yes electro etching is very different than acid etching....you could acid etch a logo by masking everything off and just dunking it in the acid (at the simplest level) just like etching a blade to darken it and just like Damascus etching (except Damascus has more than 1 steel in it) Now electro etching is very different the solutions used are electrolites basicly just lets the electricity flow... so you clip 1 wire to the blade and 1 wire to a hand pad you put your logo stencil down and soak the hand pad in the solution and press it on the stencil....knowing how electricity works when you have the power supply going in DC it just pulls the steel off the blade basicly digging a hole in the shape of your stencil if you run the power supply in AC then as the electricity goes back and forth (as AC does) it picks up the metal burns it and puts it back down something like 60 times a second this makes the logo black.....as far as doing a detailed logo electro etching is the way to go IMHO
