  1. Thanks for what you are doing. There is so much misinformation, hyperbole, and exaggeration being presented as fact on the internet regarding knife blade steel. I felt like the skies cleared when I discovered your site. I really appreciate your science-based approach to demystify so many issues.

Vanadis 8 – Better than CPM-10V

Thanks to Will and Justin Mann for becoming Knife Steel Nerds Patreon supporters!

My book Knife Engineering is available for Christmas and Hanukkah presents.

History of Vanadis 8

The history of Vanadis 8 goes back a lot further than just the steel itself, really we have to know the history of 10V to know all of the background that is relevant. You can read about CPM-10V in this article. CPM-10V is important because Vanadis 8 is intended as a replacement for CPM-10V, or at least for similar applications. CPM-10V was developed by Crucible in the late 70s, as the first powder metallurgy steel to utilize a microstructure made up of only vanadium carbide, as opposed to chromium and molybdenum/tungsten carbides. This gave 10V a combination of good toughness along with very high wear resistance from the ~10% vanadium and therefore ~17% vanadium carbide. read more

I’m eventually going to stop plugging my book Knife Engineering in every new article, but that day is not today. Go buy one for yourself, and everyone you know, as a Christmas present. read more

What is the Future of Stainless Knife Steel Design?

Thanks to Aram Compeau, Gordon Olafson, and John Walton for becoming Knife Steel Nerds Patreon supporters! I have an update on Patreon about the “rare earth” elements in AR-RPM9 steel.

I completed a minor revision to my new book Knife Engineering to correct a few typos. Some readers outside the USA also asked for more conversions from Fahrenheit than were present originally, so I incorporated both Celsius and Fahrenheit everywhere in the book in the text and tables, though some images and charts still have only one temperature scale or the other.  I wouldn’t say that the changes in the revision are big enough to buy a new one if you have it already, this is not a new edition, but if you haven’t purchased one yet this is as good a time as any. read more

CPM 10V Steel – History, Properties, and How to Heat Treat

Larrin

My new book, Knife Engineering: Steel, Heat Treating, and Geometry was released last week. The reviews have been coming in and the feedback is very positive so far. Go get one! And make sure you leave a review on Amazon. Also, Australian readers are now telling me it is possible to buy the book now from Amazon USA. So if you had issues ordering in the past give it another try. But do not order from Amazon Australia, see my article to learn why. read more
