I hadn't thought about lazer engraving. The most lazer engraving I've seen has been on newer stock coming where the companies have used it to inscribe the karat and logo. The problem I'm finding with them is they aren't very deep and I have to watch not to polish them out after sizing. I went to the link you posted and had a look at the outside lazer work. Are the designs fairly deep, will it last for a few years at least and can it be done on an irregular shoulder shape?
