Just as a point of properties : -strength is resistance to deformation (bending, prying, etc.), this is applying a force essentially very slow were the steel has time enough to deform (move) internally if necessary -toughness is resistance to fracture (impact), this is applying a force so fast that the steel can not deform fast enough to absorb energy and so it will crack if necessary (if over loaded)

Outstanding work, all I could think when the tip broke was Damn, that's some nice grain structure. I'd recommend testing corrosion resistance as well which should be easy enough. Temper 5 or so types of steal. Leave one set outside (because people forget stuff) put one set in a pair of jeans with a brine soaked ham (to represent edc) and leave one set in a bedside drawer (because you always need that knife until a better one comes along) walk away for a month and see what you come back too. Just my two cents. A great video boss!

Appreciate the effort you put into these, Alex. Glad you’re back.

Well done! You’ve gotten quite sophisticated in your knife builds compared to some of your earlier attempts. Very cool. Can’t wait to see the next step.

Doing great real world testing man. Congrats on raising the standards of your knife making skills and sharing your experience on the journey !

Basically one of the best knife maker channels there is. Period.. plus amazing information with cutting humour. Thanks Outdoors

Thank you for the time and effort! I love these real world comparisons that others don’t talk about

Thank you for taking the time to make and test various blade steel. Your information is a reliable resource.

Man, that's so cool you make your own knives.

Enter the land of diminishing returns... does the added cost equal the benefit? But you have already reached this conclusion Great Job Alex

@@greekveteran2715 It's simple, you're wrong. A Spyderco Delica isn't twice as good as an Ontario Rat with D2 steel. It might not be better than it at all. A Bark River Aurora II isn't three times as good as a Mora Garberg. I'd rather have the Aurora but no way it's three times as good. Now, the Benchmade Puukko comes in CPM-3V and costs more than the Garberg, but it probably is worth the extra money you pay. But the Puukko only costs $127.50 (versus $89.99 for the Garberg). The difference in price isn't huge, but the little bit extra you pay gets you superior steel and Benchmade's awesome warranty. As for CPM 3V being four times tougher than high carbon 1095--I very seriously doubt it. If your 1095 knife isn't robust enough for you, just make the blade a little thicker. The Becker BK2 is made out of 1095 Cro-Van, and that thing is a tank. Good luck trying to break it. The 1095 will definitely rust so you need to look after it. The1095 won't hold an edge long, but it's easy to sharpen.

Always great to watch. Thanks for inviting us to your continued education.

Great informative video! I’m subbing, one of best knife channels on KZread!

I've noticed 3V completely changes when cryo''ed in LN2 for 2 hours, Then hardened even more when Cryo'ed a second time over night, between tempers. It only gets worse on belts.

Very interesting brothee! I Truley enjoy watching your videos man. Keep doing what you do man

Great job on the heat treatment .

Another great video! Thanks for taking the time to make them!

Another great video my friend, still wish I could buy one of your knives. Congrats on 100k+ subscribers, enjoyable and informative video. I saw blackbeard project video do a place quench with compressed air was really interesting. Love the new shop and new equipment looks great.

Awesome video. My stress relief videos. Looking forward to the next one.

great job,appreciate all your hard work ,3v is awesome steel but then again so is 1080 and some of the others you've used

I’m a simple man. I see your videos I watch and hit like. Please keep the content coming! As for the steel if you’re making the knife for you I say make it out of the toughest and best material possible, extra work be damned!

thank you very much for this informative video. sound, video quality is at peak.

Great work ! I really like my TOOR darter with 3V a lot !

Very good video, I agree anything more would require a very well regulated testing protocol.

Men you sold me this knife concept like 4 vids ago, i want one!!!

Thanks for so much work and the results on your video's. Which is the best steel.

Thanks for all the effort! Tip test made me think it would have broken after first plunge-pry if it had scales you’d been able to grip it and rip it.

Re: edge retention. If you want to eliminate a *little* bit of the subjectivity of your cardboard cutting, go have a look at Pete’s data on the Cedric and Ada channel. He has a link to his spreadsheets in almost every video description now; just pick any of his recent videos and look in the description.

Try some Vanadis 4 Extra, even Ballbearing steel can get better on both edge retention and edge stability, compared to CPM 3V. It's not overrrated but there are way better performers in my experience out there (all things be equal of course, 'cause other atributes like heat treatment, bevel geometries, etc, are far more important.)

I really liked watching this series.

IMO the 3V still belongs to the category of "reasonable" super blade steels, not that crazy expensive with tons of Mo and V in it. Now the knife makers are simply promoting stuffs like M340 to get higher pricing on the product AND ignoring proper treatments to explore the potentials. Very educational video!

CPM-3V is my favorite steel for fixed blades.

I love Bark Rivers 3V I have 3 blades in it. You’re right it’s hard to work with & they have a company that water jets and grinds the primary bevel, then another company that does the HT so it’s easier for them because they just do the final grinding and apply handles (which is still a lot of work). Have you considered elmax, S35VN, M390, Cru-Wear is a great steel.

I doubt I'll ever nee to know all of this, (Can't afford the equipment for that metal) but thanks any way, enjoyed the video...your other videos have helped this old duffer much, Thanks...I don't know where you live but I love the woods in the background of the burn barrel.

i am impressed for this test

Great testing an how you made your own knife,I'm intrigued.

