  1. Might be worth a try at that price.

    Seeing the initials ZT in print made me immediately think of Zero Tolerance knives from Kershaw / Kai…not a bad thing, but could be confusing to newbies.

  2. The article talks about “skinny little optics”, but leaves out the width in the dimensions. Neither is it listed on the ZeroTech website. -Basic info that would be nice to know. Any help?
