My usually EDC/rotation:
Flashlight: Eagletac Clicky in left rear pocket next to notepad (currently D3A Ti with a rechargeable 14500) - I have two other Ti Clicky's (AA, and CR123) that I used before the newest Ti version came out. **If you like larger more rugged lights, I am very impressed with the SF Tactician for lighting up a room or even widebeam outdoors.
Multitool: LM Juice S2 - currently housed in a small Lowepro camera pouch with other EDC items; although the pliers are a little small if you regularly loosen/tighten larger bolts, I've used them for removing hundreds of long carpet staples from wood, and used the screwdriver bits for driving in dozens of 1" wood screws in windows when my toolbag wasn't with me. **For larger pliers, I like the Victorinox Swisstool Spirit X.
Knife: I rotate them and sometimes carry a pouch if not in my right rear pocket. Right now, my most carried knives are (in order) the CM154 Buck 110 LT (SKBlades), ZT 0909, numerous Buck 112's (stock and C&C), and BM Boost (w/custom Micarta scales - they don't stick to your pocket), and sometimes a BM 575 or 20CV/Micarta Buck Vantage (SKBlades). In summer, I'll often carry the Spyderco Yojimbo 2 (M4), and on the MC the BM Stryker 2 (rear pocket). **Side note, my favorite EDC knife is still the BM 520, but since it's DC'ed I don't carry them much... maybe if I get a fourth.
***Side note 2, if I'm expecting to cut things like R20, I'll add a box cutter.
