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

[@toolthoughts]

World's best steel, unless you want toughness, very fine edges, machinability, chemical resistance, low toxicity etc.

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

[@3xK_Dziubas]

Mine has been with me for two days, but I'm already madly in love with it. The current Spyderco with K390 rests in a drawer. Spyderco - you are the champion!

[@thechugdude]

15V did 2000 cuts with your edge. Rex 121 did 2000 cuts with a factory edge. It's going to be fun to see what it can do with your edge!.

[@Aerzon1v1]

Now I'm excited....

[@FT4Freedom]

My money is on greater than 2500 cuts.

[@LoreTunderin]

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

[@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!

[@Spthomas47]

Agreed. When mine came in it was pretty sharp. Not ssSCREAMING sharp, but very sharp. I also realized I had no stones that would sharpen a steel 70+hrc lol (since remedied as I've wanted some diamond "stones" anyway). I do have diamond infused stropping solutions, so I put a freaking bangin mirror polish on the edge. Other than wiping it off, the edge/mirror hasn't budged even a bit in the over a month I've been carrying it. Granted, I've only cut pipe insulation, cardboard, foam, paper and the like, but still. ✌🏼🤘🏼

[@monstersbox]

Jesus - the difference in sharpening maxanet vs rex 121 is an exercise is masochism. I've been slowly working on the 121 when I want to feel like I've made all the wrong choices in life over the past couple of weeks and it's just not worth it when comparing it to maxanet. I consider maxanet a pleasure. Rex 121 is finally the point where I decided there is in fact a steel I hate to sharpen.

[@Mr.9x19mm]

What a performance. Wow!

[@merrickx]

This reminds me of my old, very used Spyderco Maxamet blade. It never stopped cutting paper, even when it got some tiny chips in it - it only became toothier and wanted to bite into the paper more, but not stop slicing it. Even the small chips acted more like serrations.

[@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.

[@narkfly]

I think the Sage 5 is one of the Spyderco models that benefits the most from aftermarket scales. It's pretty underappreciated, so there are hardly any videos showing off a re-scaled Sage 5.

[@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.

[@Itrieditathome889]

Man I've been waiting for this one! I reprofiled mine to 14° per side and it was hands down the worst sharpening experience ever. It just takes so long to even make minor progress on the edge.

[@GratefulLoC]

This was the first Spyderco that I actually got the day of release and it really is wild. Lucky it came in a Sage because if it were a Golden/Seki City model I wouldn't be looking forward to having to reprofile this thing (on that note, wish there were more evergreen/non-collab models made in Taiwan in general). Great vid man, always excited when I see one of yours pop up in my sub feed.

[@BjCmeadows]

Thank you for sacrificing your joints and tendons for our entertainment and enlightenment

[@Wolf_K]

The finish on it is like a # 36 - # 60 that’s been heavily buffed. No surprises why. 😂 I got one recently…it took 14 minutes to reprofile on Atoma # 140 from stock to ~6°ps and 1 minute to apex a ~ 15°ps micro. Side note, while people have been showing Rex121 scratching/cutting glass as a party trick , Maxamet also does the same. I cut up a coffee jar to see. It sharpens easy, no real difference to Maxamet. Reprofile takes a little longer but still only 14 minutes. Edit: another thing about rex121, it takes a really nice mirror polish. _Really_ nice.

[@snowhusk]

Technically speaking anything above certain HRC would scratch glass. I've seen slightly different numbers, but >65hrc seems to be threshold for being able to scratch glass🤔

[@Wolf_K]

@ Yeah, it also depends on the hardness of the glass as it varies. I just thought it funny that I was seeing advocates of duper steels cutting glass with their Rex121 blades as some sort of “high performance” test, as like you said, many blades will do it if hard enough.

[@PuReBlOoD3478]

[@charlescollier7217]

Thanks for this Pete. Santa brought me one of these Rex 121 Sages for Christmas. Given this result, I'm tempted to carry it every day and see if I need to sharpen it before NEXT Christmas.

[@somedude....]

Something I've always appreciated judging edge retention and tracking degradation through cut tests such as these is the sound of the paper cut. We don't get to see the fine details of the paper getting cut, but the difference in sound is clear as day as we all know the sound of a4 paper being cut by varying degrees of sharpness.

[@williamthompson9262]

I just sharpened it for the first time on the KME. It wasn’t bad it just took a while.

[@Halluzinate]

It's such an amazing knife & steel that I'm actually considering buying the LW after already owning the G10 version. It's insane how great Rex-121 on a Sage 5 is because the tip isn't super brittle like a clip point PM2. I would also love a Rex-121 Manix 2 but a Sage 5 is what I call a "better Para 3". Sorry if that upsets some folks lol I just like it better.

[@cal1776]

Thank you

[@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!

[@knivesandstuff]
