What is Cold Steel SK-5 High Carbon Steel Blade Construction?
Cold Steel SK-5 High Carbon Steel is the Japanese equivalent of American 1080 steel, a high carbon steel with carbon between 0.75%-0.85% and 0.60%-0.90% manganese. As quenched , Cold Steel SK-5 High Carbon Steel has a Rockwell hardness near Rc 65 and produces a mixture of carbon rich martensite with some small un-dissolved carbides. The excess carbide increases abrasion resistance and allows the steel to achieve an ideal balance of very good blade toughness with superior edge holding ability. Due to these characteristics , this grade of steel has been used traditionally for making a variety of hand tools, including chisels and woodcutting saws, and has stood the test of time and use over many years in many countries. Cold Steel's working temper for their Cold Steel SK-5 High Carbon Steel knives are RC 57-58.
