Honestly I wish I had more friends that talked about carbides

I shit my pants when Mr. Owl said, "I DON'T KNOW, IM A PUPPET!!!" 😂😂😂😂😂😂😂😂😂

This is amazing. Thank you.

I'm 40. If I learned everything like this, I would have made so many better life decisions

As a huge nerd who also happened to grow up in Pittsburgh watching Mr. Rogers (I ran into him on the street as a child!), and who has a strong affinity for low-budget/high-earnest nonsense, this absolutely made my day. From the bottom of my heart, thank you!

Everything from 7 min onwords is just... stunning. A YEAR of bladesmithing education in 12 minutes. I paused a dozen times to digest your amazing presentation, which is of course an option we are supposed to take. I am new to the blademaking world, but I have been an armchair enthusiast for ten years and more. This video was a revelation in how much I still have to learn. Magnificent.

Definitely have to give the vid a like for Jessica having to suffer through a speech on carbides and potentially, having to also listen to talks about carbides about the home

Your blog has been an invaluable resource to the community, however this is art, absolutely hilarious great work.

Hi. I'm a Pittsburgh guy who just found your channel. My dad worked at the US steel lab in Monroeville and I'm a former steel worker myself who of course grew up on Mr Rogers and became a knife collector, a logical progression. I'm going to enjoy catching up on all of your videos I plan to spend the evening binging on knife steel nerds

A must watch for every knife enthusiast, the complex subject of edge retention by steel properties nicely explained in simple English. Larrin at his best, a breath of fresh air, listen to every word... As much as educational, it is entertaining. Thanks to men like Larrin life is good.

Best video ever! Like ever. Thank you for pointing out the extreme toughness of lc200n, all the knife stores have its toughness lower than s30v 🤦‍♂️

Data-backed information is incredibly valuable, in light of the poor information and opinions posted in forums, etc. Really appreciate the time and effort put into producing this video. To everyone else wishing they had someone to talk steel and carbides with, cheers!

This is one of those videos that the people in the knife community should watch, no matter your experience

Mr. Owl was the unsung hero of today's lesson.. also whoever was playing the piano.. bravo!

You are the BEST! That was great. Good production AND educational. Shout out to Miss Jessica. Thanks Larrin. We appreciate everything you do. Keep up the work.

Bravo Knife Steel Nerds! Thank you for instructing us on this subject exploration is straight forward and lucid. So much to learn about metallurgy.

I have been promoting your blog for years and years, tirelessly. As a fellow principle investigator, it was absolutely a breath of fresh air to read a well cited, and scientific aproach to knife steel attributes. I went to your site initially for fact-based steel recommendations, and I came away with a deeper appreciation for metallurgy. You have done an amazing job promoting interest in your research, the field you work in, and science.

This is an amazing video! a wealth of knowledge in a simplified format! Please make more of these !

Quality content! Amazing and thank your Mrs for allowing herself to be featured! I hope both of you do this again!

Huge eye-opener, it can so hard to get a sense of how different knife steels actually compare. This video is for sure going to become a point of reference for all knife steel debates for the foreseeable future, you've done the whole community a favor here. Thank you.

Oh my gosh. I have found my new favourite niche on the internet!!!! Love this, guys! Already a follower of Knife Steel Nerds through content on your site but only just found this on youtube. So awesome and perfectly hits my steel nerdiness and humour!

Great video! I am very happy to see new upload. I hope there will be much more.

Fantastic video. Love the cheeky Mr Rogers fun. I have been looking for a video like this that breaks down the different metals. Thanks for putting this together for us laymen. Really appreciate it.

Dude, you're my new favorite knife channel. Humor, mixed with knowledge, visuals and tests!

This video makes me so happy. Thank you so much for all the work you put into the Mr Rogers omage

Your knife engineering book is incredibly interesting and it is fantastic to have an extremely accurate, impartial, and well written text book that only concentrates on every aspect of steel, and not on brands of knives. It's a wonderful book and you have provided a superb edification on steel. Thank you Larrin :).

FINALLY! Best and most thorough charts and explanations thus far in my, close to, fifty years of owning and using knives. THANK YOU.

Best steel-explanation ever! I am saving this video to share to a friend every time they need a short crash course on steels types.

That was amazing. Such a nice homage. Love the piano. That picture picture gag had me laughing hard. So informative. Thank you so much.

Great video. Great learning resource. I live outside of Pittsburgh and used to work there. Mr. Rogers was a local favorite TV show when I was a kid.

That was an awesome video. It's very informative and great humor. Keep up the good work Larrin!!

Outstanding presentation of very complex information. Thank you for being here.

This is EXTRA funny because you're ACTUALLY my neighbor. 😂

Outstanding, I'm happy to support your work on Patreon.

This was absolutely brilliant! Great job on both the information and the entertainment value!

This is excellent, I hope for more content from you. I will for sure be telling people about your channel.

This is amazing. Thank you for taking the time to explain this all so clearly.

This is rapidly becoming one of my favorite channels on KZfaq. Powder metallurgy info AND knives. My professional and hobby interests colliding.

Thanks for the great content! I would love to get even more knowledge about the different knife steels and their properties!👍🏽

We love you, Dr. Larrin!!! Thanks for the great info & R&D! 😃

Excellent information. Thank you for breaking that down in a way I can share with new people.

Absolutely priceless . Thank you so much fire what you do for the knife community . I hope you keep this up

Third video of yours I've seen today, will be ordering the book. Excellent information.

Thanks Fred! I'm 82 and it's never too late to learn about blade steels! My kids used to watch your show when they were, kids!

