Cutting Rope with the worlds best steel until its even slightly dull (REX 121 Spyderco Sage)

[@richardp18]

This is my favourite Guy Cutting Up Rope channel.

[@adx442]

Pete, your videos are an oasis in knife content. I literally smile every time I see a new one available. Thanks for being you.

[@veldennoyes8613]

Agreed 👍

[@tombrown4683]

Also agree 👍 !

[@kylemccaffrey3003]

Yellow t-shirt, we’re in for a good one fellas

[@DEATHMETALRUST]

You said it.

[@Edcreviewer]

I did a card board cut test on mine and I quit after 1100 feet and there was absolutely no degradation so I called it and lost interest and that was on the factory edge. I've never had a steel be it custom or production go 1000ft and not show any signs of falling off, even steels like k390 in a custom I made at 66.5rc 3 inch fixed blade I made that is 8thou bte only went around 900ft before I could start feeling and seeing slight signs of degradation spyderco absolutely knocked it out the park on this heat treat protocol, incredible work for a large production knife!

[@mitaski]

Thank for your sacrifice and happy holidays!

[@leafywiggy4427]

I just love your knife tests. Don't be afraid to re test some of the classics

[@riverrunner23]

Awesome. Mine arrives tomorrow, woohoo. Thanks for your pain in going to the Max with Rex 121.

[@savagewalks]

This steel and their use of it is just the perfect marriage, well done Spyderco...again! Also I loved the cooking video, keep being you sir!

[@kvernesdotten]

For what its worth, I like the cooking videos. But then again, cooking is what got me into knives to begin with.

[@snowhusk]

lol, I got into cooking precisely to have actual reasons to cut things with knives🤝

[@kvernesdotten]

@@snowhusk Ikr! Its weird that theres not more overlap. It would be nice if edc people cared more about feeding themselves (no better preparation than having that skill imo) and the cooking people would take some ques from the pocket knife crowd and realize that we have better things than VG10 now. For anyone who has tried a chefs knife in super steel with a custom heat treat... Theres no way back from that one haha

[@LoreTunderin]

The cat metal scream at the end gets me every time 😂

[@redangrybird7564]

Merry Christmas Bricky 😮✌️

[@DanielReyes-hz1qk]

Can't wait to see the re-Pete test your 17 degree edge! 🤣🤣🤣

[@WillEDC]

🥲🤣

[@leonidasmalta]

REX 121 to the max! 😎

[@tombrown4683]

Sadist !

[@markdale6104]

My arm hurts, i need a nap and ive only watched the film once. Bravo! Well played young man!

[@destro6971]

Hello Pete. I gave you a shout out on the last Project Farm budget knife comparison video and got a whopping 37 likes. I'm doing my part 🤘🏻😂🤘🏻

[@codylayman199]

All your videos are great! Thanks for all the entertainment.

[@tombrown4683]

Classic Pete returns with a vengeance ! Although, the vengeance seems to be on you, Pete. Must have been pretty negative numbers on that last one to provoke this ! Guess everyone doesn't enjoy the Pete cooking show as much as I do ! Thanks for the 'self abuse' for blade steel science !

[@chapmanpreferred1382]

Joining patreon as a thank you for this test/video/effort! Well done!

[@daeholm]

Good job Pete, doing the Lord's work once again. I got rid of a Sage 5 during a knife purge a couple years back and I miss it. This might be a replacement. Good job Spyderco as well.

[@EvilTwinRC51]

That is some seriously impressive edge retention!

[@owlbjoshing]

Rex Harrison approves ☺️

[@firstjohn3123]

KZbin has ended...these cut tests will be continued on the next platform...but the good news is, they ARE shorter than a gov't committee hearing, and more informative.

[@robthompson8285]

....."in a world.....where order has succumb to chaos.....and sisal rope rules all. One man, with a knife.....is humanity's last hope."😅

[@tombrown4683]

Sir, I regret that I cannot give your comment the 10,000 'likes' it deserves. But no doubt in time, they will come.

[@Jeffrose_]

Amazing steel. Amazing video. Next video please, " Sharpening REX 121 ".😮😢😅😊

[@paulmarshall9189]

Cool! Looking forward to the PM2 version.

[@PuReBlOoD3478]

Merry Christmas Bricky 🎄😊 Hey Pete.

[@kpfagerberg]

Hope they do the dragonfly with this steel. Would never have to sharpen it

[@allfather885]

A proper knife video?! It’s a Christmas miracle!!! Love ya Pete, good on ya!

[@DEATHMETALRUST]

Fine I will watch the cooking video

[@jeo1349]

Absolutely INF***INGSANE. Great stuff Pete!!!💪💪

[@Mr.9x19mm]

What a performance. Wow!

[@LazyJones]

Totally getting James Earl Jones as Thulsa Doom "The Riddle of Steel" vibes here at 1:44

[@Lieu10antDan]

Got the 121 Sage earlier in the year. Great little piece. Very, very nice factory edge. Thought it might do well but that's pretty insane.

