Thread: Etching Questions & Ideas

Some people have managed to do some pretty decent etches on blades using things as simple as wax/nail varnish and ferric chloride or salt water and a battery. It's surprising what can be done with rudimentary tools. Not that I'd try it on a razor as the etch tends to spread as it gets below the surface using these slow techniques (giving you a dovetail sort of shape if you were to cut through the blade and look side on).
