Testing Chinese Knife Steel - Actually Good? (8Cr13MoV)

I wonder how many Chinese knives sold here as S35VN, AUS10 and 14Cr28 are actually 420/440. And who knows what they slide in under “D2” designation 😂

[@ssnerd583]

I actually have a cheap china made knife that says its 'D2' on the blade and for $19 I didnt think so, but....when I tried to sharpen it, D2 content found!!! That particular knife is one of the hardest/most work to get an edge back on but it lasts very well and I really like the knife. I originally bought it because it was an 'homage' to a well known brand name knife that I wanted to buy but I had no experience with that blade shape/length - it was a bit longer than my usual EDC blades and I didnt want to spend $250 to buy a knife that I wouldnt like or use, so I bought the 'cheap chinese copy' to see if it was suitable for me or not. Turns out it is one of my fave non-auto knives I have....lol @@CuttingBoardRx

Happy to see you finally test this often maligned steel! Thanks for your work. In my experience, 8Cr may not hold the best edge, but remains serviceable and touches up easily. It's also fairly tough. This is exactly why so many rave about 14C28N nowadays. I would love to see 9Cr18 done next!

[@rodgerklindt3165]

I spent my working career with Byrd knives. Used them everday, sometimes very hard. Also sharpened them quite often. For the price point I found the steel to be more than adequate.

[@chemistryofquestionablequa6252]

I carry a hawksbill Byrd folder (can’t remember the model name) it’s BY FAR the best knife I’ve had for the money and is better than a bunch of way more expensive knives I’ve owned. Cost me about $30 Canadian including shipping back during covid, the fit and finish is great, zero blade movement when it’s open. Holds a great edge and came shaving sharp. I’ve been carrying and using it since I bought it and the only issue I’ve had is one of the pocket clip screws came out, so I replaced it and used loktite to make sure they stay put. The blade has a little corrosion in spots but that’s my fault entirely. I’m a chemist and use it regularly around really corrosive stuff. I think the larger tarnished spot came from a very strong bleach solution and there are some tiny spots from hydrochloric acid. Sorry I went on for so long but anytime anyone asks me what knife they should buy I tell them to get a Byrd. Thank you for your work with such a great company!

[@joshuakeats8051]

Considering its price and availability, 14c28n seems to be the best option in its class in regard to all-around balance for a work-horse knife steel. Very good toughness, great corrosion resistance, and good edge retention in relation to its sharpenability. Judging by the graphs, It seems to be a better option than even its composition cousins of AEB-L and Nitro-V and similar hardness. I, for one, would love to see further testing of 14c28n, to confirm if its past testing was a fluke, or if it really is what we can expect of this stuff. Not to mention what to expect and increasing levels of hardness. Great work, Larrin!

[@KnifeSteelNerds]

If the 14C28N edge retention was identical to AEB-L it wouldn’t change things much. I already declared 14C28N as my favorite “budget steel” a few years ago but the slightly higher edge retention wasn’t really a factor. Mostly that it maintains similar properties to AEB-L while having improved corrosion resistance. knifesteelnerds.com/2020/06/15/what-is-the-best-budget-knife-steel/

​@@KnifeSteelNerds specifically for a kitchen chefs knife, what steel would you recommend. From watching and reading a lot of your material, my conclusion is that AEBL / 14c28n is pretty much the best, if you don't want to invest in diamond / cbn abrasives. Easy to sharpen, high toughness allows for shallow angles, and pretty corrosion resistant. Would love to hear if there is something I missed or if there are better options for kitchen knives specifically. Thank you :)

My 10 cents: the result Dr. Thomas got was from working with a small batch of steel in a very controlled environment. I am an eye witness of how large state-owned metallurgical companies and machine shops in communist countries operate, which leads me to doubt that steel on a $10-$40 PRC-made knife will have anything resembling consistency. I much prefer AUS8 and AUS10 heat treated in Taiwan: it’s almost as inexpensive and done under processes which can actually be trusted.

I would like to see that test as well. I test knives on my channel in the crudest and cruelest way possible and have “successfully” broken 2 CJRB knives in RPM9. The same test broke the S35VN blade on a Bear Ops knife and an old Benchmade in ingot D2 and Hogue Deka in MagnaCut. The geometry of each blade was different but all 4 were tanto or reverse tanto shapes. I mentally place the RPM9 toughness between that of D2 and AUS10. Curious to find out how much off I am.

[@auroraborealisknives4019]

Thank you Larrin for this excellent video. This is exactly why I selected AUS8 for my stainless version of the Wolverine. It’s a pretty well balanced steel and in a larger blade it helps to keep the price reasonable 👍 I’m joining your patreon

It shouldn't be pronounced like "jean." The "G" is pronounced the same as in "geek." or the word "green" but without the "R." So "Geengami" More interestingly, it roughly translates to "silver god." which is maybe a little neato? On another note, I quite like the Chinese naming scheme.

[@lostcat9lives322]

What the response was from your 8CrMoV supplier (Michael Ho), when it was discovered that the steel type was incorrect? Does this call into question the credibility of the certifier/ certification process? How common are such mistakes? I'm guessing that wouldn't make large-scale clients of such products very happy. I've never had much faith in the specs claimed by low-end Chinese manufacturers.

Your not telling me anything I didn't already know 🤣🤣🤣 but still nice to see hard evidence to present to the steel snobs. I've gotten into many arguments over knife steels through the years, and the common denominator for the snobs, is the newest and most expensive is the best steel. What idiots they truly are. All steels are in essence super steels. They are all stronger and harder than plain iron. However they all have different properties that make them ideal for certain uses. You can make a knife out of any steel, but it's durability and edge retention will depend on its intended use, and the hardening, tempering process used. Schrade uses 8Cr13MoV and 8Cr17Mov in their knives. I have no complaints about this stell.

