    I’ve been having “blotchy” etching results. Not sure why I can’t find an answer anywhere.

    Here’s what I’ve been doing:

    o1 tool steel
    cleaning area with laquer thinner then alcohol
    Using tape or nail polish or vinyl stickers
    Salt water solution
    Felt or cotton or qtips
    12v battery charger

    My problem is I’m getting blotchy areas where there is a clear distinction between how the etching worked in one area vs another. I have no idea why this is happening. Any help would be really appreciated.

    Below is one of my first knives I used as a guinea pig around the shop but the results of my etching are similar to what you can distinctly see here.

    My main etching going forward will be done with vinyl stickers I’m having made up.

    Well apparently I’m having trouble posting a pic. At least I can’t see it on my end either way I tried to post it.

    Little tech support lol?

    Hi,
    What photo hosting service are you using? Imgur, Flikr, Google etc.

    I don’t use any of those. My pics are on my phone. Can I assume from your reply that there is no way for me to post pics here unless I put all my pics “on the cloud”?

    Yes, the pics you want to show will have to be on the web somewhere.

    All the blotchy’ness I have ever gotten with etching has been because of not putting on gloves. Acid, sweat or general ‘shop hands and shop environment,’ totally F’up etching lol!

    I glove up first and foremost.

    I degrease with WD40 degreaser (any degreaser will do) this is what takes off contaminants, acetone and thinner will clean, but they don’t remove surface crap like oils, grease, you’d be surprised what settles on a knife surface as it goes through a shop. Residue from grinding I am sure you can imagine dirty up your knife, like the grit and the bonding agents on belts. Also maybe like me you also do some final grinding and spray WD40 or another of its kind on the belts, or maybe you use it while hand sanding. That all gets left on the surface.

    Acetone then...works great as a secondary cleaner after degreasing.

    I apply my vinyl stencil. I etch with my Personalizer Plus only the highest setting.

    Below is the Welsh Dragon I put on my own personal Kitchen Cutter, I never did put a handle on it, been testing the edge in everyday use :D
