I will not buy anything from pretty much any foreign country. Their knife designs seem pretty bizarre, and they frequently use inferior materials. That being said, exceptions to that would be Germany, Sweden, Finland and a few select others.
Also, although there are some outstanding knives produced presently in the USA, I have bought very few pieces dating after 1990. Instead, I focus on pre-1980 american makers.
For instance, I have never owned a Schrade made before 1975 that I would consider crappy. Also, older Camillus, Colonial, and real older Imperials were solid performers in their day.
I like tacticals, but would rarely carry one. How could you not like the smoothness and fit of a 3-blade medium stockman in your pocket?(I'm sure someone will respond to that in the negative)
I just like the fact that these older knives were not always made with mass production in mind, have good heft and weight to them, feel solid and perform well, and were probably assembled by an actual human who cared about the product he was making.
Zytel and polycarbonates may outperform Delrin and jigged bone, but to me they feel light and cold.
(Allright, me getting off my soapbox)
