It's morally wrong to profit off the work of others without investing anything of your own. Ganzo does that both by using patented technology and by blatantly copying designs. As I've consistently maintained, not all legal acts are moral and not all moral acts are legal. As for foreign patents I don't check on them, and I think ignorance of their practices is a totally acceptable reason to have purchased one of their clones, but I would, once made aware, seek out a product that was not using others intellectual property.
And that (bolded by me above) is all the justification repeat buyers of clones and even counterfeits need. "It's legal where they're made, so what's the problem?"
I bought a Ganzo a couple years back, before they were really getting discussed much here. I wasn't familiar with Benchmade's various models, so the copying aspect was lost on me, but it was immediately apparent that the knife had some design elements that made no sense, one that stood out being screw holes for switching from right- to left-hand carry...for a clip other than the size/shape included with the knife. It was - in retrospect - copied from the grip design of a different knife than the one whose clip design was actually used. I gave the knife to a friend because, well, he needed a knife and I didn't care about the Ganzo. Then I bought another one, a more blatant copy of a Benchmade (as I learned after the fact) and arguably a nicer knife than the first. It was, for all intents and purposes, a perfectly acceptable knife for the money, which is typical "praise" for a cheap knife. It was shortly after the second purchase that I started reading about Ganzo's propensity for copying other manufacturers' designs, sometimes mixing features from multiple sources.
Now, what happened after that is possibly the
opposite of what usually happens. Rather than me being someone who wanted a Benchmade but didn't want to pay the price of admission and thus opting to buy a knock-off, I ended up buying Benchmades
because of the knock-offs. I had no prior experience with them, but felt compelled to educate myself. As a result, I now own a handful of Benchmades. Meanwhile, that second Ganzo wasn't followed by a third. However, I can't fault the knife for its manufacturer's unethical behavior, so it occupies a place in my budget EDC rotation for as long as it functions. Time will tell if it outlasts the cheap MTech, Taylor and Gerber folders that I once bought for similar purposes. Of course, the vast majority of people looking for an inexpensive knife 1) are going to consider the specs of most Ganzo knives quite decent for the price and 2) aren't going to research the brand much, whether here on BF or elsewhere. Those who do might not care, seeing Benchmade as somehow the "bad guy" for charging what they do. It's bound to happen.
For any music/pro audio dorks like me, the closest parallel I can think of is Behringer, who was frequently accused of copying established manufacturer's products by way of Chinese factories. There was talk of cutting corners on actual construction techniques and components, but as with so many things, fans of the brand justified repeat purchases by saying "Brand X charges too much, and should lower their prices if they want people to buy their stuff."
