I liked the transitioning at 11:53. I recently started following your channel and have gone through most of your videos already. I appreciate your work and passion and your continued improvement in presentation and editing.
This is what sets your channel above the others. Been waiting for this comparison. Great video!
Hearing that rpm9 was basically powder formed 9cr was like receiving a “budget” gift from the gods. 9cr is a highly, highly under-appreciated budget steel. It holds an edge, isn’t too picky about edge geometry, strops back and (most importantly to me) sharpens up to stupendous levels of aggression for a stainless steel. Like any steel, rmp9 still needs to be processed correctly but artisan seems to have dialed that in pretty well. My Ria and Scorias exhibit many of the same qualities I get from the 9cr Civivis and to be honest, that was all I wanted from this steel, personally…
Not even powder but spray form 8crmov. Spray form is a little better than ingot steel but not as good as powder metallurgy.
Gotta give CJRB credit, they are pulling out decently done D2 and their RPM9 (not the first couple runs of it,, they had it vastly to soft that stuff was a nightmare to sharpen and edge retention was a joke in talking about once they dialed it in) is really killing it in edge retention per dollar. The rpm9 crags at 35 bucks on Amazon are absolutely hard to beat, your getting a solid design and the edge retention your getting for that kinda money is hard to beat. From my testing current rpm9 models are out cutting kizer n690/VG10 models by a far bit and at close to half the price it's a really superb value in a steel that is pretty damn good across the board. It just don't like to be polished, 400 to 600g and it will shock you at how good it is, taking it much more then a 1000g and it starts to slick off really quickly but 400 to 600 the Bite is excellent and the overall performance hits well above its price indicates.
Really been enjoying your videos thanks for all the work you do in the contributions to the community.
Just the comparison I was looking for! Thank you!
I've had the D2 version for a few months now and comes wicked sharp out the box and easy to maintain. 👌🏼
I love these videos! Thanks for doing all the testing.
I'll take "bro science" over numbers on a chart any day. Thank you for taking the time to do this. I enjoyed watching. 😎👍
this was an all around excellent testing video on a steel battle which I have been anticipating for a while. The results are really favorable, and its so cool that we can get these steels, on knives like these for the price! its amazing, and honestly, these are a couple of knives where its worth it to have both. I mean...just look at em. one is the quintessential work knife, and the other is great for an evening casual carry.
Thanks and yes I feel the same way about both of them. They are such a bargain and if you haven’t tried out the CJRB Feldspar it’s one of my favorites from them and you can get it in D2, RPM9 and blade hq has one in s35vn 👌🏻
great video.thanks for the comparisons on these.cedrics channel really is awesome 👍
Great video. Thanks for showing what some real world uses the effect on the blade would be.
Sweet! Been waiting for this!
Fabulous testing! Thanks!
I was waiting for you to pull some rebar....lol. I really enjoy watching you do the physical knife testing....you do It better than anyone on RUclips! Keep up the great work 23 👍
He threw a kitchen sink at it between steel in the knife and copper pipe lol
I haven't had to sharpen my Sea Snake yet and it's my only AR-RPM9 blade so far. I like how it fared on the Crag in this test. Even though I'm not a huge cleaver fan, it looked like it did a good job on those tests in either steel. It might be worth a try and then I'd have a second knife in RPM9 too. Hmmm. 🤔 Thanks, Nick.
The combo of these steels and your sharpening makes for a good cutter.
I was wondering about the new alloy vs D2 for my daughter's Christmas present. This was very helpful in that they are similar performance. Thank you. Quite interesting.
Great job thanks. Really helps.
✌🏼🦁
I had a D2 crag with gray G10. A beast of a folder and value although i found it a little portly to carry and traded it off for some ano work. Loved watching the testing and may try a micarta feldspar in ar-rpm9 as im curious.
Great video Stassa23!
wow stassas your the man ,super great content-this is what a channel should do when they say VS
Great side by side! Good to know their proprietary steel is actually good.
