Hey guys, I'm looking for some help on etching my logo. I make carbon steel knives and usually do a forced patina on my knives, but I am having trouble getting a crisp logo etch. It seems like the porous surface of the patina causes the etch to be soft around the edges. I've been getting clean results on a normal piece of steel, and i'm going to experiment with etching the logo before the patina. Also, I would really like to do a DC etch after the patina to leave a lighter colored logo but it also comes out soft. Any advice?
