Just dipping carbon steel into the copper sulfate solution will plate copper, but stainless steels and those with high nickel content won't plate without electrical current. Copper disolved in acid etchant acts much like copper sulfate solution but the copper sulfate won't further etch your blade or damage the handle materials.

love to see some other pictures of those knives that took the copper. Any pics anywhere?
