Many would argue this is the ultimate in 'mainstream' knife steels and you would struggle to find any steel with better edge retention, toughness and stain resistance for the money. In 2019, a decade later, Crucible introduced CPM-S45VN which essentially incorporates an extra dollop of chromium...
The carbide structure of knife steels is controlled by the composition and the production method of the steel. The microstructure has a strong effect on the final properties of the steel, though there are exceptions where the carbide type and size does not lead to the toughness that we might ...

An evolution of CPM S35VN (itself an advance over the original RSK® Mk3's CPM S30V), this steel offers an outstanding balance of edge retention, wear resistance, corrosion resistance and toughness (Click for more about CPM S45VN at Knife Steel Nerds). The blade is given a stonewashed ...

Naming the Steel – CPM MagnaCut I wanted a name that made it clear that it is a knife steel and also calls back to the history of steel. One of my favorite parts of Knife Steel Nerds has been researching the history of steel development and which companies and people contributed to the...

Thanks to A.N. Nash, Matt Collingwood, Noah Cowan, James Pierce, and Jay Caponetti for becomingKnife Steel Nerds Patreonsupporters! I have a new CATRA edge retention testing machine. I will be posting results as they come in to Patreon and articles summarizing the tests will come later to...
No new Patreon supporters this week! I think this is the first article where I didn’t have any new people to thank at the top. Thanks to all my currentKnife Steel Nerds Patreonsupporters. Corrosion Resistance of Steel At its most basic, chromium in steel leads to the formation of a chr...