[@tecnotrog1]

Love my Native 5 in Cruwear...but I may have to buy one of those after Christmas 🦉

[@ntanglr]

You bring us pleasure through your pain in these tests, man. I'm not saying you should hurt yourself in the cooking vids, but who knows, maybe this is the key to stardom :D

[@leonidasmalta]

[@cwooley89]

Haha "Enthusiautist" first I've heard that one

[@FranklinsLighthouse]

Ive been eagerly awaiting this vid.

[@Ash__7]

tendonitis speed run

[@bigglock5478]

Insane performance. May have to pick one up on the secondary market

[@aliw256]

Thank you Pete 😊. That was what I wanted to see.

[@owlbjoshing]

6:54 love glove incoming 😙🧤

[@ericsmiley1266]

Alright, you've convinced me

[@DanielReyes-hz1qk]

You just got an extra view, like and comment on your previous video my friend

[@TheDemocultis]

This doesn't count. You willed it into its dullness. The sheer amount of cutting had you rooting against it. I smelled the hatred all the way in New Jersey 😂😂😂. Fr, good shit man. Can't wait to see what happens after you sharpen it 😅😅

[@procrasti86]

7:08 is where the test begins

[@sswwooppee]

Does cut up sisal rope make good nest material for chickens?

[@krissteel4074]

Ledburites get some pretty weird eutectic mixtures in the ultra-high carbon 'steel' where the alloy constituents are all very close to completely melting and getting some very homogeneous structures. Course the real challenge comes when you're sharpening them as they can have some fragility and might not always support a very acute edge compared to materials that have inherent toughness and flexibility. So if you put your 17deg edge on it, there would maybe have a better ultimate sharpness requiring less pressure to cut, but at the cost of some wear resistance. Like the Rex121 used in cutting and milling bits for machines with obtuse edges (compared to a knife) and they practically don't get blunt being jammed into spinning lumps of metal, they're more likely to just 'fail' in the sense that the edge chips out or some kind of catastrophic breakage occurs when some gronk spins them up too fast or the feed rate is too high.

[@BladeLabMiami]

Welp, my Rex121 Sage came with a factory edge angle of 15°/16°, so I wouldn't worry about a 17° edge. In fact, it might fare worse than the factory edge, unless you go with 15°. Behind the edge thickness was around 20 thou, by the way. Just a fantastic job by Spyderco ... and of course Pete!

[@Spartacus-hc9xt]

Who needs the gym when you have this for a workout

[@johnnyr.bassilious1039]

Waiting for the testing with your edge on it

[@Nudel-nc1cp]

Autistic Slicing Challenge incoming 😄 Can't wait for that refined edge video to be honest. See you again Pete 🙋 Merry Christmas for you and the rest of the folks in this comment section 👍

[@rileyhaven2881]

I have had my Rex 121 sage for a few weeks now, and it has been hard for me to find an excuse for another folder in the pocket! The K390 Leafjumper finally knocked it off it's pedestal a few days ago 😂

[@Pablo668]

Ok, I think that proves your point. Good steel-ish. Doesn't it get a bit hot in that shed? It is summer you know. Btw, your pocket was mesmerising.

[@goncalovazpinto6261]

I had to stop and take a break from the video 3/4 of the way through. My index was getting sore, even through the glove!

[@SOMNIOHM]

_I'd be removing the pocket clip before these extended cut test sessions just for max comfort!_ _Interesting video indeed! Cannot wait to see what it does with a new edge!_

[@andrewb5415]

Real world for me is boxes, and yeah, my Maxamet outshines my other steels. Might have to get one of these. It’s fun to occasionally here old timers say “ that’s gonna dull your knife” to which I can reply, yup, but not anytime soon lol

[@JamEWalsh]

A gentleman and a scholar! Now go nurse that forearm back to health.

[@aaronfisher9776]

I got the frn version.but I'm not gonna try and recreate that one.looked brutal but amazing!!

[@EricBrownWins]

chrono Trigger OST in the first 5 mins. you get one like.

[@Hectorszenshopedc]

Cooking with Gas Mate❤ good stuff

[@IddoPinkas]

Wow. No words.

[@klausheisler5014]

The course diamond wheel on the Tormek T8 is perfect for this steel. 360 grain & a quick strop puts a nasty toothy sharp edge on it & it just doesn't stop cutting. Absolutely disgusting edge retention. A REX-121 shaman would be the T I T S

[@goncalovazpinto6261]

Love these tests BUT... I'm alergic to sisal! If I was there with you I'd be sneezing my eyeballs off!😂 All that shredded sisal 🤐😶‍🌫

[@thefunky_brassmonkey]

Rex 121's power level . . . ITS OVER 2000!!! No way! Thats impossible!! It cant be that powerful!!!

