How-To: Simple Electro-Etching for Knife Blades

A bit of nail polish, a container of salt water, a 9V battery, a Q-tip, and some alligator leads. That’s pretty much it. Easy, inexpensive electro-etching process from Instructables user lasersage appears to give impressive results.

    A suggestion for the blog editors: please add a bit more content to posts like this (or make it much clearer in the photographs) so I don’t have to click through to find out what electro-etching is, and why I might want to do it.

    A suggestion for the blog editors: add just a little more content to posts like this so I don’t have to click through to Instructables just to find out what electro-etching is. A new way to sharpen a knife? A decoration technique? A way to remove rust? Just one more sentence saying “Electro-etching is a process that creates texture differences on metal surfaces for decoration,” would be perfect.

    Alternately, choosing clearer pictures (showing the results) would work just fine, too.

    You actually make it appear so easy along with your
    presentation however I in finding this matter to be actually one thing which I believe I would by no means
    understand. It sort of feels too complex and very broad for me.
    I’m taking a look forward for your subsequent submit, I will attempt to get the hold
    of it!
