Just got my 0566BW in. I've got to admit that I am a bit underwhelmed. I like the size, and the looks are very appealing, but the assisted opening is the worst of any Kai product that I have bought. Of course, I've done nothing to help it out yet and perhaps I am a bit spoiled with the otherwise outstanding assisted openers that I have bought from Kai.
Over the weekend, I'll read this thread in its entirety and see if there are any tips. Otherwise, I'll just start cleaning and adjusting until I can improve it some. First time that I have bought a ZT and not been happy with the product right out of the box. But...I'll get it right.
Also need to replace the G10 scale with a custom CF.
