    I have not been able to find all that much info on this steel, other than its composition seems to be very similar to that of vg10. I am looking to purchase a stainless chef knife and many of the options have aus10a rather than the vg10 i am used to.

    What is your experience with this steel, and have would you say it performs in comparison to stainless steels like 154cm/vg10.? I have a few knives in AUS8 which are not bad by any means but the edge retention is rather lacking.

    AUS 10 (10A): A high-carbon (1.1%) stainless steel with greater toughness but less corrosion resistance than 440C thanks to the addition of vanadium and the subtraction of chromium from the alloy.

    On Japany.com they consider it slightly tougher than 440C difficult to sharpen does not take a great edge and has good retention.

    From the reviews I found people seem all positive about the steel. I have no experience with it but it is certainly a good Japanese product.

    you can poke at this tread if you want https://www.bladeforums.com/threads/aus-10-vs-vg10.668017/

    AUS-10 is similar to VG-10 in that it is a ~1.0%C steel but with lower chromium than 440C. The lower chromium means lower corrosion resistance and wear resistance but higher toughness, hardness, and edge stability than 440C. If heat treated well it should be a fine choice.

    Before VG10, Aus10 and ATS34 were the top Japanese steels. Some claimed Aus10 was better than Ats34. Spyderco had a Native in it for years, marketing it as a premium steel. I think Cold Steel used it as ther premium steel in a few knives. I'd trust it.

    I have a knife with an AUS10 blade. It's edge retention is similar to that of VG10 or 154CM, assuming all are hardened to the same Rockwell and assuming the edge profiles match up. A definite step above 440C and AUS8, a definite step below S30V.

    My wife's job is basically a prep cook and after trying the much recommended Victorinox Vibrox handled chef knife, and we were both greatly let down by the blade steel. She would bring it home for me to resharpen what seemed like every other day. I tried a few different sharpening techniques and edge angles, but it just wasn't great. I searched for another chef knife that would fit in our budget and ended up finding a Wallop brand japanese knife for about half off retail. The blade steel is AUS10. We have been incredibly impressed! I sharpen once a week, and even then it is just a minor touch up. I just ordered another knife from the same company, with the same steel, again for about half off of retail. So this is only my experience with one knife, from one maker, but AUS10 has been extremely good to me! [​IMG]

    Nice looking knife. Is that a damascus pattern?

    I actually ended up purchasing a Shun Kanso 8" which comes in aus10. Not here yet but very excited to see how it performs.

    That's a nice looking knife! Let us know how you like it.

    My other Wallop knife came in and it is a beast! 8.5" chef in AUS10-

    Dr. Rez, I am Dr. Mark. Depending on the cash you desire to lay out, AUS10A seems to be about average steel for an EDC. I am not a metallurgist, not any kind of expert in the field, but merely a long term enthusiast with an extensive collection. Depending on your purpose, the frequency of use, and the heat treatment process, it should serve you well. I find AUS10a steel in manufactured knives. If you are a collector, it should be fine. I prefer mid to high-end knives since I am in the field and require top performance so it would really not benefit me. I have a 6" Cold Steel Rajah folder with AUS10a, and for a $100.00 knife, it is a fine addition to my Cold Steel collection. Light to medium tasks should work well for you.

    What field are you in (Dr Mark) and what do you do that requires top performance from your knives? John

    It always puzzles me that here on BF where folks are so knowledgeable (and sometimes even apparently obsessed over..lol) various steel types that the erroneous terms Aus6A, Aus8A, Aus10A are still used.
    The correct term is Aus6 or 6A, Aus8 or 8A, or Aus10 or 10A.
    According to the maker of these steels, Aichi Steel Corp, they are all annealed. In Japan they are called A6, A8, A10 respectively.
    Decades ago Cold Steel started the "Aus8A" misnomer, either unknowingly by error, or deliberately as it sounded "cooler".
    Of course making up all sorts of names for steels is far from uncommon.
