David Boye has long been one of the most respected knife makers in the country. In 1971, he published the "textbook" on knifemaking. Boye knife blades are made from dendritic cobalt. Dendrictic cobalt is not steel, but a metallic alloy composed of over 50% cobalt, 27% chrome, and nickel, tungsten, silicon, molybdenum, iron, and carbon. This blade alloy is PERFECT for the boating community because it won't rust in salt water! Proudly Made in the USA.
