For the last 5 or 6 years I switched form a large SAK to a mid sized folder (3.5 to 4") and a small SAK. I still carry my Ritter Grip, BM710, and Endura, etc. part of the time but over the last few months I've started to carry smaller folders more often. I find them more comfortable to carry, they stay in my pocket better, and are easier to handle for smaller jobs like pealing fruit, opening a letter, etc. I've become very partial to the BM Mini-Griptilian in a plain blade and the new Kershaw Leek in S30V and G-10 scales. Both are great EDC knives (Delica is another but already mentioned), especially if you add one of the small SAK's to your pocket. I also keep a large Cold Steel fixed blade in the SUV for camping or other unexpected situations.
Good Luck
PS. And the Mini Maxim as already mentioned.
