M398 - Upgraded M390? Steel Testing! 

Spyderco should send you their entire catalog each year. Your testing and opinions have sold more than a couple to me!

Spyderco needs tot make an 18/10 pot steel MULE...

I am just wanted to state how much (a lot much) I appreciate your lack of sponsored host ad reads... I'm always impressed by the genuine, honest work you put into keeping it fair and consistent - and I routinely crack a smile upon hearing the newest video's choice of musical score, too. I am excited to see your upcoming addition to the collective knowledge (as well as to your considerable personal collection of data), by essentially establishing some oxidation testing benchmarks with modern carbon steels. But no pressure, Pete - we both know how expectations can sap the enjoyability from once-beloved activities. If it's next year - or never - I'm good with it. I enjoy what's here, and I try not to fall into the habit of focusing instead on what's just around the corner. I'm just happy with whatever you decide to share, whenever you're inspired to create. We love you, buddy - and congrats, by the way, on being noticed so favorably by Sal Glesser himself! ... Maybe put a word in with him about making more 15V knives - so we aren't stuck with the scalpers if we aren't lucky enough to score one during the minutes of availability before they're all snapped up?

Forget the sisal rope. How many huusk knives can it cut through and still glide through a held sheet of paper?

Haha! All good Pete! I made those kinda goofy scales myself (so as not to kill your hand)! It turned out my first batch of mules I sent you had a bad wire edge (lack of sharpening knowledge at that time) and no hand-destruction happened. I should have put those scales on the MagnaCut Mule of recent, probably would have hurt your hand less than that janky paracord wrap. I just had no idea it was gonna cut 1500 times. Feel free to get through all your Mule testing first bro, I can wait a couple extra weeks for the knives to come back. Great video.

It was very nice to see you give preference to your family over knife hobby. Thanks for testing M398.

Very pleased that Spyderco have started working with you. Although their knives tend not to be my style aesthetically, they're by far my favourite company in the knife making game -- because of the attention they pay to the community.

Glad to see you back with an edge retention test! You da man, Pete!

Still loving the innovative use of the green screen as a..green..colored screen. It's a meta commentary on the unsuccessful attempted conquest of technology over our osb roots. I appreciate your videos over the years, hope all is well down there.

Spymyto just ordered. Half the price of the Slysz Bowie. Micarta on one side, titanium on the other. Peak stainless.

More bricky !! Thanks for doing some testing this steel,have been waiting for someone to do it.

It’s good to see a test of this one!

I was very interested to see how M398 would perform. Thanks for the video Pete. Good stuff 👍

Steeltoes did some testing and got around 550 with a blunt edge. Then he did this. Today's testing with a 10-11 dps super vitrified triple b stone at 1k achieved 720 cuts in my testing today. Surprised not many gave this steel a fair shake when it dropped 4 months ago. The Mules are 64 HRC

I love your simple approach to knife testing. I cut rope and boxes most often. You give me the best idea of what to expect from my knives. 😊

Never miss one of your videos they are just great Pete, thanks for the effort. And hey congrats on that mule sent from Sal himself, that is just priceless and awesome, it speaks a lot about the quality of person Sal is, next you'll be designing your own knife, which I'd definitely buy.😁👌👍

Eight years of carpal tunnel, got a love it

I always find your videos helpful and entertaining. Thanks

Good ol times when I see a sisal rope test on your channel Pete ! Thanks for another great video

Nice! Been digging mine since I got it. Still very sharp after random uses over 4 months or so. Idk how strong it is and I would be scared to hard use it but as far as reasonable uses it's great and like I said VERY sharp still. Impressed, especially for the decent price here stateside. Only complaint is the spyderco leather sheath... kinda sucks and fits oddly. I'm gonna either make my own or commission a kydex one soon Edit: forgot to ❤❤❤❤ for chocobo music

I love Spyderco knives. Thanks!

Love the green background, it works really goes really with you white tshirt Pete, 👌🏻👍🏻! Great test and a very relaxing video review to watch. I recently purchased a Magnacut bladed knife. On the factory edge it developed one micro chip after whittling Oak for approximately 25 minutes, no rolls, just the tiniest chip, virtually invisible. M390 on the other hand chipped out a little worse, a larger chip, no rolls, and this was after approximately whittling the same Oak chair leg! lol! Well I felt that I might not removing the right angles from the chair leg might be in contravention of the Geneva convention even though I agree with your " Tactical " advice about getting a few good hits in the old angles! Great vid, well done, and keep that unevenly over developed right arm of yours in optimum condition with regular maintenance mate! Best wishes to you and all of your family and loved ones Pete, 👌🏻👍🏻!

