Comparison between 440C (1.4125) and Böhler N690 (1.4528):
  • 440C stainless steel and Böhler N690 are both high-quality materials suitable for crafting various types of knives, from hunting to culinary tools. 440C, known for its high carbon content, excels in applications where superior edge retention and easy sharpening are critical, making it an ideal choice for hunting and kitchen knives. It offers a cost-effective solution for blades that are frequently sharpened and used regularly.
  • On the other hand, Böhler N690, fortified with cobalt and vanadium, provides exceptional wear and corrosion resistance. This steel is perfect for crafting dive knives or high-end culinary tools that need to withstand damp environments and rigorous use. While the two can be used interchangeably, the decision between them should factor in specific usage and maintenance considerations. N690 is your go-to for applications demanding prolonged sharpness and exceptional durability, especially under harsh conditions.
