MagnaCut steel was invented by metallurgist Dr. Larrin Thomas, who created the material to achieve a rare balance of high toughness, wear resistance, and excellent corrosion resistance in a stainless steel, an ideal combination for knife blades. He achieved this by designing a novel microstructure that resembles that of non-stainless steels, leading to MagnaCut's exceptional performance in 2021.
Key details about MagnaCut's invention:
The Inventor:
Dr. Larrin Thomas, a renowned metallurgist known for his work on knife steels and the KnifeSteelNerds blog.
The Goal:
To create a single stainless steel with the high toughness of some non-stainless steels, combined with excellent wear resistance and corrosion resistance, properties that are typically difficult to combine.
The Method:
Thomas developed the concept for MagnaCut's microstructure and then worked with the steel company Crucible to produce it as a powder metallurgy steel.
The Result:
CPM MagnaCut was introduced in 2021 and has gained popularity among knife makers and enthusiasts for its superior performance and durability.
