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.

This article has a moderate amount of background metallurgy information in it. I explain briefly the necessary background information and provide links to earlier articles with more complete explanations. However, to get a full picture of steel metallurgy and heat treating, the easiest way is to read my book Knife Engineering.

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.
Thanks to Gabe Newell, George Thorpe, Jason, Rogelio Escobedo, Wes Newman, and Wayne Sears for becoming Knife Steel Nerds Patreon supporters! On Patreon there is a new article exclusive to supporters about Artisan Cutlery’s exclusive steel AR-RPM9. The composition was recently announced so I analyzed the composition.

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.
Update 4/14/2024: Gameco is sold out but Amazon Australia has it now.
