Never saw a steel that was this hard to sharpen, unbelievable, thx for the vid.

[@thedrmurchindise]

Maxament,10v, CPM rex121, all very difficult to sharpen, even on diamond.

[@RadDadisRad]

Cpm-20cv/M390 isn’t easy either

[@williammccaslin8527]

Yep it figures I would be behind the curve on steels, but I'm a "OLD SCHOOL " carbon steel fanboy

[@99gmcsierralm74]

Wait so if it’s so hard to sharpen does that mean that is a hard steel and it will take a beating before it needs to be sharpened again???

[@DutchBushcraftKnives]

@@RadDadisRad compared to this its still a walk in the park haha but you're right

[@emeraldplatypus9870]

Plz get some of the Sandrin tungsten carbide fix blades, have fun sharpening those, that might get your 10/10 for edge retention...

[@alexanderbertallo1995]

You should contact KKnives Switzerland here on youtube. He runs Rex121 harder than 72 HRC... much harder!

[@mirnogo]

Yes far beyond bushcraft capabilities, I have ordered a k390 from dulo and really can't wait to get it outdoors. Cheers for putting me on to them!

[@TheJazzyjake1234]

How do you like your knife from him I'm looking at buying one

[@justicesword1549]

I guess you need a Wicked Edge Pro to sharpen that steel with the right results ! Amazing steel and Dulo has also brought the S390 steelwhich is the equivalent to REX 121 made by Sandvik.

[@codyjarvis115]

Always enjoy watching you guys! You've got my dream job! Keep it up!

Love my Maxamet PM3 😋. No sharpening nightmare with diamond stone. But never let it dull as a butter knife, it would be impossible to bring it back to life 😅

[@pecopecof8074]

It's not impossible, just half of your life will be on the wet stones or diamond stones...

[@milesrobertson6882]

That music got me pumped up- I felt like feathersticking the whole world listening to the music flow while you batoned.

[@bushcraftingmuslim]

Great video, very informative and entertaining. I'd maybe try rex121 for an EDC knife that was for gentle use and I wanted to always have it sharp, but honestly it looks not worth it even for that.

[@LutiqueDota2]

Молодцы ребята, нравится ваш контент, nice bro

[@GOxHAM]

Wow, can't believe diamond stones weren't abrasive enough. 72 HRC is INSANE!!! Maybe try "the beast" kme stone on it? It's a 50 grit diamond stone. It's small since it's meant to be used for KMEs sharpening system, but you could still use it as a small hand sharpening stone.

[@andyy361]

Late reply, but you can't sharpen steel this hard at such a low grit. It will just create micro chips at the edge. A 400-600 grit diamond would be best for this steel.

[@donaldfucetola6026]

Oooo, didn't think a knife would catch my eye after the trc souuthpole but...i gotta have one.

[@jakehu6671]

You don't profile the knife with waterstones, waterstones get profiled by the knife.

[@Owieczkin]

Sounds like some soviet knife

[@mikaelrabb1876]

They probably design the knife to be able to flatten the stones!

That must've taken hours to sharpen, when I bought my BK-2 it took me at least 2 or 3 hours to remove most of the black coating that it comes with and to also give a nice convex grind

[@ryewaldman2214]

I have a Creely Mako in Rex121 and I've been able to get it (keep it?) screaming sharp via 1) DMT diamond plates Coarse, Fine, Extra Fine + spyderco ultrafine ceramic + stropping with diamond paste and 2) the Gritomatic sourced Venev diamond water stones 240, 400, 800, 1200 + stropping with diamond paste. These are the types of abrasives to use for the high-carbide powder metal steels. I do the progression to get a nice polish on the edge but it isn't required. Once can have very sharp supersteel knife edges, shaving sharp, with a DMT double sided plate: course/fine + a leather strop with some 5 micron diamond paste. Not a very expensive sharpening set, and can be sourced on amazon or your favorite knife distributor. Save the japanese water stones and anything else based on Aluminum Oxide for the kitchen knives, the high carbon steels, and the basic (e.g., vg 10, 154cm, 440) stainless steels.

