Testing Super High Speed Steel Vanadis 60

Larrin

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. read more

Testing Chinese Knife Steel 8Cr13MoV/8Cr14MoV

Larrin

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. read more

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. read more

Does Damascus Outperform Super Steels? Testing Different Combinations

Larrin

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. read more
