    acid etching carbon blades

    decided to etch my knives other day, had nice results.
    hard part was finding a container large enough to fit nearly 11" gyuto, used a tall plastic cereal saver box.
    mostly filled with warm water, then 250mL of ferric chloride. so a very diluted solution.

    3 times at 1 minute intervals, scrubbed with 0000 steel wool in between each dunk and cleaned with soap after final soak.

    left to right:
    watanabe 270, shigefusa 240, tanaka 210, tanaka 105





    my reason for doing this was not to make it look cool, but in hopes to make it less reactive and offer some sort of protection. the looking badass is just a bonus. after using them they stink less and aren't leaking all sorts of marks on the blade as crazy as before. perhaps forcing a mustard patina OVER this acid etch would serve to be even more robust.

    How's that Watanabe Pro working out for you?

    Those look really cool! And reducing reactivity is good, too.

    Any idea of about how much water you used? Some of us might want to try, and having a better idea of the ratio would help. Thanks.

    Those look great -

    I saw a great setup watching a Fowler vid on youtube. He used a length of PVC with a cap on the bottom and a screw cap on the top. That way he could store his etching solution and use it at will. It's a stiff setup so you can rig up a dip for already handled knives without worry of a complete dunk.

    re: wat pro - working quite well, it falls through things (even sticks into the board) and the best food release i've encountered. still getting used to the profile and massiveness of it all. get some mild accordioning and wedging, but that will settle once i get accustomed to using it.

    ratio is just about 10 parts water 1 part acid as the container was 2.5liters and i used .25liter acid.
    i forgot to mention i also heated up the blade prior to the first dunk by running it under hot running water for 1 minute (rotating the face every 10 sec). whether or not that did anything i have no idea, i just remembered someone saying that if you heat up the blade it helps get a better patina so i tried it.

    Nice work Panda can't wait to do this on some knives. By chance do you have before pics so we can see the contrast?