I guess by this time Pete has developed muscles from all the cutting no other human has.

Still steel testing. Love it! 😊

I'm so glad I got my m398 mule. It is my food prep knife.

GOLD . PURE GOLD. GOLDEN MAN...❤😂 M 398 HAS CROSS MY SCOPE. I was just testing m390 in the Fara MKM.. Sleeper

I hope you aren't demonotized for using a red marker on the blade.

I live down the road from spyderco and still haven’t taken the time to have a visit

Pete...thanks mate. Tsprof tip zero to the clamp holding arm then place on top of rod holding stone with stone at halfway point on edge. Center clamp attachment would be very helpful. 15 bucks on gritomatic. Dont buy the tsprof one for a 100 bucks or whatever they reaming us for currently. Cheers mate.

5:52 Nice

I love Mule Team knives. I have several.

I'm hoping you test one of those 15v Sydercos one day.

I considered purchasing the M398 mule from the Spyderco factory but seeing the toughness of M398 is lower than M390 I decided hold off on buying it. However, I am looking forward to the “AEB-L” mule from Spyderco.

Can you please do a steel testing with damasteel?! And of course would love to see corrosion testing with damasteel too! Great vids

I didnt expected the ff8 battle music :D

Thanks for another great video, I think m398 is another great steel. However living on a boat means its vanax or magnacut for me. Im Still offering sanctuary for one of your poor long suffering magnacut mules pete. Cheers

showing the edge reflection over the "how to care for your husk" lol

What a great father!! We luv ya Pete !!

steel testing time is the best time! Also, friend, zip your fly!

AEB-L coming out in 2 weeks, rest up that wrist!

Two questions: what do u do with all the rope cuttings? Have you ever cut yourself during rope cutting tests? Repetitive motion injury aside, you always look very focused, therefore very safe. Thanks for the excellent infotainment!

M390 was the super steel for 2015 there is a new one where they added titanium

Well done friend

Love the FF battle music xD. Wish they would do another retro FF. Oh and Chocobo music xD. 2 good. Also seeing how tough that rope is b4 you go to super speed. That looks exhausting...

Be nice to be able to fiddle a little w the steel recipe and hardness. The m398 w a percent niobium-for fine grain and a little nitrogen for same -might improve toughness. We need a ready bake oven for steel dated reference

So. The hardness of the carbides isn't going to be what would cause toughness issues at the edge. The volume of the carbides (the ammount a given steel has), and the size of the carbides (like d2, vs cpm d2), are going to be the real factors that play into the toughness. Which is why the non stainless (or semistainless, as i like to call them) tool steels are the overall best performers with a toughness/wear resistance balance. And its the reason magnacut is such a big deal, it was able to get an only mc type carbide microstructure, while also being a stainless steel. Therefore having a lower carbide volume, and raising the toughness. But still having good wear resistance because the carbides are harder.

Great job, Pete! And thank you for that!

Did Pete just say Sal hooked him up? As in Spyderco’s Sal?

miss the "To The Max" videos. Would love to see a 15dps run!

Kind of surprised you've never done m2 steel

The Rex76 mule has tested 69.3 hrc. 😮 which is crazy

Dude, have you ever seen a mule, they aren't ugly, they can be really cute.

Next we need of video of breeding chocobos

Thanks for the video Pete.

Pretty fucking cool Spyderco sending you knives👍🏻👍🏻

Great video like your reviews and blade steel testing

Zipper, Pete.... zipper!

I've been impressed with m398. Got a custom in it at 64hrc and ground to 0.007 and it's performed better than any stainless steel I've tried yet in holding an edge without needing a touch up. It even beat out Elmax at 64-65 by Cultrotech though some of that might be to blade shape. I still haven't used s125v yet (sold the only knife I had in it before much use but it was the hardest knife ever to sharpen) or s90v (my favorite high carbide stainless) with a custom heat treatment to see where it ranks. Going of tests it's about the same as s125v at the same hardness but slightly different feeling. Will be interested to see how it does with Gabe. M398 and magnacut are both pretty new to me but I've been enjoying both and they're really moving up my favorite steels lists.

