Since it's summer and most of the clothes I'm wearing is of "lighter" build I've choosen to carry my BM 530 99% of the time. I find I can't really go wrong with this knife for EDC purposes.

I also had a mishap with the lock on my Mini Aegis(ended up cutting myself). I'll try to go more into this at a later time once I figure out what is wrong with the lock if I even can manage to.
I'll leave what I already wrote down below since most of it still applies.
-----------------------------------------------------------------------------------------------
For me if wearing pants I like to carry a folding knife which is less then 4oz. But prefer to carry a knife under 3oz.
If wearing shorts I like a knife which is under 2.5oz but especially under or around 2oz. This usually means the SOG Flash I or Mini Aegis(Especially if I want low pocket carry) or the Benchmade 530. Perhaps the Spyderco Delica.
If I know I'm going to get my folding knife really dirty I'll take a Benchmade AXIS lock knife or a SOG ARC lock knife because they are so easy to clean and maintain. So for Benchmade a 530 meets all my requirements being AXIS and having a weight of under 2oz. Other options would be the BM Mini Grip(2.65oz), 940(2.85oz), mini Presido Ultra(3.08oz) or 111H2O(but it's a bit heavy at (4.88oz). For SOG this means the Visionary I(2.9oz), Visionary II (4.2oz)Mini Vulcan(3.6oz), Mini Spec Elite(2.93oz) Or if I want a really strong, easy to clean and fast access SOG I'll take a Pentagon Elite I(4.3oz).
If I think the knife will stay more or less clean I'll take just about any knife. Liner Lock, SAT(assist) AXIS, ARC or Lockback. I really like some CRKT liner locks such as and M-16 13T or 01KZ The Fire Spark is so cool but It's a serious knife and heavy at 5.2oz. I also love the Hissatsu 2 especially great for low pocket carry. The Benchmade Styker is a really sooo cool with G10 handles and titanium Nitrous assist liner lock. Cold steel Tilite is nice but I don't carry it too often(It's also pocket assisted if you practice a lot you'll be an expert at it).
If I want to have quick access to my blade I'll take a pocket assisted opening knife with an Emerson wave or pin. This usually I'll usually take a Spyderco Delica wave, Endura Wave or P'Kal.
I'm not sure I could choose a favorite edc. But the Benchmade 530 would come close. Though another fantastic choice is the SOG Mini Aegis(also good for low pocket carry if you don't want to advertise the you're carrying a knife(I get the goes for any SOG SAT assist knife like the Flask I and 2 Trident etc). There are so many great knives to choose from and I like to rotate my edc. surprised
