I'd have to say there is a fundamental difference between 'counterfeit' knives and 'clones'.
This.
I've made this point over and over in the years I've been here. It always causes hurt feelings among folks unwilling /unable to understand the difference.
Furthermore, I've stated that copying is a good thing. Regardless if it's knives, computers, or paperclips. Copying is the fuel for innovation. Sorry folks, but nobody is entitled to sit on their laurels in perpetuity. Not even when one enjoys the benefit of patent, which have very definite lifespans for the very reason of not stifling the market for a product.
