A copy is merely a copy. Without variety or diversity, a copy is doomed to failure on one level or another, not only to its own peril but also to that of whomever decides, misguidedly, to trust one.
There was an article about this in Blade a few months ago. Products imitating other, better products, produced within a country that doesn't recognize or respect the concept of intillectual property, or the laws thereof, do nothing but harm to the legitimate knife industry.
It's not only CRK that is suffering from this, but also Strider, TOPS, and many others. Consider the spyderhole, and Glesser's distinct leaf-shaped blade. How many times have they been used outside of Spyderco's reach?
Any popular or effective nuance of knife design will inevitably be carried down through ideas and generations; there are designs that bear resemblance to the Integral lock, or to the Emerson wave, that contribute nothing to those credited with first inventing them. Perhaps this is not unreasonable, since the bottom line will always be a better product to benefit the end-user. But copies of the nature that is relevant here offer no benefit; only the semblance of style and quality, or worse, the false promise of style and quality, which will only detract from the original maker's intentions and integrity. And regardless of capability or legality, that is WRONG.
