CPM-20CV Blade Introduction

CPM-20CV is a premier powder-metallurgy stainless steel, widely celebrated for its outstanding wear resistance and exceptional edge retention due to a high volume of vanadium carbides. It maintains a superb balance of hardness and toughness, making it ideal for high-performance cutlery. However, its sophisticated composition presents challenges: the extreme hardness that ensures longevity also makes field sharpening difficult for the average user. Additionally, while highly resistant to corrosion, it requires diligent maintenance compared to less complex alloys to prevent potential surface oxidation in harsh environments.
