Threads like this are amusing. In my own case I have dozens of knives. I'd say about 70% of them are my favorite and the other 30% I like or would not still have them.
As I sit here typing this I have one Mutz custom custom canoe, two Bulldog large stockman, a Case Copperhead, two Copperlocks, one mini Copperlock, a small Schrade stockman, the Vic Classic I won in Knife Crazied's giveaway sitting between me and my computer. I have a Fight'n Rooster canoe in my RF pocket and in the EDC drawer of my desk I have 16 other knives by Gerber, Kershaw, Spyderco, Schrade and Benchmark.
I will pick up an carry any one or more of these knives depending on anticipated cutting chores. The one knife that has seen more hours in my pocket than anything else is my Benchmade 812S mini-AFCK. Next is the Schrade 194OT which is a slightly smaller "traditional" design, but when you look at them side by side there are striking similarities between them.
I am currently "in love" with Copperlocks, but time will tell if they or others will take over the "most carried" title. I like knives in general and it is neigh unto impossible to make an "absolute favorite" pick; it can and does change often.
I post much more in Traditionals than in General because that's my current strain of knifitis.
