Any experiences on that folks here could share?
Or has anyone perhaps even done somewhat "controlled tests"?

Re: Ok, could it be that LC200N fares better against Magnacut than some might think?

Thanks, Larrin! Makes me wonder a bit what Eric meant in the shot show vids by saying something along the lines that edge retention and wear resistance (he used both terms) of LC and MC could be really close, and it would be not "totally obvious" that MC holds an edge longer... (https://f...

Re: Ok, could it be that LC200N fares better against Magnacut than some might think?

LC200N has higher toughness and corrosion resistance than MagnaCut. MagnaCut is capable of higher hardness (64 vs 60 or so) and MagnaCut has much higher wear resistance.

Shot Show 24 with Michael Janich - did NOT watch the vid yet (no time), but appearantly it is mainly about the "Salt" steels, could be interesting for this thread

I just came here to ask what wireless usb microscope did he pick up off of Amazon? His images look a bit better than the ones my $30 version produces.

Re: Science of sharp 15v analysis

I always like seeing Todd's blog articles; his imaging is always top notch. I had a lot of thoughts about his study. Some of my thoughts and questions are critical of the study. Since Todd is a fellow man of science I figure I can write about those things publicly without hurting his feelings. It me...

Re: Böhler K888 Matrix Steel

Wouldn't k890 still be far tougher that any average user would actually need/even notice, while having better edge retention? Knowing Bohler, though, I'm assuming k888 is gonna be to k890 what Vanadis 8 was to Vanadis 10. Either way, New steel is always interesting! How much toughness is necessary ...

Re: Böhler K888 Matrix Steel

Bohler has never done my toughness test before and I doubt they would start now so I wouldn’t go putting those values on my charts.

My analysis is on Patreon since I didn’t want to do a bunch of property predictions in an “official” video/article.

Re: New Discoveries found in 8Cr13MoV testing

Shawn ground the CATRA blades and did the “metallography” for this study so he helped a lot with the study. Metallography includes mounting the steel in epoxy, polishing, etching with acid, and imaging on the microscope.

Hi Larrin,

I just received a Manix Lite weight in Magnacut. Nice piece. My wife, Gail, carries her serrated Native in Magnacut quite a bit. We're on island and it works well.

I usually don't document anything more than just memory and maybe a few notes in my sharpening journal, but this thread has convinced me to change that.

Happy Birthday Dr. Larrin S. Thomas,Ph.D. 🎉 I think I did that correctly 🤔 You sir are a Legend 👏👏👏
That’s right, Dr. at the beginning, Ph.D at the end. And Ph.D needs the period for the extra classy touch just like Cindy Crawford’s mole.
