SAK's = Pocket protectors of the knife world. They're functional, well made, and cheap, but they have absolutely zero sex appeal.

MacGuyver isn't cool?
I've been carrying my Victorinox Cybertool 34 every day for about a decade and until recently it was my only SAK. But last week 4 new SAKs arrived so I have some different options available. But for going out during weekdays the Cybertool will still be my 'must have' tool - I'm a computer tech and the Cybertool is more useful than any other tool in existence.
A few months after buying and immediately EDCing my Cybertool (not that I knew the term 'EDC' back then), I bought a Leatherman Wave. I figured that since carrying my Cybertool was so very useful then the only thing more useful would be to carry two multi-tools. They are a really good combo - the Cybertool doesn't have a file or saw or serrated blade, but the LM Wave does and the screwdrivers are way better on the Cybertool as well as having the 4mm hex driver that I have used MANY times (for hex nut on parallel port, serial port, VGA port & the hex nuts that screw to the case for attaching the motherboard).
Now I EDC my SAK + Wave + Leatherman K502x.
This gives me a lot of options, but when I need to open a package in front of non-knife people I use the small blade of my SAK - no one blinks an eye. I know I have a decent blade on my K502x if I should ever need something bigger and stronger than what my SAK offers. But after owning and carrying the K502x for a year I haven't yet needed to use it - I carry it 'just in case' but my SAK is handling my every day cutting chores just fine!
Now for camping and weekends and evenings I have several choices, as well as my Cybertool 34 I have:
Alox Cadet (slim & light)
Alox Farmer (fairly slim & includes saw)
Ranger (fantastic camping SAK - has saw, file and all common tools)
Trekker (bigger SAK with locking blade)
I don't go camping with only a SAK, but I don't go camping without a SAK either. I don't like to leave the house without a blade of some sort, but a SAK is great for more than just the blade - it provides a bunch of useful tools to handle a huge variety of everyday tasks. Carrying a bigger knife is fine, but it should be as well as a SAK not instead of one.
