S90V is the queen of folder steels. This controversy in the comments is why cruwear is actually the King though. You can get a crazy keen edge with a smooth piece of quartz while being a fine grain powder metallurgy steel in a survival situation. It’s a low alloy steel like 3V and 4V at only 14% alloy to 86% Iron. While S30V and its evolutions are roughly 23% carbide formers and grain refiner alloying elements. 20CV and its sisters are 28%, and S110V and Maxamet are 35% alloy. This explains the chippyness as it goes higher. Even magnacut is 21% impure, yet it’s very tough. That 2% niobium was interesting when I first saw it because I always assumed the 3% Niobium in S110V was very unique are required to give it a usable amount of toughness. Tungsten seems to help retain toughness the most though with K390 and especially Rex 45 being high alloy AND tough. Cruwear however is also rather stainless to the point where it really matters at the apex. It’s similar to Magnacut in having an element ratio intended for minimal Chromium carbides. With 25% more purity in comparison. This is the reason people gravitate towards Cruwear despite looking mediocre on paper. It literally has a potential to just be sharper than most other powder steels with less chunky big carbides at the apex. This also why many still love 1095.

s90v has been here all along - for some time now. It gained a reputation for being hard to sharpen (likely before diamond abrasives were widely available for a decent price). Shiny new steels came along and overshadowed it's stellar properties. Knife destruction videos became popular and toughness became super important - why? - who knows - most EDC uses don't come close to approaching the "lower" toughness of s90v. Now it's becoming discovered again and I'm glad. It's a fantastic EDC steel - even for non-knife folks as it will simply stay sharp forever for them.

We're in such a special time when it comes to knife steels. I think that steels like S90V and S45VN just didn't get enough traction in the luxury knife market as M390, Magnacut, or even CPM-20CV did/do. A lot of people were still hyper focused on figuring out whether they should want S30VN or S35VN, when these other steels were being waived in front of them. On the business side if you just bought a ton of M390, because you got a good deal on it, that's what you're using. Now it's just a matter of sorting knife makers by their heat treatments for specific steels. It's to the point where I'm all in if one guy is working with a steel they do amazing work with, but I maybe don't want to be an early adopter if they're using something like Magnacut for the first time.

I almost bought a Maximet Manix 2 LW two weeks ago, but decided against it. I don't demand a lot of toughness out of my knives and I only tend to use them for cutting tasks, but the thought of getting an expensive knife with such low toughness was too much for me. I went with the S110V specifically to get just a bit more toughness back while still having really good edge retention and better corrosion resistance. Being slightly cheaper was a nice bonus. If there was one available in S90V, I would have chosen that as it seems to be superior to S110V in just about every metric.

S90V is not just a first class EDC steel... It is a great bushcraft steel in a stout (4 mm +) "fixed Blade" Knife. It is Fine-grained, is tougher than 440-C & as tough as D2 & M2 steels with better edge apex stability and compressive strength (60-61 HRC). It handles a 16-17 degrees / Side "angle of attack" Edge, without chipping... & I do baton with it... (precisely & judiciously)

That being said, i haven't sharpened it yet, and i worry about the ease of sharpening. I've got experience with V10, s30v, m390 and magnacut in sharpening. Thusfar magnacut was one of my favorites to sharpen and easier to remove the burr. I'm going to try with S90V but im also curious like you said, why this isn't more marketed

I think one of the things holding back s90v is misconceptions. It has become the norm for people to think a knife is dull if it doesn't shave cleanly. noting could be further from the truth. It only counts if you use your knife for actual shaving day in and day out. Impressing your friends is nothing more than a snake oil salesman parlor trick. A blade that shaves cleanly very rarely can cut anything that is actually tough as most things we have to use a knife for daily are. S90v's course vanadium carbides do not like to shave well and if it does, not for long. What it does do is obtain a very aggressive edge able to laser thru very tough materials and do it over and over again for a tremendously long time. It isn't for impressing people for show. It is for actual hard work and excels At IT! For impressing your friends, stick to a steel designed originally for making razor blades such as 14c28n. Shaving is what it is made for. It just won't cut anything real world for long. As far as not doing well in abuse test, I'll tell you the same thing that R.W. loveless or Jim Merritt would. A man who abuses his fine tools doesn't deserve fine tools. You need a pry bar, use a pry bar, need an ax, they make those. Screw driver, they make those too. A craftsman uses the proper tool for the job. A fool doesn't care. KnifeMaker/Retired after over 47+ years in the Craft in association with the Loveless Shop

Magnacut and S90v are just different. S90v has more than double the vanadium. Significantly more wear resistance. There is no other option for a stainless steel with top tier edge retention and reasonable toughness. There is a cost - magnacut is more stainless, tougher and easier to sharpen. It just depends on what you want. I like magnacut when it's treated hard. But if someone wants to sell e a $300 magnacut knife at 60-62 HRC, why not just get a $50 14c28n knife for more toughness, same corrosion resistance and little less edge retention.

