For folders, I love Kershaw, and Kershaw is my usual EDC. I also like Cold Steel(cause I like owning big folders, and CS pretty much corners the market there). Spyderco makes good knives, but a lot of them don't appeal to me aesthetically so I don't own as many as I might otherwise. Nothing against the quality, I just collect as much because of looks as because of use. Since I have plenty of good useable folders for my needs already, any other folder I buy is primarily a matter of aesthetics and feel in hand, and while Spyderco has a good feel in hand, the designs themselves often don't hook me at all(I have absolutely 0 interest in the much touted Southard for example, cause I consider it rather ugly). CRKT have a few designs I like, but I usually find something I like more from another company, and wind up passing...they do have some sweet looking stuff in the 2013 lineup though so maybe I'll add more of their stuff to my collection this year. Have yet to see a Benchmade that I want bad enough to pay their prices for, and I can't justify paying several hundred dollars for a single knife, so customs or high end knives like Sebenzas(also a hideous knife that I wouldn't buy even if I won the lotto tomorrow) are right out...once I start thinking of paying a few hundred for a blade, I'm more likely to just opt for ordering a sword or something. I usually shy away from most non-Kershaw cheap knives(they often just feel junky in the hand) but occasionally one will catch my eye, hence why I have a couple of S&W knives in my collection as well.
For fixed blades, Cold Steel, Mora, and Kabar do well for me. For even bigger fixed blades and machetes, I love my Condors and Aranyiks, Cold Steel and Imacasa can be made good as well as long as you don't put putting some work into them to get them useable first(or order from Baryonyx here, and have 42Blades do the work for you).