Great video. Some of the other Chinese steels are much better in the knives where they are used.

(BTW, hardness tests I've seen on production knives in 8Cr13Mov tend to be in the 56-59 range.)

Serious quick question, what does a edge need to accidentally bump into large staples(something you see in heavy duty cardboard box) and came out the best? is it "toughness"? as I can slightly squish it with softer material and it bounced back? I run into those accidents sometime. (and asphalts too, rarely, but still it gets into contact with my knife too)

[@SniperAngle12]

My unprofessional opinion as a mech eng student and amateur bladed implement enthusiast, that would be hardness. The harder your edge the better it'll survive the relatively soft staple. But it depends on the edge geometry as well, if it's too thin, then the form factor takes precedence. Toughness is more so to deal with its ability to take impacts like batoning or chopping trees.

10:57 Just helping a brother out, when you plot data like that its better if you don't use a smoothed connecting line between the points. It generates features that (probably) don't exist. For example, on the No Cryo plot on the left, just below 2000F Austenitizing there is a local maxima, which implies something interesting is happening there. Its simply an artifact of the plotting software, though. With your level of measurement capacity it may be worth it to get into a different plotting software like Igor or (my personal favorite) kaleidagraph.

Heat treat is everything. I have several knives with 440A steel that I can't sharpen at all. But I have some Cold Steel knives that are viciously sharp, and I can't tell much of a difference between it and AUS8A. And when they begin showing signs of wear, sharpening them is a breeze. As knives soar past $100, few people want to buy knives with supersteel. I have a bunch of knives with CTS-XHP steel, but I just don't like them as much as my AUS8A knives. The XHP is a great steel, but I carry knives mostly for self defense and home chores. Thus, whether it's AUS8A or 440A it makes no difference as long as it takes an edge and holds it reasonably well. You don't seem to give XHP much of a score for edge retention, but I trust your judgment.

Thank you for all your research and testing. I have been curious what you educated guess on AUS-10 would be?

[@davidicke2415]

I'm not a knife steel nerd, but I recently bought a Cold Steel Mini Tac Bowie that's supposed to be made of 8Cr13MoV. It's really sharp out of the box but I'm wondering how the edge retention is and how I should care for and sharpen it if there's any special care I should take for this particular blade. It's mostly going to open boxes and packages, though I plan to train with it for self defence and I'd like it to be as sharp as possible for both uses.

Woah im invading Shanghai!

Hey Dr. Larrin, I was wondering if you have any insight and thoughts on Bohler K890? Thank you for your time!

[@Atomsk484]

Would you be interested in looking into and comparing similar products in a specific hobby? How can I contact you so I can explain what I mean?

[@tombrown4683]

It's funny that I was suggested this just when i was thinking of buying a knife that's made with 8Cr14MOV. Thanks for the timely info. I reasoned that it was a proper cutlery steel, after all. Now even more happy with my decision.

[@TheOneAndOnlySame]

Good quality steel, when heat treated by Larrin lol

[@CSGraves]

& sharpened by Triple-B! 😲

[@john0270]

im not sure why people want 1095 blades, when something like aus8 exists.

[@wiz3905]

Would appreciate the results first & then the explaination, that could be broken down as needed? The point of the title is lost 1/5th into your long winded intro. Thanks

[@swannybo1sk8s9]

I dig it I got a tenacious in 8cr13mov and it’s a thinner very sharp edged knife that sharpens up nicely I def want some super steels when I got the cash tho

[@seatroutking7555]

All that being said, what do you recommend as a good SS for home amateur knife makers, you have a very informative channel but as a beginner I foundered in all the technical aspects 👍🏻🇮🇪

[@garethbaus5471]

That is a funny getting 440c when you wanted 8cr14mov.

[@generator6946]

It amazes me that the cheap steel in HYDE putty knives is way way better than ANY other steel out there!! WHY??

[@ttonAb2]

I was recently looking at different methods of stock removal, what are your thoughts on using a cnc plasma cutter for stock removal in knifemaking?

[@musicman6243]

Great job, Dr. Thomas! I want a good edc folder with magnacut so bad, but man they are pricey!

[@leovalenzuela8368]

Why did you throw away those knives? I thought you were super into this stuff? Also, did you thank your viewer that offered to go through all that trouble for you?

[@katanasmith]

Who makes a better educated guess than.you? All your research is so educational. Thank-you.

[@matkhairi6206]

I've never underestimate any Chinese junk they said as a users they normally focussed on a high end steel without realising the metallography facts

[@makenchips]

Very excellent video very good learnings for sharing a lot of good learnings! The common person only knows the user end of these materials if you use long enough there is no Holy Grail in metals play all depends on what you're doing with it. If your application is wrong so is the steel!😊

[@TheChzoronzon]

Thanks for this, that was certainly interesting and without any snobbery. Take a Sub.

[@CerberusForge]

Great video! Would love to see a review and testing of MP35N. I have a few pieces if you are interested.

[@slimtissue7358]

I think the inability to get the correct steel/matching MTR is more telling than any of the testing. No traceability = not knowing what steel you get

[@northmanscall]

thank you for these very scientific test and evaluations. my engineering nerd is happy

[@progunliberal]

Great video, sir. I haven't finished your first book yet, but I didn't realize you'd produced another one! I'll have to pick it up!

[@sunglint]

If loving steel is wrong, I don't want to be right... (great vid as always!)
