Larrin's Got a Book

Larrin, congratulations. This book is the best knifemaking metallurgy book I have ever read. Well written and very clear and concise.

I scanned through the book last night. I'll likely read it page for page in the next few days. Excellent book. Plenty of technical stuff well explained for those who want that type of info, and straight non-nerd info for those who want it in simple terms. I think the HT info in the back will become the standard reference for most knifemakers.

I was very impressed how Larrin put the technical info is regular wording. While he and some others may understand things like "The t3 transition of the alpha carbides are submissive to the delta prime cementite at concentrations above the eutectoid ....."(pure nonsense example).
Most folks will understand the words he uses in thing like , " ... austenitizing times are set to be long enough to reach the point where ....".

I was very interested in the S35VN info. I am going to change my HT austenitization to 2000°F.

I did the same with s35vn.
 
Thank you Larrin Larrin , I really enjoy the book!

Your book is definitely worth every Swedish crown I paid for it (which in reality actually was euros though). You've found the perfect level of detail, not too general - but also not too technical. It's just a phenomenol book of facts. The scope is just perfect for my needs, everything from the fundamentals down to individual ratings of steel. I love it!

Naturally, I've read a lot of the content at Knife Steel Nerds, but having it all in one physical place is even better. There's something about physical books...

It's simply a one-stop shop for fact-based knife making knowledge. It even has numerous heat treat recipes at the end, goddammit!

Beginners to the knife making game will definitely get a quick-start with this in their hands.

Revived my copy today. Wow this is going to be great source of knowledge for us knife makers. After thumbing through I went straight to the back to HT recommendations. Had a couple of surprises. Recommend quenching oil for 52100 and 80crv2 is fast oil. My understanding is to use medium speed AAA oil. So I am confused as always lol

Both are low alloy steels with low manganese so they require faster quench rates because they are somewhat shallow hardening.

You can read all about it in the quenching chapter.

Datasheet for 52100 recommends water when using lower aust temps, so fast oil makes sense.
