Before I carried mine for a while, I would've recommended the Byrd Cara Cara in G10. However, this knife is just gigantic. So whatever the next smallest step down in the Byrd line, is a great EDC. These knives are unbelievably well built for the price. The steel is 8Cr13MoV, which is basicall a chinese clone of AUS-8. Which means that edge retention isn't awesome like VG-10 or ZDP-189 or CPM-S30V, but it's easy to put an edge on it. Hey, it's better than 440C. It's a lockback and I have the model with the G-10 handles, which is just awesome. However, the blade is pushing 4" and this is a large, heavy knife. It gives me piece of mind when walking into my murder mart for a Soda, but other than that it's a bit big.
So I'd steer you towards the Byrd Meadowlark G-10, which is a lockback with a 3" blade, or the Byrd Raven G-10, which is also a lockback but with a 3.5" blade. I'd really like to get my mits on a Flight G10 but haven't ever seen one yet. The Meadowlark and Raven are both pretty conventional designs. These knives offer amazing value for the money, are rock solid, and I think look good. And you might as well get the G-10 handled version - it's not much more expensive (I think it's $10 full retail, which turns out to always be less when you buy it) and it's better than the light feeling FRN or the tacky stainless.
Also going to throw out the obligatory "How about a Griptilian?" and "save your money and get a Sebenza! (LOL)."
Kershaw's non-assisted models are great, too. a JYD I is a frame lock with Sandvik steel, the only downside to which I've found is that you need to pay more attention to avoid corrosion. The ergos on the JYD line are great, they have a flipper and the JYDII has a HUGE liner lock, completely rock solid, very thick blades, a good worker. The Skyline is a bit small for my hands but your mileage may vary.
Also, Maybe a standard VG-10 Delica?
and to be a complete oddball, try and find yourself a Browning Ice Storm. aluminum handles, VG-10 blade, razor sharp, neat clip that's integrated into the liners (so it won't come loose on you!" and they're cheap. And light.
If you are trying to pick the perfect knife before you buy it, I would recommend seeing if Youtube user "cutlerylover" has an opinion on it first

seriously, watch some of his reviews, they cover most of the important topics for ECD, and he's reviewed a LOT of knives, from a BM Monochrome to a custom Strider, etc etc.
anyway, sorry for rambling. James out.
