I had a look at mine and I can see what you mean. There is a visible gap between the metal of the blade and the stuff of the handle; about a millimetre each side. However, tightening the screw that goes through the pivot does affect the movement. I think there's a washer out of sight deep inside, or something.

I live in the UK, and my blade was very tight when it arrived so it wouldn't be mistaken for a gravity-assisted knife by Customs. I had to loosen it. It sounds like your knife is too loose and needs to be tightened.

I'm sorry that you're upset about it. You should know that many of us own these knives and know that they are not as bad as you imply. They have a good reputation; in fact so many credible people praising them that you will have an uphill struggle changing anyone's mind. I have to say that your tone is not helping your case.
