I can see where a professional engraver will have very little desire to try to pickup a engraving job that will only make him mutter to himself, under his breath. There is enough work these days that it must be nice to tell a client that it should be done right on not at all. Perhaps someone may not mind trying to do it the hard way, if the job is small, and they have nothing else to do. Besides what cost more the engraving or the annealing and then recase coloring? Might be cheaper and faster to just do it the way Ken suggest than pay him extra hours of labor to do it the hard way.
