My god! You guys are such pushers!
The ZT is a good knife. However, and this is a big however (notice I'm using "however" and not "but" for what I hope are obvious reasons), the differences are usually only perceptible to the educated knife knut. Regular people, mundanes really, who just use knives to sharpen pencils, open packages, and maybe kill a bear, won't notice anything special. Only an actual accredited knife knut can feel the differences, the slickness of the bearings, the mind-blowing edge retention from boutique tool steels manufactured by indentured Martian metallurgists, the liberal and sometimes frivolous use of titanium and carbon fiber, these things are not available to the mere gas-station knife user, regardless of how many Harley Davidsons they have ridden upon.
So, really, is it worth it? Probably not. Stick with a lovely CRKT knife and blow the extra cash on an X-Box or something.
