I would say a lot has to do with you. Do you care about the stamp. If you don't like it it may easily be worth $10 rather than time spent finding one without -which may or may not be cheaper. Also are you planning on ever selling the knife. While a no stamp may get a premium on a LNIB I doubt it gets much on a well used, and no extra on a keeper. I prefer no stamp knives, but it really isn't a deal breaker. I think in a year or 2 there will be few that even no what you are talking about when you say no stamp.
