High-grade stainless steel manufactured using the ‘powder metallurgy’ process in the USA

CPM MagnaCut is a stainless steel manufactured by the American company Crucible Industries, which is renowned for its expertise in the field of special steels. This highly specialised steel was developed primarily to meet the needs of the most demanding cutlers.

CPM MagnaCut is produced using powder metallurgy, which guarantees a fineness and purity unrivalled by ‘more common’ steels. Its composition was developed by Larrin Thomas, a Doctor of Metallurgy, well known to English-speaking knife makers. Larrin Thomas wanted to develop a steel that would meet all the requirements of knife makers. CPM MagnaCut will meet the expectations of even the most demanding users.

The balance between toughness and edge retention is exceptional; it is extremely corrosion-resistant, despite containing only around 10% chromium. The steel has a very fine grain structure and high purity.

Thanks to its many technical properties, CPM MagnaCut is suitable for all types of knife blades, whether for hunting, outdoor use or folding knives. It will be of particular interest for knives where the cutting edge must be fine and stable, such as Japanese kitchen knives. It is particularly well-suited to coastal, very humid environments, where its corrosion resistance really comes into its own.

Thanks to its fine grain structure, it is very easy to sharpen to a very sharp edge. We harden and temper the steel to an optimum hardness of around 62.5 HRC.
