I like my SAK's. Carry a small one on my keychain. I'd like to get another one with a little screwdriver. Sure, you could carry around a tool kit with you everywhere. But I'd rather just have a little SAK. They're generally high quality, and I can't really think of something comparable that I think is better. Sure, there's Leatherman, and I do often tote a wave around. But those are generally much bigger, and I'd rather just have a little thing that can fit on a keychain comfortably, and the small leatherman just doesn't cut it for me. I ALSO carry a dedicated folder and a fixed blade as well. I'm one of those guys. They all have their moments. They're popular because they're good quality, everyday carry friendly, useful little tools, that look a lot more elegant and less clunky than the alternatives.