Good to see you again...I miss your content :)

What was the power bill for your oven on that build? Thanks for the education lesson...again. You truly love your craft.

Great test!

I liked the music for the tip breaking part

I like knifes because of their diversity or properties and uses. I rarely only have access to 1 knife that requires me to be super picky about that knife being perfect for every task. I do like balanced usefulness in a EDC knife, but life is full of compromises. Choose the ones that fit your needs.

Amazing work !!!

Very like your video, now very clear.

3 year old video but it just popped up for me. This video gave me a newfound respect for Mark Johnson of Vulcan Knives. He has built me two folders using Rex121 and a few more for other people. He had never even heard of the steel until I asked him if he was up to the challenge of building me a folder using it. He said it was quite a bit more difficult to work with than his usual 20cv but after watching this video I think he was downplaying how difficult it was, since Rex is a bit harder than 3v. If anyone is curious, both knives he made tested at 70 and 70.5hrc!

As to that tip breaking I think as you already know I'm sure that was more blade geometry than failing steel . At 76 now i think the whole super steel quest is necessary for some my self no . I have zero problems with sharping a blade every now and then .most everything I own is either 440 -c , 01 ,1095 ,and my favorite is 1056 . I am not a small knife guy and most knives tend to lean toward the Bowie style it's my thing and I love them all .Thanks for all your hard work in looking for that perfect material but for me it's cost I simply can't see paying hundreds for a knife it's just not necessary for me but for some it is the quest for the newest thing and good for them it's there fun in life so be it go for it . Happy trails stay safe in the shop. Get some cement board over the insulation paper behind your oven and above . Stay safe

Good job pal, man... that steel is no joke.

I like your work, thanks!

In regards to toughness, one thing to consider is long term use. Ed Schempp was one of the first makers for example to note that in Bladesports, a lot of steels can easily handle one competition, or even multiple but after awhile they will suffer catastrophic failure. This is why he preferred simple steels because they will outlast the life time of a user. I have seen knives last for days, even weeks of use and then suddenly just suffer gross failure, it is just an accumulation or growth of small micro-cracks. So even IF a steel can take a certain amount of use for low cycles (

@Star Gazer1212 Wood performance is a very different thing in many respects. It is mainly push cutting, and you want an edge which ideally wears very slow, no chipping surely. Try maybe W1, Super Blue, M2 or M4, make sure you get someone who hardens it in a sensible manner for wood cutting.

You doing great work👍

3V is a great steel, but the heat treat as you show is a pain. I used wet silicon carbide belts to grind it after HT so I didn't have to keep dunking it in water. Stuff is totally remarkable, but my heat treater used an air blast to quench. That plate quench is probably why the tip broke. The heat treat is why it is very expensive. It is a very shock resisting steel, that's why it's tougher, the very high vanadium content makes a lot of V carbide which is harder than tungsten carbide. Any of the high vanadium steels will hold an edge very well, better than any other steel just about.

Damn, that's a great test!

Nice work. Love your content...

These videos were awesome. I really want to get a great EDC fixed blade knife, but I'm so behind the times on what's out there. So I'm really glad to see your videos and I hope to see more, to try to figure out what I want in a fairly small EDC knife and how long I would have to save up for it. I may be disabled, but I'm not dead. Just low on money. Lol 🤣 I have love knives since I was 10 and learn the quickest way to lose interest in knives is to never have a good quality one, to see what a quality made knife feels like and what it can do. These new knives are just amazing. 😲

It would be interesting to learn what you need and how to make knives . I know you have covered some of this already but I don’t know if you put it in a new knife maker format

Great video! Do you take any custom orders for knives?

Wow, your test blade did much better than my Benchmade Leuku

you might try 8670. its affordable, easy to heat treat and extremely tough. It doesnt rust instantly like that one alloy you had either. check out the baton test on the 8670 chef knife on Alpha Knife Supply.

Great demo of 3V. Doing the grind after the heat treat is more common? Or do knife makers do most grinds before heat treating the steel?

Thank you!

Tough steel. Good video. Thank you.

Great video buddy

I have the SRK in 3v and I'm now resisting the urge to put some abuse to it. Good video, and I think the answer is the cost in time and effort depends on the efficiency in manufacturing. Heat treating 1 blade at a time vs Heat treating 100 blades at a time or having a constant revolving 1 blade on one blade off to the next step assembly type production makes it much more plausible but again. That's not the small or custom knife makers forte until they are a little more advanced and established and even then. I'd say it's a flagship metal although i'm curious how polished the steel will get as my SRK is fairly dull and more of a grey color than it is silver.

Excellent review, thank you for your time doing it. One question, what are the staining and rusting characteristics of this steel? I’ve been using New Jersey Steel Baron‘s nitro V steel and wonder how it would stack up in a test like you’ve done. 🤔

Are you by chance taking pre release orders for the final design , if so please let me know I would like to be in the first group to get your first production run.

How do feel about S30V? I bought a Benchmade Bushcrafter awhile ago but had to change the grind it's laughable out of box. They really like putting folder grinds on fixed blades .... I was not happy with the stock blade. Even the handle was off a bit but I just fixed it all and now it's a great knife amd holds up well. . That said I think a 1095 version would be just fine to me .. I just don't really care anymore . I'd rather just have a good 1095 that sharpens without diamond stones.
