The CRKT Nirk is designed by Glenn Klecker; Nirk stands for Nathan's IRreducible complexity Knife. Intelligent design advocate Michael Behe coined the term "irreducible complexity," it means "a single system composed of several wellmatched, interacting parts that contribute to the basic function of the system, wherein the removal of any one of the parts causes the system to effectively cease functioning." There are just two well-thoughtout pieces to this knife, plus a blade pivot screw.
