When I lived in and was traveling in Asia (Taiwan, Hong Kong, Korea), my carry knife was a regular-sized Victorinox Spartan SAK. I was never questioned about it in any airport. However, I have heard different experiences by others. I left Taiwan in 1992, don't know if anything is different.
Another point to make is personal appearance. I think a lot of airport security will look at the same knife carried by 2 different people, and if they perceive one guy as a bit scruffy, they might more likely view him with suspicion than a nicely-dressed person. That is totally unfair, but
people do it all the time. Of course, I talked to a businessman who got hassled over a small penknife that was in his briefcase.
