I can Freehand sharpen REX 121, and so can you!

[@NeevesKnives]

I will say you have some 🥜 doing edge retention tests with that many cuts in rope. People have no idea the effort it takes to accomplish i appreciate that you do tho, incredibly results btw

[@robfahey1349]

Sad part is he speeds it up to save people from being bored and most don't realize that it takes him longer doing the cut tests than it did to sharpen it. Although watching this video I got to thinking and not sure if its been done if anyone has shown strops with different compounds / emulsions under high magnification think that would be interesting least to any experienced sharpener or one who cares.

[@Ingeb91]

​@@robfahey1349 sounds like a job for outdoor55

[@stevetomayer9412]

Outdoors55 does a lot of excellent sharpening with extreme magnification video if your not familiar

[@kerryrwac]

Pete should do a grip strength test to see if cutting all that rope with one hand makes a difference, and if so, by how much.

[@robfahey1349]

@stevetomayer9412 yeah i follow him and watch alot of his videos, I don't believe he ever focused in on strops I know he has done alot with stones and grit contamination etc

[@NeevesKnives]

Looking great Pete! Looks like you are working out if so keep it up. Nobody else is going to take care of you if you are not going to aside from some bedside Nursing on the way out. Well heard you say you were hitting shoulder's at gym so its obviously working since i started the comment at the beginning 👊

Loving the Rex 121 videos, it's a steel a lot of us knife nerds are curious about

[@ryewaldman2214]

Hi Pete, this really is an awesome video that demystifies "super steel" sharpening. It isn't difficult nor prohibitively expensive to sharpen with some informed choices in abrasives. Thanks for this really well documented video showing the process and the macro/microscope captures of the blade edge after each phase of your progression. 1800 cuts is an incredible result that shows proof of performance. For somebody who is always extremely modest regarding your sharpening skill, it is obvious you are good at it. I can't think of anybody that has a broader range in knife sharpening experience that you between all of the various systems and styles that you've presented on your channel, along with the fact that you've sharpened every cutlery steel known to man AND have then tested those edges I couldn't really tell because of the fast-forward speed, but when you are about finished with a grit and ready to advance to the next phase in your sharpening sequence, it is really good practice to really lighten up the pressure on the knife for a final series of passes. that will help you with burr minimization. Outdoors55 has some pretty good videos recently showing and demonstrating. To my somewhat untrained eye, your ragged edge on the "medium/coarse" and then the more refined, but with what appears to still be some visible burr after your "fine" sharpening is indicative that you're using pressure to make sure you are cutting into the steel and maintaining constant pressure for the entirety of each phase of your progression. Your scratch pattern looks deep to me. If you lighten your pressure as you finish each stage in your progression, you will start to refine the scratch pattern and leave the burr on the edge much smaller for a given grit size. This will result in less effort required at the subsequent finer grits in your sharpening progression and help make the final stropping steps easier. Just a suggestion.

[@glockgaston2922]

Pete thanks for all of your work in making these steel/edge retention videos it’s really appreciated!!!

[@just9911]

I’ve had excellent results using 3 micron gunny juice on the soft rough side and 1 micron gunny juice on the stiff smooth side. I feel like I’m less likely to over-apply the spray. The 3 micron seems to do a really efficient job bringing back a used edge. Previously I would opt for a 20 degree microbevel from a sharpmaker to maintain my edges between sharpenings, but lately stropping at 17 degrees seems to be working just as well. I really love your content. It’s impressive to see your results and it keeps me motivated to try different techniques and equipment.

[@timwagster9458]

"I do this by choice, I'm no one's prisoner". That is exactly what a frightened prisoner would say. Can we get a team together to break Pete out? He is being tortured and needs our help. 👍🏻😁 Thanks for the vids!

[@thomasschowalter8475]

I enjoy the super in depth series on this one steel. Your videos are very insightful but they’re also my favorite background noise as well 😂😅

[@dongammilljr.9605]

[@npenick66]

Interesting steel. Wish I'd picked up one of Creely's when he did his rex121 batch.