[@mcsquirgle]

Spyderco made our man delirious with their Rex121! What performance! Thanks Pete! I'm filming a sisal rope cut test over on my channel with a Spyderco Stretch in VG10 and can't get it to cut more than 125 times through the rope no matter what angle I put the edge. I have put probably 5 or 6 edges on it by now and it's got me all twisted up. I want to believe I'm doing something wrong and VG10 is really capable stuff, but I have gotten extremely good results from other steels on different knives. Any ideas KZbin comment section?

[@christopherdavisson617]

That's insane. I wouldn't wanna re-sharpen it. That being said a normal person might not have to lol!

[@danielwendell542]

Great video and test, and my money is also in root vegetables and easy to do delicious cooking so. Game recognizes game. Also the orange handle just. Doesn't do it for me. However, the recent "Burgundy" run got me right in the aesthetical solar plexus and I have 3 of them now, and the steel is fun too. Happy slicing, and holidays (whatever they may be!)

[@velvetine74]

I wonder what grit the factory edge was sharpened to? I have been playing with more course grits on very thin flat and hollow grinds with Cru Wear and D2 recently and getting good results with a longer lasting toothier bite on the edge. I've also caught myself a few times on very, very fine grit edges and experienced the cuts you can't feel, until the secondary pain kicks in. Is that relevant, probably not. I just feel it helps me to understand better than I used to.

[@ErnestPworrell88]

Merry Christmas pete! Now i "need" some rex 121 in my life though s90v is doing just fine right now lol.

[@seth_goodwin]

Mine had a sharp but rather rough edge. So I decided to re-sharpen it. I’ve got a work sharp fixed angle unit. I simply could not get the edge to not have micro chips. Any help from the community?

[@oleksandrhr3949]

What is the amount of time you've spent for this cutting and sharpening? Thanks for your time and efforts :)

[@JosephOlson-ui2pg]

I thought at three percent carbon you started making a wrought iron type material thats too hard and not suitable for knives, so I learned more from your video

[@krazmokramer]

My attention span is too short for this steel. I had to keep fast forwarding. How good are the stainless properties of REX121? Thanks for this video Pete!!

[@JohnDoe-zb7dz]

Now for Rex 76.

[@cal1776]

Thank you

[@mccallan2798]

Serious question, do you get paid per word?

[@gregsmith7821]

I swear blind its actually the chopping board that wears the edge.

[@thaknobodi]

A proper resharpening would bring it up about 15% im guessing

[@Tygor3533]

I just got one, it micro chipped cutting a zip tie and cardboard box

[@budthecyborg4575]

Short shorts are still a thing in Australia? That place is like a time machine to the 80's.

[@windowbreezes]

Are you aware of Crucible’s current situation?

[@sloanNYC]

I feel for you on this one. Maybe skip the sharpening? My understanding is that will take even longer!

[@kennymattson574]

I for one love the cooking videos. Do you Pete.

[@prinzvongrorgenwugs7474]

Touhou music!!

[@patrickmccrea3455]

This was great bro very interesting i would hold on to that knife it might be hard to get 😔

[@mitchellerickson9836]

I'm gonna say 2500 with the 17 mirror edge. We gotta see this in a dual grit as well.

[@joelhunter984]

You did "forearms at the gym"..........right.

[@The_circular_square]

People are gonna get bored with their 121 knives never getting to enjoy a sharpening session 😂

[@Edcreviewer]

Once it starts to fatigue the edge degrades and it will definitely require sharpening. It dulls in a very unique way it just stays sharp until the apex has fatigued and then it just kind goes from cutting to not cutting. I made a couple fixed blades in it at 70-71rc and 3-3.5in in size and that's been my experience with it in custom heat treats.

[@betterarmed]

Ok but I like cooking videos too.

[@jasonbeatty9269]

Who’s the pinup on the thigh, Pete? Mrs. Bricky?

[@CarloFromaggio]

Bricky looks good, dental work?

[@_BLANK_BLANK]

I prefer getting my steel carbon from life forms only.

[@bengarver8155]

What alchemy is this?😮

[@brettwarner719]

This is a ridiculous test result. That being said I would like to see a test done with M398. I have heard a lot of edge holding hype for it and want to see it cut some rope.

[@anteck7goat]

Gloves? I thought you were a man’s man? 😅

[@isthebeeflol]

Wear the glove man, it wont make up for the shoulder, elbow, and neck strain lol. Your a machine.

[@citizenkane454]

Need a maxamet vs 121 vs 15v showdown

[@peterise2131]

Yes! I am in for this!

[@tombrown4683]

After the bionic arm is installed !

[@Khrenan]

Iron with 3.5% carbon without anyhting else is cast iron, not steel. Now i wish there were more knives with REX 121. Im sick of Spyderco's FRN scales on 300$ knives. Good vid.

[@tombrown4683]

With you on that point (FRN). While good on some knives, at $300, we deserve better & more hand filling material.

[@mirekbns]

holy crap

[@johnlimpkin]

Strop it and do another 2000 🤣

[@billvan5219]

Woohoo!
