I made a point a few pages back which is largely ignored.
There is one side to this argument who declares that any business that copies something is a thief and in particular the Chinese. The other side?
They are ALL thieves, every one. Each builds on the innovation of it's predecessors. Each copies the lines and features of the competition. Most of the knifemaking world of folders copies the Michael Walker linerlock. Not one I am aware of bothers to send him a dollar a year for his invention.
Of course, it's not really new, Camillus had one on the two blade electricians GI knife. How far back does that go? If you bother to look into knife design much of what we enjoy now has been around 50-100 years.
Some can claim they stand on higher moral grounds but it's usually internet chest thumping. This is where they think they can establish their place in a social pecking order - but real point of the forum is to discuss the knives - not the ego of the owners.
If anything one of the more exciting things in knives of late is Chinese manufacture, especially their original designs. If some choose to ignore or boycott them - so be it. Cheap imports have always been a significant force on the American market, after all - since Sheffield was the main maker of knives used here. They made most of the Bowies now highly valued in collections.
As just one example of IP - just what knife did the Kabar copy? Because they did, and that knife preceded it by about 40 years.
The Marbles hunters knife.
I guess the Marines bought from thieves and forced our brave fighting men to use them, too. Or, just maybe, there is no IP unless it is protected by patent and copyright. Lacking that, tough. It's a free market. Here and in China.