Thanks for the awesome review 👍🏼👌🏼
Thanks for the video! Very helpfful
Loved the sound of the card board when sped up lol
Really good video. I’m trying to decide between this and the Kizer Sheepdog version in the same price range. Mainly it’d be a hard use folder for keeping in the truck
Just ordered the rpm9 version. It looks like a racecar and I've heard it's very slicey. First budget knife that I've wanted in a while.
Thanks for the comparison! I picked up the rpm9 version. I will say it sharpens up much easier and cleaner than my D2 blades.
Love these videos. Kind of proves normal use no need to spend 100's for a decent knife
Excellent review!!!
Good testing review. Harder use than mine would ever see.
I prefer the AR-RPM9 due to the fact that it is legitimate stainless steel, while D2 falls short @12%, having sharpened both, the AR-rpm9 is easier to get a good edge, the D@ is tough but troublesome to sharpen for me.
You are an outstanding reviewer!!
I hope you continue doing this test on other blades, principal on the news ones.Thanks
FANTASTIC, I love em both, bit I would choose the black.😊
Thanks for the comparison i was wondering if aarpm9 was better tha d2.
I’ve got 2 knifes in the AR and been really happy with it
As far as better not sure but feel like it is
Definitely impressed 💪
Good real world test. Basically, it looks like budget steels can be pretty darn good and unlike some of the more expensive steels that will hold an edge longer, you don't need to send them back to the factory to be resharpened.
If you own knives, you need to learn how to sharpen them. Bunch of good enough sharpening kits out there now that aren't too pricey.
@@jtoker9758 Always good advice.
First time ever hearing of this brand or steel but I gotta say they look nice are they solid and wiggle free? do they line up ?what's the size of anchor screw shaft ? Price seems good oh and is the shaft screws real on both sides ? Want to check closer before purchase.
Awesome review 👍👍
I have the D2 KnifeCenter Burlap micarta exclusive. I had some issues with the lock up at first but it's a great knife for sure! Thinking real hard about sending it to BJ Hill and let him do his thing to it! Flipper delete and spydie hole, his whole deal!
Also def enjoyed this comparison! Thank you for the hard work!
Pete has millions of hours playing video games so he's practically invisible 😆. Just gotta say Stassa you and Pete are great and your channel means a lot to me and so many. Thank you. Hope you and the wife are well my friend and God Bless!
Thanks Kyle I appreciate your support 👍🍻
I just bought the rpm9 and the D2 with the contours I plan to swop handles and hardware it should look good I guess.
I've got a handful of d2 pocket knives. I will admit they do rust and they are hard to sharpen but they're tough as nails. This looks like a good functional blade and for the price it's pretty great.
From what I'm seeing on the composition it's basically a powder steel version of 9cr18mov. So smaller more consistent carbides do to it being powder steel. I need to get one lol
Can I send you a Zero Tolerance 380 to get sharpened if so how much would it be I live in Bogalusa La.
I see we use the same size air filters for our home"s central air.
I haven't had any luck with the new steel in two different knives, this one got sent to me by mistake as I ordered the D2 Crag and I did order a Scoria in AR-RPM9, But both were below Rc 58 in hardness and I sent them back. When I got the D2 it was 59.8 Rc which wasn't great, but ok.
If you think that is bad try carrying a surgical steel bladed knife like me for 2 years because it's all you can get. I just decided to upgrade to the kicker with d2 steel because I use the knife then have to sharpen it and I can get this shaving sharp freehand sharpening so I know a better steel I'll get better results.
How do you think they compare to the kizer sheepdog ?
FF to 24 min mark. I'm just impressed the pvd coating held up beautifully, most Chinese Knives must be enamel 😆
Great Video
I have not experienced a problem sharpening the ar-rpm9 but haven’t taken it past a toothy edge yet. So far I’m impressed with the edge retention. Nothing scientific, just gut feel ED use. I haven’t sharpened through any potential factory belt edge heat treat damage yet, so it might get even better? For certain it isn’t Fidget Toy Steel like 14c28n. It way outperforms that.
Спасибо, было интересно, и удивительно, что D2 не разгромила AR - RPM9 в сухую, а оказалась только не много лучше.
