I have been on the forum actively less than a year, and one thing I've learned is there are about a gazillion knives in the world. In fact, I have seen knife brands on this forum I had never heard of that are well known to knife enthusiasts: it's been very eye opening for me.
With that said, my criteria for choosing a knife,has changed. I now choose a knife based on 3 factors: what will I use it for, What is the better design for that use, and what is the better steel for that use.
From a personal perspective, I don't buy cheap junk - it's not worth the $15 except Opinel (my opinion). And I'm hard pressed to buy $400 knives (my economic position, and personally, it would really hurt if the blade broke or knife was lost). But I'm not opposed to the $100-$250 range as there are lots of good knives there that should last a lifetime. All these normally use more premium steels (my favorites are 3V Cru-Wear S35V and probably CPM154).
BUT, I carry a Rat 1(AUS8) and 2 (D2) around the place for general work, paired with a Spyderco Tenacious (8CR13MOV). And I like the Kabar Dozier in AUS8 too. And if one of these breaks or gets lost - I won't shed too many tears. I also have ESEE 3,4,6 which I really like because they fit my criteria of features like blade shape, handle design, and materials (1095 ain't bad). And if they break, I get a new one from Esee.
Still, I am always looking at those $300-$500 ones. And someday ...