[@tombrown4683]

Definitely the interest is there even though I will probably never buy a knife with Rex121 steel. Happy with my K390, XHP, Cruwear. Even still use one with 440C & have too many on D2. But academically still interested in your cut tests. Like Outdoors 55, Alex is sharpening guru. Met him, cool dude !

[@The_RC_Guru]

The worksharp field sharpener is just that. I have one but it really sucks as a main sharpener because it’s so small.

[@greypant7204]

Worthless stuff, not sure why so hyped. U can just glue two diamond plates form guided system together. Strop there is usless, ceramic is round and useless as well 🤷🏻‍♂️

[@The_RC_Guru]

@ completely agree.

[@victoralvado3407]

If I'm not mistaken, Mr outdoor55 recommended to strop in the opposite way that you're doing, like starting from the tip so the scratches done by the strop follow the ones done by the stones. Love your vids keep it up 👍🏻

[@CedricAda]

Good tip!

[@danielduvall4154]

I love to hand sharpen my knives. Its kinda an addiction for me. Its just so calming to do for me.

[@andrewb5415]

I picked one of these knives up after your first video on it and I will say it’s a different edge somehow than what I’m used to. Normally when I get a new knife from spyderco or chris reeve they will shave hair off my arm so well you’d think you could shave with it. The sage was sharp, cut a few hairs, but didn’t make me think I would want to shave with it. But when I cut paper, cardboard and tape for the first time , wow. Great knife so far and glad to see I should be able to sharpen it with things I have 👍👍

[@greekveteran2715]

My favorite knife and steel to sharpen, is the Vanadis 4 Extra on the TRC Mille Cuori. It takes an ultra sharp edge, even if you use just sandpapers,similar sharpness to the edge you can get on Carbon Moras! Suprisingly easier to get it that sharp,than I thought it would be. Perfect heat treatment and probably my favorite steel out there.

[@davidheath2427]

I have a big like for vanax. Could not believe how well it stroped. Nor how long between sharpens . And a lot easier to sharpen than I expected.

[@MrLosbandos]

New viewer and subscriber here, just have to say I love your work and style. Super interesting and funny.

[@r.awilliams9815]

I wouldn't want an EDC in REX 121 due to its lack of toughness and my tendency to be hard on EDC's, but I'd sure like to try a Japanese style kitchen knife made with it.

[@daeholm]

I think it's safe to assume at this point that Pete has cut more rope than anyone in history. What job or profession would require someone to cut as much rope? Congratulations Pete on this great achievement.🎉

[@gbeasley3424]

Cedric As you were able to microchip the Rex-121 and Cruwear against a safety pin, you also now need to do that test with Spyderco CPM-15V BBB steel. The reason for this would be to see the comparative durability of the three steels, and since CPM-15V BBB is right up there in Rex 121 Territory in rope cuts. What say you, since you do have the steels to do this durability/toughness test???

[@oscr_zen]

needless to say, I cant wait for the next video!

[@jimbo92107]

Have you considered stuffing some large, decorative domestic cushions with all that cut rope?

[@achimgeist5185]

Rex 121, PM60, CPM 15V, Maxamet and other high-alloy steels, real monsters in terms of wear resistance, are all easy to sharpen, you just need diamond plates, they don't even have to be expensive (more expensive ones last longer and are more homogeneous in the grit). So diamond plates or CBN plates and a strop with diamond compound is the answer to sharpening top tier super steels. I use diamond plates from Atoma (I also have Naniwa Diamond Pro stones) and diamond paste from Stroppy Stuff. If you want, you can also use a hard ceramic whetstone for honing (not sharpening), I use my Shapton Pro 5000 ceramic stone, it is very hard, feels like the blade is gliding over glass, but it does its job.