What progression of stone and stop did you use. Those knives really took well to it.
100-1000 diamond 1200-1600 ceramic 3.5 and 1 diamond lapping film
In your opinion, are these "Heavy" knives?
Great video Stassa!! Maybe another everyday item that you could add to the test cuts is zip ties!!✌️
Send him some. Costs money. Help the dude out
@@theknifeconnection9571 it's less than $5 like everywhere for 100 zip ties, you crazy
Did you sharpen these yourself?
We should all think of a productive way to test blade edges and cut something that needs to be cut at the same time
Wow the copper shaving is brutal 😂
Awesome
I think I’m about to order the Carbon fiber one
I bought this one several weeks ago. The detents are set so well on it I thought they were magnetic. Crazy sharp blade too. There will be blood, and it will be yours.
Looking forward for these 2 steels to go neck to neck! It seems like not much difference between the two.so which one is better? Cedric and ada doesn’t do many videos, I love his channel!
The rmp9 is MUCH easier to sharpen and can get to a higher level or sharpness due to being a CMP Metal
@@mitchellspringer7025 I would definitely choose it over d2 but that being said, well treated 9cr is actually perfectly good steel
@@snafuequals I agree! Civivi 9cr has been stellar For a 9cr but their 14c28n is my hands down favorite steel for the price and quality
Дякую за порівняння!!!!
Bro Science 😂
pretty sure u just sold me a Feldspar w/ the deep red Mic' key grippie.. u prob know the one i mean lol ;)
Pinche Stassa!
My g10 cage lock only weights 4.6 ounces it is not 6 ounces. I have the silver carbon coming in today 🙌🏻
Yeah if I said 6oz it was definitely a mistake on my part sorry
i go for d2
I appreciate your spending the time and effort to do this kind of testing. It really gives us a general idea of what we can expect out of real world use. I have a lot of respect for you, Gerald, Tom, and Pete for doing what you guys do for us.
#22aday
If you don't know what that hashtag means, google it, then help spread awareness of this heart breaking statistic..
For real. This is some hard testing. I particularly dig the aluminum strike results. I need corrosion resistance and an edge that can take an accidental clang against a boat.
Man you got that right on #22aday. It's inexcusable and awful. These wars need to end.
I'm well aware of 22aday. It's not only the veterans that suffer but their families as well. In the small community that I live in a veteran succumbed to the epidemic of opoid abuse. The next year his brother committed suicide at his grave.
CJRB does a lot better with D2 than Civivi, my mini Praxis in D2 dulls out real quick.
D2 is older tech.......14c and RPM9 are newer and better.
Surprised on the price point of their D2 steel version. Less than $40 for what seems to be a well made D2 steel folder? That's very reasonable.
The recoil locks are awesome too. I got one. And it's fun to play with too
I bought a CJRB feldspar in D2 a couple weeks ago. Nearly razor-sharp from the factory. Haven't needed to sharpen yet. Very happy with the ceramic ball bearing opening and the quality is great for this price. Could compare to Benchmade. Also with a coupon I picked it up on Amazon for 28 bucks. Several versions of CJRB have this option. I'll buy more.
@@PureCountryof91 not all of them are recoil locks tho. What’s up with that?
@@49giants3 wish I knew. The way a recoil lock works is very secure and extremely solid.
I'll take AR-RPM9 or 9cr18mov over any Chinese D2 , also both being Chinese I really doubt they are over 59 - 60 HRT
Ill take any chinese D2 over 9cr18MOV,been using chinese D2 made for years and im happy with it
Well funny think is a lot of guys complains Chinese D2 rusts more. Well part of this is indication of biger HRC values.
It's simple- more HRC means more Cr in carbides where it have no impact on chemical stability.
I think D2 is better than thier 8cr spray form steel.
I just wanted to be comment 100
Hey I’ll take it 👍 thanks for checking out the video and thanks for the 100 comment 👊👊
I think the dislikes are the AR rpm9 lovers who thought it would do way better then d2
Какие же они страшные
outpost dude seems like he rode a short bus then again so do most knife bros
