Knife Steel Nerds at Blade Show 2024
I will be at Blade Show Atlanta again this year. The big thing on my schedule is a Blade University class on June 7th, Friday morning. I have done different Blade University classes the past few years and it has been fun each time. This is a general class on thermal cycling using a lot of past studies that we have done which have been published to the website and in recent years to YouTube. However, we did a new study on AEB-L and MagnaCut to have better data on how to “thermal cycle” stainless and high alloy steels and we had some very interesting and exciting results. I am hoping that we can get some more bladesmiths to start forging stainless steels instead of the nearly-universal choice of carbon and low alloy steel.

AR-RPM9 Knife Steel is False Advertising
It gets expensive to buy knives just to cut them up, and metallography costs even more. Support more knife steel research by going to Patreon.com/KnifeSteelNerds You get to read articles and watch videos before anyone else, participate in the Patreon community, and even get a free mug if you sign up for the highest support level.
Wootz – The True Damascus Steel?
Thanks to Spencer Sandison for providing the Wootz steel for this new study! Thanks to Shawn Houston for performing the microscopy. And thanks to the Knife Steel Nerds Patreon supporters who allow me to do these studies through providing funds for all the experiments. All Patreon dollars go towards knife steel experiments.
Matrix Steels K888 and CPM-1V
Thanks to Roman Kasé for donating the K888 and Niagara Specialty Metals for donating the CPM-1V. Thanks to my Patreon supporters for funding this study, those dollars went toward metallography and CATRA blade grinding. You can support knife steel research by visiting Patreon.com/KnifeSteelNerds
Testing Super High Speed Steel Vanadis 60
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.
Testing Chinese Knife Steel 8Cr13MoV/8Cr14MoV
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.
USA vs Europe – Powder Metallurgy Knife Steels
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!

I also have a video which covers the same information (more or less) in this article.
Innovators that Changed Knife Steel
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.
