AR-RPM9 Knife Steel Is Not Powder Metallurgy 

Looking at you, Bricky...

Quips as sharp as your edges!

AC-FWMATW-7. Really rolls off the tongue

Go to bed pete.

😆

Facts!

a lowercase comment

Hey Neeves, I dont make things up when I say them. aarpm9 is not powdered metallurgy.

@@tacticalcenter8658 he didn't say you made anything up, not did he even reference you

@@DinoNucci this is for a recent video where I told him aarpm9 was not powdered metallurgy and he argued with me that it was. Dont be a fanboy.

Ha!

hahahaha how I like my steak, not so much my knife steel

Hi, do you remember me saying it wasn't powdered metallurgy?

@@tacticalcenter8658 possibly 😣 Video response loading now

Ahahahah

He's not the only metallurgist. There's some who are exceptionally skilled. Perhaps he has the most clout.

​@@tacticalcenter8658He's not the only one but nobody else is doing what he does variety wise.

@@tacticalcenter8658 Yeah, the important modifier was "that wants to spread correct information." There are plenty of metal experts (and even more armchair metal experts), but most of them aren't using their platform primarily to educate

@@nvalley you can goto bf and find a wealth of information. Theirs also a wealth of books about metallurgy. Not to mention white papers from science direct. All with correct information.

@@nvalley there's actually a wealth amount of correct information out there. People are just too lazy.

I bet he has a huge eggplant.

Nothing gets a nerd worked up like catching a false claim in a subject they are interested in.

Exactly my thought as well. Showing "rare earth" and saying "trace elements" was a dead giveaway. Unfortunately, sometimes that happens even when engineers try to correct them. Which could be why the voiceover was different. The marketing slide was done, but someone caught it before the voiceover was recorded.

watched a second time. Can’t help but laugh 😂😂 anyone want to buy our Artisan collection?? 😢😢

I don’t normally promote on other channels but we made a fun response video to this if anyone wants to check it out 😂😂

@@BirdShotIVI’m going to check it out. Hopefully I get a laugh. I feel so dirty and used right now. Thanks a lot Michael Emler. I bought the Sea Snake because of you. What am I supposed to tell my family now? I can never look them in the eye again. 🤦‍♂️ 😂

Comments being deleted?! PizzA!

Why can't I comment on this without it being deleted??

哥们，M390是粉尘钢（即Powder Metallurgy 技术）。而这个视频论证了AR-RPM9不是粉尘钢……，它用的是介于粉尘钢和传统钢坯之间的技术。

​@@justician9 对的，所以我觉得我朋友和我说的国产M390用的不是真正的powder metallurgy，而是sprayform

China has nothing to do with this. it's all Artisan which is an American company. they ofc source their materials from China and manufacture their products inside China, because obviously China does it better than anyone else can for less money and are highly reliable. This steel was named, and marketed and sold and promoted entirely by Americans & it's made in China for them.

@@user-xf4es7eh9ythey don’t just source their material from China their manufacturing is done completely in China. Like finch knives. To say they just “source” from China is incorrect.

​@@user-xf4es7eh9yI think he was saying it was a bad translation. If its made in china there has to be a translation somewhere even if its an american company

Iirc they also have a Damascus like steel that is not damasteel and it also is not powdered metallurgy. Jim skeleton did a vid on the questioning about that.

@@tacticalcenter8658wow! I didn’t know that. I was hyped to see a budget powder steel. I can’t look at ARRPM9 the same anymore. It’s crazy they sell Damascus steel that’s not even Damascus. I’ll check out Jim’s video. Thanks for the info!👊

I’m shocked but not too shocked. They need to make a statement about this.🤔

At least Damascus looks cool. This on the other hand is just cheap Chinese schlock

@@elgatofelix8917 Pakistani pot metal Damascus is probably the worst. But Chinese Damascus is next in line.

That is exactly what I did! I expected slightly better performance than 9CR but I was underwhelmed. I'd consider Cold Steels 8CR to be better in toughness and edge retention but that is with a sample of one CJRB knife.

It'd probably finish quite close to a near-mirror if it wasn't a factory grind job in a tumbler. Still, I'd hardly call it an 'artisan' product in the examples seen here at least. But hey it wouldn't be the cutlery industry if someone wasn't making at least something up :)

it was obvious it's not. Because if you are going to pay for PM steel, you'd use something better than this. Also the composition isn't even something would make sense to do in a PM form. For the most part if the steel lacks vanadium then there isn't much of a compelling reason to use such a more costly process.

