I tend to swap around between a ZT Hinderer flipper, Benchmade Onslaught, and a Spyderco Civilian. The ZT definitely seems to get carried more than the rest, I really love the feel of the knife and it opens very smoothly with the flip stud.
Until recently, for the last 5 years my EDC knife was a Utica Team Realtree folding hunter -it finally broke. I paid 8$ for it on clearance at a T/A truckstop... seriously one of THE best knives I've ever owned for a cheapy... I used it daily and it took tons of abuse. I even used it to cut off a torn mudflap.
Carrying a Karambit II now. Its not really practical, and Im looking for something else.
Gerber Ghost Strike. I sometimes carry it in the belt sheath in the horizontal configuration, but other times carry it in the ankle sheath. Great little knife!
I generally have a ZT0750 on my left side, and a ZT0350 composite on my right side.
The right side gets switched up every so often. I'll also carry a Kershaw Rake composite, a Kershaw Leek composite, or a Kershaw JYD composite, or an Al Mar Falcon when I want to be fancy.
When I don't want to carry a knife, I'll tote a Kershaw Chive or a Kershaw Shuffle.
The blade on the multitool is partially serrated, which is nice about once a month. That blade also gets the abusive tasks like cutting tubing off of barbed fittings.