[@metalronin]

They sharpened it with Naniwa Diamond stones as far as I can tell. These are resin bonded diamond stones like the Venev stones you mentioned.

[@HPAcustomriflesandcerakote]

I have sharpened rex121, most definitely hard but just like maxamet and s90v diamond stones must be used. I use to use DMT diamond plates but they do not last so i upgrades to Naniwa Diamond resin bond stones since i am a Naniwa fan of their water stones owning all the Chosera stones and several other naniwa stones. Got to br

[@-trmxzer0-235]

I've got a custom fixed blade in Cpm Rex 121 at 71 hrc and I can't believe you batoned with it that blade also try using Venev's OCB stones they will save your arms

[@ilzephyrli]

Have you tried the Brother F005 bushcraft knife? Looks like an amazing deal.

[@elementonyoutube6556]

This was good and short. ...Too short. You guys mention your favorite steels all the time BUT: Have you guys considered making an opinionated video on the Balance between edge retention and The HRC factor? 🤔 What happens when survival goes for much longer than a week and living in the wilderness becomes a way of life? Cutting rope (assuming you can make rope) and chopping wood would be constant. How would you sharpen your knife? With a flat rock or brick? How does your Favorite Steels play into a hardcore challenge?? I remember these topics being touched on in previous videos but it would be great to see all this in 1 longterm setup.

Hello Mikkie and Marteen, Guys look, that's why regular hardness doesn't go that high since it's much better to bend an edge, not break one!!!😖😱😢🧐 Unless that Manufacturer will re-profile the edge at no cost, that's an expensive mistake! Even I'd rather have to constantly sharpen a knife then chance to break one, don't believe I'd want one. Thanks for your vids and this wonderful opportunity! I'll not hold my breath to win as I'd just pass out for nothing!😖 I'll keep my 🙏🏻🤞🤞 in Hope's of being chosen. Take care, "God Bless", sincerely, Randy. 👍👍🙏🏻😇👊

[@nathenwallis5664]

I'd try again with diamond plates only, and diamond emulsions for stropping

How did the maker do it? Is the steel more normal before heat treatment? But final polishing and sharpening? Would love to hear the makers comments.

[@jamesbarisitz4794]

Glue a diamond sanding stone to a large Sawzall blade with epoxy. Clamp the Sawzall to a work bench. Adjust the speed to suit the stock removal. A stream of water from a container directed to area with a small hose will keep the heat low as you reprofile the chip out- faster than a human should be able to do.👍

It as AUS 8, which I have not had problems with before, thing maybe a bad heat treat or something. Would love some ones opinion on this blade

[@alexandernanov3970]

The knife in the video is made by Dulo Knives. I guess you can order the same knife (or other knife by your preference) with that steel from them.

[@alastairwhigham9283]

The only thing remotely close to this i have sharpened is rex45 and that required DMT stones but its so fragile! As soon as you build up a burr/wire edge it just snaps off on the stone in long pieces that look about as thick as a hair its holds an amazing edge but it takes a very light hand and lots of stropping to get a fine edge without the edge crumbling off ! The knife i had was a spyderco pm2 rex45 and it was just too thin behind the edge to utilise this steel in any medium to hard use (for a folding knife) without getting chips or edge peeling even just sharpening a pencil etc (i kept the bevel pretty much at the factory geometry)

[@robertschuenemann7390]

With a Rockwell hardness of 70-72 it's no wonder this thing retains its edge like that! I haven't decided if I want one. Probably. It's the hardest tool steel I've seen. My Nieto Chaman has a hardness of 60-62, which I thought was hard, and the NOC Knife has a hardness rating of 62-64, but this thing is from another PLANET! It's the vanadium content that gives these their extreme hardness. Okay, I want one!

[@socmonki]

It's probably the Tungsten.