The only S90V knife I have is a SBD Apex... So I'm kind of hesitant to put it to work. I also found it has a dull spot near the heel so that makes me even more nervous about sharpening it before using it. I suppose I could go for one of the Pyrites with S90V as a way to use the steel at a lower cost but still... it eludes me at the moment.

Someone asked me, how do you ever sharpen it??? My answer is to never let it get dull. Many manufacturers will use a belt sharpener which will heat the edge making it brittle. After you sharpen on a whetstone by hand it won't chip as bad.

Exactly. Factory edges comes "burned". I usually never ever create burr when sharpening. One stroke one side, one stroke other side and repeat. Doing that way even my maxamet never had issues.

Congrats! That's going to be a great carry! For stropping s90v this is what I recommend 1. Use diamond compound (I prefer gunny juice and I'd suggest no lower than 1 micron) 2. Strop in the same direction the edge striations are going..if sharpened at an angle stropping at that angle if the striations are factory vertical than strop straight back and forth 3. Don't apply pressure at the edge, this will cause an indent in your strop and roll your edge.

@@Rollshambo I find that the high vanadium content enjoys a course edge such as 325 to 500 cbn or diamond and strop very lightly only one or two passes with 3/7 or slightly courser grit in diamond or cbn paste.

@Rollshambo 9 ай бұрын

That's a great question..magnacut with sub 63 hrc is essentially going to perform like d2 with better corrosion resistance..at 63-64 however it spikes that edge retention dramatically without losing a ton of toughness and at that point I'd say it would be better as an all around steel than s90v...However its not these individual scenarios that I like to judge steels on, it's based on what we can expect on a consistent basis..and because people aren't as informed as they could be I have a hard time reccomending magnacut knowing that I could just be encouraging people to buy trumped up D2 at a premium pricetag when they could have gotten s90v and even at 59 hrc experience super steel level wear resistance

It is likely that the scarcity of CPM S90V is due to the difficulty in machining it. Knife makers prefer a steel that is easier to work with as a business decision, to pump out more knives. Extremely wear resistant steels require specialized materials for sharpening (more expense), and more time required.

S90V is less popular because its really hard to manufacture and its actully not as tuff as you keep making it out to be.

@Rollshambo 5 ай бұрын

It's actually been gaining in popularity recently..it's more likely that up until now it's been used less because manufacturers buy these steels in huge bulk quantities and aim for what they think will be more popular, then they have to use up all that steel all while watching the market shift and sometimes that can take years...the issue with abusing knives for testing is that you prove a lot about that specific knife and only a little about the steel since at that point I'd be testing the heat treat of that specific piece and the geometry/build quality of that specific piece while testing a different knife made of the same steel could yield vastly different results...so at that point your left just testing steel blanks which is what Larrin did..but most non metallurgists don't have the equipment and space to accurately do that..if you do I'd love to drop by and do some testing

S90V is a soft steel. Abrasion resistance catra numbers should not be confused with edge retention. For cardboard and foam, OK, but for general use, hardness is as important. And toughness also dictates how thin of a geometry you can have along with hardness. So for edge stability, I think that around 64 Magnacut and K390 are kings. Also S90V is not that tough, I think it should not be use in thinner knives like bugout or pyrite. I any way, cheap Chinese companies know how to treat around 60, so we can have nice S90V knives for good prices. (I have the Kubey Dandy, a prybar sharpened at 25dps like this steel should be. It's of no use, too thick, but it will certainly no chip)

I do believe the highest rating for that category on larrin thomases list is 10..that said its the same toughness rating as m390 which hasn't been reported to have issues breaking and shattering like maxamet or Rex 121 who both have lower toughness ratings.. also when considering how sturdy a steel is going to be things like blade stock thickness, edge geometry and blade shape will all play an important roll as well.. the screenshots of the list were based off high edge retention super steels, the common tradeoff for high edge retention is low toughness, that said if it's toughness you seek 14c and lc200n as well as 3v would all be excellent choices
