Another good EDC blade (my brother has one) is a Buck Vantage. They come in two sizes, one larger and one smaller. You can get various different steels and various different handle material. If you want good steel you can get S30V.
The current line of ZDP steels only come in the British racing green handle. The black handles come with VG10 steel.
I also have the big barrage. Yes, it is a brute but I love the M390 steel. No, it is not considered a switch blade, just a spring assist. You have to push the blade open with the thumb stud before the sprint catches and flies it open. I would love to have a mini in M390. They also have some mini barrage in 154CM steel.
I own a Sypderco Stretch in ZDP-189 and I have to say that is good steel. Depending on the size of knife you want to carry you can get it in a Dragonfly 2, Delica, Endura, Stretch. All great knives.
You can also check out a Spyderco Chaparral.
Check out a Benchmad Mini Barrage in M390 steel. Good stuff.
Not sure what you think about 154CM but I think it does very well. I really love my Benchmade Torrent for EDC. It has a 58-61HRC. Blade length is about 3 3/4″ though so it might be a little big for your liking but it has a low pocket clip so it sits low in the pocket!