[@SnowblindOtter]

Have you tried stropping on a paper backing rather than leather? I typically do my stropping with 3.5 micron diamond paste on some smooth paper glued down to a piece of float-glass. With that I can get an edge on my Aus8 daily carry that stays shaving sharp for about 2 weeks of pretty constant use.

[@allfather885]

PETE, PETE! Did you know that Huusk are now advertising that their knives are made of “4CR14 Stainless Steel” and that they are selling “whetstones”? Can you PLEASE get one of each and do an update video? I need a good laugh. Also, have you ever tested a steel called “SLD-Magic”?

[@Saltade]

thank you

[@nathenwallis5664]

Thanks for doing these videos, I know they have to suck to do on these super steels. I think you'll get the best performance with this particular steel by doing a low to medium grit edge on the Tsprof or KME. I personally prefer the Tsprof, but I got started on the KME, so I know you can get great results from both systems

[@dead7hed]

I quite like the Spyderco cbn bench stone, perhaps a bit more than the edges I get with DMT stones. I'd like to try some Poltava cbn stones in a fixed angle system. What cbn stones would you recommend?

Nice film 👍again. You won’t believe this, but mid-time KZbin plugged a Husk knive publicity 😅

Thanks to the outdoors55 KZbin channel I grabbed 2 $20 diamond stones and obviously practicing 10,000 hours to become competent + I can sharpen any steel. Absolutely fantastic ability but hard earned.

[@merlingeikie]

Sharpal diamond is his Otd55's favourite

[@The_RC_Guru]

@ his favorite maybe, but also he’s recommended the stones I got and they are fantastic.

[@Pablo668]

You didn't go to the pool party? C'mon Pete, you know the rule, suns out buns out!! Cool vid btw.

[@IwanVanMerhaege]

is paper of phonebook instead sheat paper better test material? is angle of stropping less than angle of sharpening with stone?

[@Wolf_K]

Phonebook paper and newsprint require a far cleaner and sharper edge to cut without tearing. An edge that can push cut printer paper may not push cut newsprint but an edge that _can_ push cut newsprint will easily do the same on printer paper. Printer paper is a rather low standard. A true high performance test media is Rizla green cigarette papers at 17gsm. If you can Pushcut against the grain on those then your edges are optimal for push cuts and shaving.

[@Wolf_K]

Hype really bothers me on a purely logical level. Why would it be hard to cut Rex121 or Maxamet when the Diamond abrasive is harder than the metals? Skelontized handles are stronger than solid steel ones…(Mike Stewart of BRKT actually said this in a video years ago). On skelonization “It actually makes it stronger” - Mike Stewart. “By this reasoning the strongest configuration would be no handle at all!” - Cliff Stamp’s response. 😂 More carbides equal better. 😂 lol

[@ryanjones7190]

This steel is not necessarily hard to sharpen but since there are more carbides the diamond abrasives dont cut as deep, making the grits feel finer and taking a lot longer to sharpen. Since you are taking more strokes it makes any mistakes more prominent and harder to remove. That being said ive got some of my best edges on rex 121

[@Wolf_K]

@ It only took me 14 minutes to regrind this exact model on Atoma 140 from stock bevel to ~6-8°ps and less than 1 minute to apex on DMT 600. Yes, I feel the difference but it’s still easily ground.

[@W3OY-RAY]

The knife wasn’t hard to sharpen at all. I did it using the Work Sharp Precision Adjust on a livestream. 320, 800, ceramic for deburr. All good. It’s a great knife.

[@ryanjones7190]

@Wolf_K yeah as long as you have diamond stones it's not that bad. Tbh I expected it to be worse but on low grit stones it's fine. I think the problem lies in when people only a 600 grit stone to regrind the edge. That makes it feel like you aren't taking material off. Also 6-8dps is wild that thing must cut like a laser beam.

[@Wolf_K]

@@ryanjones7190 ~6-8°ps is the secondary bevel, the apex (micro) is ~15°ps so it can still easily support the edge; but yeah, it cuts very well. I run almost all my knives low like this.
