Klause,
Not too long ago, I received a one week notice that I was deploying for Iraq as a Corpsman with the Marines. Being a bit of a swapper and trader, I was caught without a fixed blade on hand and a week to be ready to deploy. I went to a local knife shop and paid full retail for a Buck Strider fixed blade.
For the money, I had expected nothing short of perfection and like you, I had a few beefs about the blade. Enter Joe Houser and the Buck Family.

Joe had me send the blade to him personally. Withing 48hrs, It was back in my hand and absolutely perfect.
My primary complaint had been with the grind (do a search and you will find my posts about everything) so Joe sent it over to Wild Bill (Buck's custom orders guy) and all was taken care of.
Rest assured that if the folks from Buck know of your problem and say they will fix it, IT WILL BE FIXED.
I can't think of another company that goes all out to take care of their customers the way they do while still surviving in such a competative market.
BTW, I just arrived back in country last Friday and the Buck Strider Fixed blade and 880SP that I carried for the entire push into Bhagdad never failed. They remained sturdy and 100% reliable throughout. (I think I made several converts withing 2/23rd Marines.
I can't wait until I get the money saved up for my Buck Mayo. That's next on my shopping list.
Enjoy your knife.
Doc
