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.

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.

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!
Why is there a huge discrepancy with 14c28n toughness results. Older charts Say it’s a 3. I’ve abused my Kershaw blur since 2013 and never had issues. You have it at a 9 I think. Which is fantastic
Is DC53 tougher than 14c28N? Google ai says that it is. But it explains that DC53 is twice as tough as D2. Which D2 is not that tough. As far as I understand, 1.4116 is tougher, and I found a chart that says it’s rated as a 2.5 out of ten. When 14C28N is a 9 out of ten.
I have not tested DC53 but it would be unlikely to be tougher than 14C28N. I wouldn’t bother asking any AI these types of questions. My tests for A2 were around 15 ft-lbs. A2 has the same carbon but 3% lower chromium, which would likely give it an advantage in toughness over DC53.
