I will never buy from this brand again. I have sent my ZT 0560 back to Zero Tolerance three separate times. The first time the lock would fail with minimal pressure. The second time was because the detent had flattened and was rubbing the blade and there was audible blade play when I shook the knife. I received the blade back and there were scratches on the tang along with blade play. I decided to write the knife off completely because it was nothing but trouble by that point. So, I put it away and decided I would deal with it later. After a time when life had calmed down a bit, I sent the knife back in. This was about a month ago. I just received the knife back today and it doesn't appear as though anything has been done to correct the play. In fact, I honestly don't know what they did because there is zero information on the packing slip. I know they sharpened it and that is it. So, I paid however much money to ship it to them so that they could sharpen it and return it to me. I can sharpen my own knives. Again, I will never ever buy another Kershaw and I will tell everyone I know to avoid them like the plague. I am disgusted.
