I use an electric etcher with a stencil to put on my maker's mark. What's the best way to put a mark on an etched blade? I've got a couple of blades coming up with nice hamons, and will finish them out to 1500 or so and etch in ferric chloride to bring out the hamon. Do I need to put the mark on first before the FC etch, or will an electronic etch work properly on top of a FC etch?
