I like a US-made Buck "Solitaire" for everyday carry if you can find one. One blade, just big enough to do just about anything but won't terrify anyone (this is an issue in slurban America, I have found). For formal occasions when you can't load up them dude clothes with hardware, a little US-made Buck "Solo" will do a lot of indoor work and be invisible.
For outdoor heavier duty cutting, I like a Japanese-made Spyderco "Green Endura Plain Blade" that my son took to Afghanistan twice w/the USMC and gave back to me when he separated after his 5-year contract.
The problem with Case folders is I can't make up my mind which I prefer, and that can get expensive....
The Endura is a great knife, VG-10 is an amazing steel. My personal edc is a spyderco native, its just about perfect. I used to carry a spyderco Manix, but realized after awhile that its a bit large. If I wasnt carrying the Native, Id probably have a Delica with a VG-10 blade.
