I've struggled with this issue over and over again. I know that, from a purely objective standpoint, country of origin shouldn't matter. An experienced user/collector should be able to spot a quality knife no matter where it's made. It has been proven time and time again that Taiwan can produce VERY well made knives, from budget Cold Steels to more expensive Spydercos.
However, for some unfathomable reason, I get no pride of ownership from a knife made in Taiwan even though I've tried a few and know they are well made. I prefer to carry something made in the US, Japan or Europe. My CS Voyager, for instance, is a fine knife with a very decent price tag. I would carry and enjoy it a lot more if it were made in the USA (or Japan like the older ones). There are some Spydercos I'd love to own, and would if they were made in the US. The only reason I don't buy them is that they are made in Taiwan, even though I absolutely understand that they are great and have recommended them to other people.
I also avoid Chinese knives. I just don't enjoy them and I realised I have no use for something like a Tenacious (I've owned one for ages and never carry it). When I'm looking for an inexpensive knife, I'd rather have an Opinel, SAK or Douk Douk. I can't seem to warm up to budget modern knives.
