If it were my knife, I think I would write a very polite letter, explaining that I have been collecting knives for many years and have come to expect better quality from American made knives.
I would tell them that for the price I paid for their Case knife I could buy 8 or 10 knives made in China with better fit & finish than their knife. Or I could buy one Canal Street and have a knife of exceptional quality and still have money left over from the price of their knife.
Then I would explain to them that they can either replace my knife with one that is made right or I will stop buying & collecting Case knives and will tell all my friends on several knife collecting forums about the terrible fit and finish of the knife I bought. and I will write in the forums in great length about my dissatisfaction with their lack of customer service.
That is what I would do.
For someone in customer service to tell me that the pins are countersunk, is an insult to my intelligence! That sounds like a off-the-top-of-the-head BS answer to shut up an irate customer, IMHO.
Just my $.02,

She went on to tell me they would clean up the knife, polish it out and send it back to me at no charge. I guess I should be greatful for their work, but when I get it back, it won't be long before there are brass pins in those ugly countersunk holes. 
It's just something I can't live with and I WILL FIX IT! 
But, as me dear old departed Mom used to say...."It ain't no jump for a show dog".
.. Short and to the point less said works.