​@@user-xf4es7eh9y but you're not paying for a PM Steel. Check the prices on the AR-RPM9 knives. They are inexpensive.

He says hardness is not effected (thus box cutting) but powder version is tougher

They perform that way with his protocols. Mass manufacturer's will use other protocols, equipment and aim hardness. An example of that is BOS ht will do secondary hardening if a maker wanted it. That protocol was not tested in Larrins chart.

Did he though? He said the steel should be pretty decent and is priced appropriately but the name is just incorrect. They never claimed it was going to perform like M390 or even S35VN. 9Cr is a solid budget steel and this steel is a tougher and easier to sharpen version. Good enough for my $75 Pyrites.

This is why engineers aren't big fans of marketing. There are some great people in that profession, but this behavior is far too common.

That is almost how it always is

Just always say "they claim" before any statements about stuff you didn't make.

😔

Bingo

💯😂

No need to get personal

Some of us actually use our "nice knife" ...lol life's short

Yeah, I like the steel. It looks nice.

@@Funkdoctor yeah it looks good.

It has less edge retention than 9cr18mov. The first batches of aarpm9 had issues due to heat treat protocol. Outpost76 has some info on it.

@@tacticalcenter8658 Sounds more like a manufacturing issue than an issue with the steel itself.

@@arthurmoore9488 the protocol was changed and the aim hardness also.

Man will never outgrow D2

Unfortunately the OES wasn’t calibrated properly to detect Mithril

@@KnifeSteelNerds When a 'fictional' steel meets science, does that make it Science Fiction? ar ar ar. But seriously, keep up the good work. Also, please recalibrate the OES to detect Mithril.

​@@KnifeSteelNerds I expect Mithril by the end of your career.

@@KnifeSteelNerds Maybe it can be detected through testing the hardness. Mithril is "hard as dragon scales" after all. You just need to test the hardness of dragon scales first to establish a baseline. Simple.

​@@Thexaiosthe dragon scales are measured on the rockdwell scale

Which one did you get? CJRB More Maileah is one of my favorites for edc, quite bummed them lying about the steel. I think even if they said "spray formed" in their marketing for the steel, that would still be quite successful and interesting for a buyer, and set them apart from other companies. Albeit, not to the same extent as calling it "powder"

@@snowhusk Agave, aluminum handles. I took it out with me today because of this video and used it on a garden hose repair. Worked like an absolute champ. Nice, clean cut. No complaints whatsoever. Oh, cool. I have their Crag, too, which is sort of a bigger, regular flipper version of the More Maileah as far as the cleaver blade (but it's D2). Also a great EDC. I guess I don't feel so "lied to" about it because I didn't think it too reasonable to expect real powder metallurgy-level performance out of a $40 knife. I mean, it will be great when we get to that point, and I think we will fairly soon. This is kind of half-way there.

There's nobody saying you cannot like the steel or continue to purchase knives made with it. He's pointing out the disingenuity of the claims made by CJRB, either intentionally or unintentionally. Now you know what you are getting, which in my opinion still isn't a terrible steel, just now overpriced (again, my opinion) when Nitro-V and 14C28N blades are in the same price range.

When the customers are ostensibly making their purchasing decisions based on 0.3% elemental composition we’re kinda asking for it 😂

This reads like marketing just didn't understand the specs. You see it in many industries.

it's not "Chinese marketing" genius. Artisan is an American company that is owned and operated by Americans in the United States. So what is it with American marketing, there's definitely greed and ""hopefully our customers are gullible enough to never find this out." I'd bet 10 grand you dont even have a passport and I'd be shocked if you finished high school.

That’s all marketing. Look at Nike, the sell $5 Chinese shoes for $200 and it’s the greatest technology ever!

Artisan is an American company run by Americans. Finish high school.

I'm much more irritated that they lied than that it isn't a true PM steel. If they had just come out and said, "hey, we have sprayform 9cr18 in these $50 knives!" I would have been jazzed.

@@InsipidMoniker You know there were several E-mails and meetings between the marketing department and either internal engineers or the steel company. Where the technical people tried to explain it, and marketing didn't listen. Either that or they got a marketing brochure from the steel company and completely misinterpreted what it said. Why? Because they said "trace elements" instead of rare earth elements in the uncut voice over.

Yes, but the people selling/advertising these products shouldn't be using ignorance as an excuse. Lies? Half-truths? There should be zero tolerance for any of it. If they want to talk big on social media they should hire an actual metallurgist.
