it ain't just emerson. laser engravings dont last at all. for any brand. I have Bucks and other brands that are the same as the ops, not as cleanly removed but faded badly, but from use though. not from chemicals used to clean. I'm not a fan of laser engravings due to this wont last. prefer stamped in the steel or acid etched into the steel methods. that said its harmless to the knife as being a knife and used as a knife. also collectors who dont use their knives, wont notice this happening.
