Zero Tolerance ZT 0640 Ernest Emerson Video Knife Review

The Zero Tolerance 0640 is the third and latest collaboration folding knife between ZT and Ernest Emerson.

Unlike most Emerson designs, the ZT 0640 has no wave feature for automatic pocket deployment and little in the way of front finger guard (to stop your hand from running up on the blade in a hard thrust) … in my eye, this sets the tone for the knife. This is more of a hard-use EDC blade than it is a tactical folder, I put it on the same self with the Chris Reeve Knives Sebenza or the Benchmade Crooked River.

The beautiful long-clip style blade is made of CPM 20CV, a way overkill high-performance blade steel… Knife Junkies such as myself are happy to pay lots of money to have that alpha-numeric combination written on their blades. The split pea soup green carbon fiber overlay on the handle turns a lot of folks off but, in contrast, it turns me on, as does the knife as a whole. That sounds weird, but you know what I mean.
