OK, I gotcha! I finally see what you mean. That's a good test for observation. Boy, I don't have an answer, except one may be older than the other and they changed their etching procedure. Try contacting RoyalShave and see what they say about it. I wouldn't use, strop, or do anything to it until you've contacted them. Good Luck and let us know what they say. I suspect the shave will be the same though.
