    Need some thoughts on etching stainless (AEB-L) I I put this one in the ferric yesterday for maybe 30min, very week mix maybe 10 parts water 1 part ferric. Before etch I wiped down with parts cleaner, then asetone, then denatured alcohol.

    I was looking for just a dark consistent finish but I got patterns, I think I will keep the pattern now because it’s interesting but any thoughts on what’s going on? Do I need a stronger mix to etch stainless?5rbudpvlmrbhqxvp.jpeg

    Not sure of any root cause, But I think it looks interesting.

    That is a super interesting pattern... maybe the AEB-L isn't "pure"/wasn't mixed completely? How did it harden? Have you had a different result out of this same bar/batch? Being a chef's knife I wouldn't bother 'testing it to destruction, but I might make a coupon of the same bar/batch and HT it the same way you did this knife. Then clean and etch it the same way in the same bath and see what the results are.

    I do HT with Peters heat treating so that is out of my control, but about as reliable as they come. I have completed and tested other blades of this batch without any issues but not done an etch on the others.
    I have always had strange results etching aeb-l with parts of the blade turning black and other parts remaining untouched. I do think my week ferric mix may have something to do with it. I did a quick test with un-mixed ferric this morning and it started to etch evenly right away.
    The knife is now glued up and will be finished soon, I will see if anything strange happens in testing but so far the steel seems normal.
    Now I am just hoping that I can duplicate this look in the future.

    Duplicating a happy accident is had to do! I would never use full strength ferric...it actually works better when diluted a bit. at least 2:1. Have you tried the coffee etch?! just a thought. Let us see when completed! I'm excited to see the end result! I actually am hoping my AEB-L etches similarly! I think it looks cool! Kinda of a stainless damascus!

    Congrats... you created Mono-mascus. Looks excellent. I wouldn't change anything.

    As far as consistent etching, I use closer to a 3-1 mixture and I use a makeup remover pad. Dip for 30 seconds, scrub with the pad, repeat three times then let it soak. Seems to give me the most consistent and clean full etch.

    Looks like alloy banding.
