Podcasts
I appeared on two podcasts this past week, Knife Perspective and Mark of the Maker. Knife Perspective I had been on before so we mostly focused on MagnaCut and other topics. Mark of the Maker was a full interview asking about my background before discussing my book, website, and CPM MagnaCut. So listen to one or the other or both depending on what you’re in the mood for.

What Causes Razor Blades To Dull
Thanks to Mike Strickland, Joe Dickens, Carson Reid Davis, Kenneth, Jordan Danz, Wade Smith, Jeremy Kline, and Ryan Guldbrandsen for becoming Knife Steel Nerds Patreon supporters! I have posted initial results of experiments testing my new powder metallurgy knife steel. So come join Patreon if you want to see how the steel is doing before everyone else.
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.

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.
M398 Steel Testing – Edge Retention, Toughness, and More
Thanks to Joel Sunderland for becoming a Knife Steel Nerds Patreon supporter! And thanks to pog for increasing their support.
The steel ratings table from my new book Knife Engineering has now been added as a Patreon-exclusive with M398 added to the table.

M390 vs 20CV vs 204P – 3rd Generation Powder Metallurgy Technology?
Thanks to Josh Warren and Alex K for becoming Knife Steel Nerds Patreon supporters!
Edge retention testing is continuing, we have now tested 18 different steels, and four of those steels with multiple heat treatments. Come to Patreon if you want updates on testing as it is completed.
How to Heat Treat CPM-154 – Toughness Experiments
Thanks to Mikolai Kawai and Tyyreaun for becoming Knife Steel Nerds Patreon supporters!
I have now published two CATRA edge retention testing updates to Patreon for those that want a preview of testing before a full article will eventually be written.

Just out of curiosity, did you ever test ztuff with a high temper. At one time I did some testing, and found it to be much tougher if tempered at around 1000 degrees. This was compared to tempering at 400 degrees!
I haven’t tested the high temper on Z-Tuff.
I think it would score quite a bit higher on you’re charts! Maybe in the future I could heat treat a few samples and send them to you. I’m interested personally!
