The "Um, Wow." refers to making a judgment based on experience with only one knife of the ones that you cite. I'm looking at my ZT0200, 0350, and Spyderco Orange G-10 Military as I type this. Speaking of oranges.

(My Orange G10 Tyrade is in my pocket so I'll leave that out of the discussion.)
My measurements were an attempt to show that the liners on the 2 ZTs that I own are almost twice as thick as those on my Military. The blades are about the same thickness for all 3 knives. Personally, I haven't used any of these knives enough to cause a failure or any other problem with the lock.
The best thing that the OP could do before he chooses a knife is handle the ones that are recommended by the folks here in this thread. Or he could follow the BF tradition and buy them all. :thumbup:
