Wow that is great!
It is a CPK knife minus the 3V steel and associated heat treatment, fit and finish and grind accuracy
But nevertheless it is CPK (look alike) knife!
if we focus on performance to price ratio, I do not think this a good buy since it lacks all the elements making it a high performance knife. Even though it costs half the original, I do not think it will perform half as good. That being said, if they manage to make a decent knife out of this excellent design, i think it will worth buying. Not many people can afford CPK or have the skills/knowledge to get one.