Awesome! .... You covered the steel blind spot for knife makers!!! I'm glad I bought your steel back in April

This is the best video on the Internet. I have had every steel question I've ever had. Great work! Also: don't ever make her do some crazy one-take monologue! That was quite an assignment well executed.

i had fun and I learned some new things. Thanks for your effort Larrin!

Very well laid out. I'd like to see your version of this including various heat treating methods for some of the more popular steels and the final hardness and tempers effect on edge retention, wear resistance and toughness

Thank you so very much for your work!❤️ This is one of the most meaningful contributions to the knife discourse ever in history!

This was amazing !!! Not only did I learn something I laughed . Great job I love your book and videos such a major help for knife makers!!!!

Dam that was both nostalgic and extremely fun and educational at the same time. Thank you .

This is SOOO very helpful for someone in his infancy of collecting and learning about pocket knives and steels. Thank you so much!

How the hell have I only stumbled across you now?! This channel is amazing. All the info you search around and get marketing guff or subjective nonsense. Wow, thanks for this content. Love it.

So much love for this video, excellent neighborly insight!

I love this video🙂 watched it several times. Learn something new each time. Thank you Dr. Thomas!

New subscriber, awesomeness Larrin looking forward to binge watching this holiday season. Blessings and Aloha from the Great Lakes USA (Michigan)

Awesome content from an invaluable member of the knife community. I hope there's more where that came from.

Very entertaining and highly informative at the same time. Wonderful job!

Holy cow that’s an amazing video. Outstanding effort and knowledge sir.

Brilliant!! Thanks a lot for all the effort you put into this video.

This was done with mad respect and great knowledge thank you.

Great work as always Larrin, thank you! I really hope this starts paving the way for online knife shops & 'experts' to stop spreading misinformation & actually educate folks with real facts & figures... (fingers crossed) Cheers

Thank you, all knife channels should link this in their notes

Very entertaining! Makes all this metallurgical stuff more digestible. Thanks!

Loved this, thanks for making it.

I'm a metallurgist. Had many metallurgy classes during my undergraduate. Closest course was about "Tool Steels", wish we could have had a class about knife metallurgy. I'm a life long learner and always eager to learn new metallurgy, and this topic is really informative

You mentioned that edge angle causes chipping, but so do manufactured burnt edges when they sharpen on grinders and belts without water being fed over them. Once you sharpen away the burnt edges your edge angle becomes better at resisting chips at that angle. But otherwise your correct 100% if there were no burnt edge. I say this because its very common in the industry and you yourself have written about this.

Keep it coming man. Nice work!

Great explanation. Feel like I learned so much in such a short video.

This is one of the best things I have ever seen on the internet. Well done!!!

Thanks for the edutainment gentlemen, much appreciated! Sterling!

Hahaha, Thank You Mr. Neighbor for the very informative talk. It was hard to watch without smiling. Nice to see you have a good sense of humor Doctor Thomas and thanks to the wife too, very cute. I have learned a tremendous amount about steel from your articles but will watch anymore vids you put out. It did fill a couple gaps.

I've been reading and referrencing Z Knives' knife steel database for several years and your presentation put everything into context. Thank you.

So much fun and so much good info. Thanks for this!

Very well done! Would love to see more of these =]

Awesome man I could watch an episode like this everyday

Just discovered your channel. Love your work.

Very nicely done! Great video production also!!!

this is the perfect mix of oddity and Pertinent information. Well done.

great rundown and I dig the Mr Rogers reference. I grew up with him, as you likely did. You also do his cadence justice.

Thank you for the work you do sir.

Very good video mate Magnacut has for sure impressed me the combined attributes. Its tough for outdoor use and has good edge retention and is very very stainless also.

I don't have anything to say that hasn't already been said. The information I got from the video is invaluable and I truly hope you guys continue to pursue the ever developing science of steel! Truly incredible!

Excellent! Fascinating video, well done!

Excellent video and information thank you for sharing 👊

Never will I understand those few who put dislike for such a clever, clear, talented video. Putting dislike for this video is a clinical diagnosis of a deficiency, mental or spiritual or worse.

Love it! I worked next to an arc furnace filling carbon into the bins. Spent hours watching the Lance blow coke into the furnace and it fascinated me and I have been into knives and steels since. Thanks for the hard work!

I love this video Larrin, very inventive, well done!

Great video and thank you for these useful informations. well done

Great Video.. you made something highly technical fun and "easier" to understand. It is certainly a huge Market these days as the blade dteel is what allows Mfg's to charge the prices they do for certain Steels. Id love to see more on this subject and possibly compare and contrast the top 20 blade steels in some clinical trials.. Love the Mr Rogers production as well!! great trolley budget and Jessica / Mr Owl..

Great information, engaging presentation, truly making life better for all of us non-chemical engineers looking for real understanding

I know videos are far more work for you than blog posts on the site but thank you so much for making this. The regurgitation of opinion or straight misinformation is too common. So in this day of infinite information, which can be provided by anyone and accessible by everyone, true straight forward data and information is invaluable!

Wow! What a treat! I was searching in the difference between Martensitic Steel and R2 and found an article that included this.

This is the best blade steel video ever produced. Simply excellent

You are the man Mr. Thomas. Your book is pure gold. Thank you

Absolutely brilliant video I loved all the information and so happy to know I just bought a magna cut knife from Bradford knives looking forward to trying it out

This is amazing. On so many levels. I remember Mister Rodgers so this just amizing!!!

Thank you for this informational video. Helps me a lot

Charming and extremely informative!

This was classy. Very entertaining and I learned a little also. Great job.
