    Old fashioned distilled vinegar will work to...just do it over and gain and rub off the reactive crud. A gallon of vinegar is cheap

    I'd like to add some notes that are specifically for the a Hattori KD re-etch job....


    1. The bolsters on these particular knives are nickel silver (AKA silver looking brass) and being such will easily turn nasty if the etchant touches them AND will bleed red streaks down onto the blade. Be sure to mask off these bolsters beforehand and do your best to stay away from them with the etchant.

    And BTW, masking off bolsters isn't a bad idea for any knife being etched.

    If you do happen to etch a bolster you're going to have to sand it back to the desired finish.



    2. The maker's mark (red stamp) will disappear. To what degree this happens depends on how long the blade is etched, how well the mark was applied, and dumb luck. I can say for sure that the more time spent in the acid will greatly increase the likelihood that this mark will dissolve away.

    I think it'd be great to coat this area with a resist like clear nail polish pre-etch but how exactly to do that without making it look like crap is something I can't help with, this is just an idea is all.

    I was thinking the same thing! When I'm learning, I'm not making any money.

    I wiped off the red mark of my Hattori FH with acetone, could only imagine what ferric chloride would be capable of.

    This worked great to re-etch my yoshihiro vg-10 damascus before I gift it to my dad. Thanks for the tutorial!
