You have a right to expect no cosmetic flaws on a brand new knife that you pay good money to purchase.
If you plan on using it, then I really don't think it will matter much to you after awhile.
I believe Ka-bar will treat you right with their customer service and exchange the knife for another one, if you want them to.
If you plan on using it for work and play, I suggest you go to your local hardware store to the plumbing department, buy five, size 15 O-Rings (1x3/4x1/8) and roll them onto your handle to fill in the grooves. You will get a much better grip on the handle, especially when your hands are wet.
It's a great knife; I've been using mine for over 44 years.