Bunnings or wherever you buy your rope from must love you lol.

Thanks Pete!

Thanks Pete.

Good morning. do you know the brand casstrom? their sleipner combined with a true scandi grind are great for the outdoors.

Interesting M398 Greetings from Switzerland Pirmin 🇨🇭

Australia man wins AGAIN…jeez. Anyway you could do an “it’s dangerous to go alone. Take this!” With a Japan inspired huusk knife ?

They keep adding numbers to the steel and the price tag. And we keep buying them. We all know most super steel knives are used merely to cut open the packaging of your new super steel knife. It's madness.

When they say it is nog tough, does this matter in a folder or is is tough enough for day to day use?

Hi, can you compare m398 with k390 in matter of toughness and edge retention pls?

I really wish they'd redesign the mule and get rid of the hump on the back. The ergonomics would be so much better (IMHO)

Thanks Pete. Spyderco lost my interest several years ago. Their innovation is about as exciting as a trip to the gas station. Your vids remain excellent.

@CedricAda When are you (if ever) going to test some AR-RPM9? Curious how it compares to standard 9cr.

You look super good! You need to post your excercise routine, very curious

Hey Pete, what ever happened to the other half of your testing cutting board? I know how and when it broke but I was thinking maybe you can get the other half to someone so they can continue on your style of knife edge testing on the same brand of rope for similar-ish results. Just an idea

Very telling that magnacut with less chromium is more rust resistant, and does a similar amount of cuts with less carbon and vanadium.

“Whacked off almost immediately”. I hear ya

Wait until you try Spyderco Golden USA 61-62rc m390/20cv or Reate 61rc secondary hardening m390. They should be in the 800-1000 range give or take. Everyone is doing m398 a bit soft, not sure what the mules are at. In anycase, Reate uses liquid nitrogen and 3 tempers in the 500c range. This basically takes the chromium and instead of using it all for stainlessness, converts them into larger and harder carbides. This allows them to be in the 60-61 range and still get high performance at a lower rc. Where as Spyderco is most likely using a different austenitizing temp and most likely a shorter soak time, plate quench, then Ln2 and low heat temper(s). Aim for a higher rc than the other brands, as they are aiming for 62 average. So Spyderco will range from 60-62. 60 being better than other brands 60rc but not really that good for m390. 61-62 are really where the golden protocol shines in testing. The other factories Spyderco uses, Taiwan, Japan, Italy etc are not using the same protocol as Golden USA factory. So performance is lower in comparison, even if they are at the same rc. For example Japanese m390 is often around 62-63rc and its performance is lower than that of the golden m390. Perhaps this is due to grain growth from longer soak times? Hard to say because Spyderco doesnt usually disclose their protocols.

Babe, wake up! New knife steel just dropped!!

FF battle music so good for this

why did magnacut get twice as many cuts as cruwear pm2?

Good info. Thanks!😊

i wonder how much it takes to own exclusive bladesteel/sprint run rights for a certain Spyderco steel. If I were a smaller knife store owner trying to grow, this would be a no-brainer investment for sho. all of your sprint runs literally sell out within a half hour, and your brand becomes a collector's watch-list, Spyder-affiliated name in the market. hmm

“Fluff off and jagoff“ 😂

Great video, thanks.

"The only people that are going are either huge collectors or giant nerds" and scalpers

hi, which would be your choice, Magnacut, M390 or M398? Can you put them in order #1 the best and #3 the one you prefer the least? Thank you

M398 reminds me of S90v

Given how much higher the content of all the "nice" additives is in M398 than in Magnacut (Cr, Mo, V, W), M398 is probably a lot more expensive than Magnacut.

Bloody great!

Pete is trying to get a new demographic. Mule and zipper . Naughty man

Sounds like a minecraft character is digging in the background

Witch sharpening tool is this

The local home improvement store must see u coming for that rope when u pull in the parking lot 😂. Hook me up with one of those mules my friend trade ya though the shipping probably won’t be cheap because I’m in Merica🇺🇸

If I could cut as fast as you do I am sure that I would lose count early into the cutting.

Do i review on a fallkniven Modern Bowie

But how does it compare to a Huusk knife?

But... how does it compare to a Huusk knife?

Spyderco rocks brother 💯🤜🤛👍

Go team!

Nice, vey nice.

Man now I want to play FF7.

Have u tested D3V?
