The following is a collaboration project between myself and Malachi Chou-Green. He obtained the Vanadis 60, did some heat treating experiments, and also did metallography including some fancy electron microscopy. He also heat treated and machined the CATRA knife that I tested. His original experiments were published some time ago on his Patreon, so if you want to see what he is up to I recommend visiting his Patreon page and becoming a supporter.
Thank you Patreon Supporters!
Thank you to my Patreon supporters who help make these studies happen. Patreon funds were used for purchasing two ultimately useless knives, and some steel. Patreon supporter Marcus Ho even sent me some steel all the way from China which also ended up not working out. And I used Patreon funds to pay Shawn Houston (also a Patreon supporter) to do microscopy and grind two CATRA knives for me. So when I say that Patreon makes the study happen I don’t mean in an abstract sense. If you want to help fund more knife steel research please come join us on Patreon where you can get articles and videos early. Or if you sign up for the highest tier you can even get a sweet Knife Steel Nerds mug.
Thank you to all the new Knife Steel Nerds Patreon supporters! Your support allows me to do new exciting experiments on knife steel. Some exciting ones coming up in the coming months!
Video
I also have a video which covers the same information (more or less) in this article.
I drove my family all the way out to Bethlehem, PA to film a video about steel history so I hope you watch it. Read about my knife steel history book here: https://knifesteelnerds.com/2023/05/09/new-book-the-story-of-knife-steel-innovators-behind-modern-damascus-and-super-steels/

K390 Steel and Heat Treating Background
I already have a video and article about the history and properties of K390, which you can see here. K390 is a powder metallurgy non-stainless steel with high wear resistance due to very high vanadium, 9%. It is in a similar category to CPM-10V and Vanadis 8.
New YouTube video is a Q&A from Knife Steel Nerds Patreon supporters. The following topics were covered:
Nitro-V vs 14C28N
Carbide pullout during sharpening
What is difficult about high hardness heat treating of MagnaCut
Thanks to the new Knife Steel Nerds Patreon supporters! The newly performed research in this article is all paid for through Patreon funds, such as the purchase of expensive Damasteel. Patreon money is only used for knife steel research.

It’s been a while since I posted a full article, so there are a bunch of new Patreon supporters. Thanks to our new supporters Jack Hilton, David Heleander, KevinP, huck, Dd, C, Brian Fencil, Rick Steele, Leon Rodak, Kendal Thomas, The Madman, Michael Kelly, Allen Thomas, Jim Pickard, Linqian Chen, Matt Masuda, Nick Dunham, Fikes Lee, Timothy Becker, jmasinter, MakaBones, Will from Maine, and Charles. Please go to Patreon.com/KnifeSteelNerds if you want to be a supporter. Damascus is very expensive and this is one of the priciest studies I have ever done for Knife Steel Nerds. I spent several months and about $10,000 to do the following study. Without reservation, I can say this is the biggest study on the performance of pattern-welded Damascus that has ever been performed. Your support means we can do more studies on knife steel that would be unrealistically expensive otherwise.
Blade Show is almost here! The biggest knife show in the world is always a good time, and I will be there again. You should be aware of a few things at the show if you are a Knife Steel Nerd.
