Last night, I had a great opportunity to attend a presentation by Shawn Houston, aka Big Brown Bear aka DeadboxHero DeadboxHero arranged by the American Society of Metals, and sponsored by Niagara Specialty Metals nsm nsm

The title of the talk was “The Real World Differences Between Particle Metallurgy Steels and Conventional Ingot Steels for Knives at the Edges"

Shawn is an eloquent and dynamic speaker, who commenced his presentation by outlining the importance of regimented and structured testing, utilizing a variety of standards including but not limited to BESS testing, mircoscopy, goniometer testing, and hardness testing. The scientific acumen and hygiene he displayed was thorough, and remarkable.

I especially appreciated some of the microscope imagery, and his metallography. It was his metallography that finally got me to reach out to him, as not only were some of them exceptional demonstrations of the microstructure of the representative materials, they were beautiful in an artistic sense. It’s a rare thing to have something that is not only technically illustrative but also aesthetically appealing. I would gladly hang an enlargement of his metallograph of Magnamax in my living room.

Of course, I’m a sucker for fine, hard carbides with nearly perfect distribution, so maybe it’s only beautiful to me.





Perhaps, for me, the microscope images of the edges of his test blades after the testing was the most telling. Truly obvious disparity from ‘real world’ use:

The evening closed with a brief Q&A, where Shawn continued to show the depth and breadth of his knowledge by answering some tricky questions on the fly, managing to keep the answers pertinent while cutting through to the meat of the topic. Tim Gelnett, Vice President of Niagara Specialty Metals, presented him with a plaque in appreciation of his efforts.

On a personal note, I got to meet Shawn in person for the first time, and found him gregarious and approachable. Definitely a driven young man with a great sense of humor, and aptly nicknamed. I also had the chance to catch up with some of the old guard from Niagara, had a good chat with former Crucible metallurgist and now Erasteel metallurgist Bob Skibitski, as well as a couple of the Erasteel reps. Overall an enjoyable and informative evening.

If the opportunity presents itself, I would strongly suggest attending any demonstration or presentation that Shawn offers.
 
Hope this isn't a dumb question but is this presentation/slide show available anywhere?

I was just pondering the real world value in some of these ingot vs PM steels like CPM D2/154 and D2/154CM. As in is it a big enough difference the average user can tell or not. Not asking here, that was just what was in my head to look into later.

And then poof, this pops up...!
 
This is really cool. Would like to see the presentation slides. I love real-world testing and I think hunting knives are great examples. Virtuovice would test different steels and would count the number of deer he could dress before needing to resharpen the knife. Some steels were good for 3 to 4 deer while others could only do 1 or 2 before dulling. Some were more chippy than others. His videos are old (15 - 20 years ago) but are still on YouTube and still very good IMO.
 
Any link to watch the presentation?

It would be Shawn’s choice to produce something like this presentation for consumption beyond the event. I certainly didn’t record it, beyond the photos you see here.
 
Not trying to be contrary at all. But 440C is an old school steel and Magnamax is the newest thing. It kinda like comparing a 2004 Hyundai to a new Camry. The OP only presented a small piece of the presentation so I figured maybe some other comparisons were made.
 
It's a matter of degree and what one is willing to pay. SV35 is great, but how much is it worth to jump to the next level?

Just food for thought, but if you brilliant makers/metallurgists put out videos for a fee or subscription I would gladly pay to learn more. I may not understand some of it that is over my head, but I always enjoy learning more.,

BTW, I find it awesome how so many of you experts support each other.
 
What was the overall finding? The slide comparing 440C to Magnamax is telling but not surprising. Comparing something like CPM154 to CM154 would be interesting. Did that come up?


Well, I’m not one to ruin things with spoilers, but at the end it turns out that not only is Luke’s father Darth Vader, but Princess Leah is his sister.

I’ll leave it to Shawn to share the findings, should he elect to or not. 😉
