NOTE: When I lived in Silicon Valley I lived with and almost married a Chinese women from Shanghai. I've had many dozens of Chinese friends in both CA and IL. I'm quick to make friends with a lot of different people.
I have not yet knowingly purchased a Chinese made knife, I just see so many other top notch knives being made in the USA, EU, Taiwan, Japan... that Chinese knives are not of interest to me. I do not have a lot of money so I concentrate on other goods.
Spyderco has to tough call. Make knives in China; fewer, the same amount, or more knives can be made in China. As far as the vast majority of Chinese manufacturing being legit goods, I highly doubt that. China is already targeting Spyderco. That is where these knockoffs all probably come from.
The Chinese have stolen $225 to $600 billion worth of intellectual property from the USA every year since they entered the WTO in 2001. That adds up to around $9 Trillion in theft. In that time, the USA has lost 60,000 factories & >5 MILLION manufacturing jobs. I do not have the numbers for the UK, EU and Scandinavian countries but they also lost many factories and manufacturing jobs. This IP theft has real consequences.
