    They’re both so good. They both have minuscule trade offs.

    But minuscule trade offs is what we enjoy banging the table about :( :cool: :)

    This could be a banner for any enthusiast forum, about any topic. It’s so true.

    I agree about use of extreme caution when basing a steel's quality strictly of an edge retention test. Across the gamut of performance items (outside of steel) 'the best' usually is the most well rounded in all potential assessments versus zeroing in on a single category - like edge retention. Market entrants typically like to call out a single spec whereas the market leader who has years of testing and budget to back it up and make improvements usually migrates to all around performance. It is much more difficult to be very good to excellent across 10+ parameters than being able to claim to be the best in a single parameter. I assume different blade grinds also could favor the makeup of one steel over another, never mind brand to brand. In summary I don't think there can be a straight forward answer.

    I have owned knives in both steels, and both get the job done. From all of the research I have done, S35VN is tougher and possibly easier to sharpen, but CPM20CV excels in the other areas.

    I do believe that the 20cv steel must cost the makers more than s35v, based on the prices of knives with each steel. 20 cv ,like m390, seems to have a nice balance of high levels of edge retention, resistance to corrosion , and toughness without having the best in any of these categories. Great for a high quality folder.
    And to the reason for the reply to your last sentence, my last acquisition was a great bargain with 20cv steel. To find this exclusive, Google Buck Maverick.
    Sturdy blade. Good hollow ground for slicing. And Bos heat treatment. Wait until you see the price. I ve been carrying mine a few weeks and am very pleased.

    I see that it's a special run of the Vantage. Interesting. That particular knife is not really to my taste anymore, but I'm glad that it exists. I had not had any idea. Insane price.

    I can’t tell the difference in terms of ease of sharpening between 20cv, s30v, 35vn, and even 440c as done by bos ht protocols. I’ve never counted the number of passes, but to me they all feel roughly the same.

    Touch up, sure. Very comparable.

    I haven’t reset an edge in 20CV, yet. I imagine that would be where the difference is most felt.

    I would think so, 20cv having significantly more carbon, chromium and vanadium(same as s30v but less than s35vn) that it would be the hardest one to resharpen of all. But I can’t feel the difference, except that ime the s30v seems to get more miniscule chipping at the edge from use.

    I’ve seen a 20CV folder get baton’d through kiln dried hickory. That’s much harder than Oak...

    Didn’t busse make 9” bladed knives from elmax—which another member stated above was pretty close to 20cv—once upon a time?

    20CV is a better steel that will hold its edge much longer.

    As a buyer of knives, my rule of law would be, if it is under 4.5 inch blade and you can get it in M390, 20CV or 204P do it. If it's between 4.5 and 7.5 get the S35VN. If it's between 7.5 and 13 get 3V. If it's between 13 and 24 get CruWear.

    I am sure 20CV is more expensive to work as a manufacturer, over and above S35VN.

    I do believe that most tests/expert opinions will place 20CV above S35, unequivocally, all day. However, I'm not going to research/cite anything for you, so take that for what's worth.

    In my experience, 20CV is the superior steel. It offers the best corrosion resistance I have ever experienced save for rust proof steels such as H1, etc. I wouldn't hesitate to own either, and I do, however I do go out of my way to purchase M390/204P/20CV these days.
