The ZT0566 is my first EDC knife that isn't a "use it , loose it, buy another Big5 cheap o".
I don't have much experience with decent folders. That said, this thing is built like a hank. Heavy and solid. I like heavy when it comes to a working blade.
Just about every review I've read says its a great deal at full price. At $99 it's a steal. Especially when you have an iron clad lifetime guarantee.
