Perhaps I simply don't understand the problem. If the grind were radically off center, a true defect, that would be one thing, and I'm sure KA-BAR would address it. But if it's just a little off center, that is another thing entirely.
That's so easy to correct yourself at home that I can't understand sending it back to KA-BAR. Just my personal opinion, but too many people get really nit-picky about things that really don't matter. I don't know about anyone else, but I buy knives to use, and I use the holy living heck out of them. Since I do use them, they're going to need to be re-sharpened anyway, and correcting minor flaws in a grind is only a matter of a few minutes. You can probably fix it faster than you can get to the Post Office to mail it.
Just my two cents.
