    3 new steels designed by Larrin

    We are very premature for announcing anything apart from MagnaCut at this point since neither of the other two mentioned steels have been produced in full quantities. But laboratory development is very fun.

    Which Quenching Oil is Best for Knives?

    The W2 came from NJSB. The suppliers/manufacturers are listed in the written article. Agitation helps break up the vapor jacket and would therefore be expected to potentially increase hardness.

    Which Quenching Oil is Best for Knives?

    The papers I looked at on canola oil and other oils did reference specific heat capacity measurements so that does seem to be an important measurement.

    Which Quenching Oil is Best for Knives?

    When I google specific capacity all I'm finding is a term referring to well pumps. Do you mean heat capacity?

    Which Quenching Oil is Best for Knives?

    I did a big study on different quenching oils (six of them) in addition to water for 9 different steels to see in what conditions the different steels will fully harden. If you have been worried you are using the wrong oil this study is for you. In addition to this fun study, I have made my...

    RIP Cliff Stamp

    Very shocking for sure. I'm happy he was able to help edit my book. He always had something interesting to say, even when he made me mad.

    Bainite heat treatments of 52100, O1, and 1095

    I am not sure if he has described the process anywhere.

    Bainite heat treatments of 52100, O1, and 1095

    Howard Clark uses martensite for the edge and around 50 Rc bainite spine so that it has more strength than the typical soft pearlite spine.

    Bainite heat treatments of 52100, O1, and 1095

    New article summarizing some experiments I did on “austempering” for bainite of 52100, O1, and 1095. There were some interesting results about how bainite gest improved toughness of typical tempered martensite. I also compared between the high carbon steel heat treated for bainite vs high...

    More Edge Retention Testing - Rex 45, Maxamet, SPY27, XHP, CPM-T15, 420, Rex 76

    A new set of edge retention tests on a range of high speed and stainless steels including Rex 45, Rex 76, CPM-T15, SPY27, XHP, and 420. We also did toughness tests on several of those steels that we had not yet been tested. And we redid our Rex 121 knife with a new heat treatment that was much...

    How to Heat Treat 8670

    A new article where we looked at a bunch of heat treating variables for 8670 to narrow down the best approach for heat treating it. We looked at austenitizing temperature, tempering temperature, Parks 50 vs AAA, and more. How to Heat Treat 8670 - Knife Steel Nerds

    How Even is an EvenHeat? How to Operate Furnaces Effectively

    Can't make everyone happy. ;) I don't know the physics of heating well enough to answer that question without giving you false information.
