting effect" is similar to the "Damascus cutting effect," where hard and soft boundaries form a serration effect along the microscopic edge. In dendritic steel, the hard formations are chrome carbides of very high Rockwell. These form a fern-like network throughout the Rc 56-58 steel matrix. Each blade is impervious to salt water corrosion and is non-magnetic. This makes them great for boating in harsh freshwater and saltwater environments.
The "lost wax" process for making a Boye knife blade is a centuries-old technique for making all kinds of intricate pieces. In the casting foundry, hot wax is shot into the aluminum mold, and when it cools it is removed as a wax model of the knife. With the wax burned out, the hot mold is ready for the molten steel, which must be poured while the mold is still red hot. As the poured steel cools, the carbide crystal network forms throughout the blade. The model is broken away, and the individual blades are trimmed, annealed, and sharpened. It is an exacting process and many castings are rejected. Boye states this method of producing blades, "is more expensive, pound-for-pound, but I feel it is well worth it in the long run."
