My current EDC Folder is a Spyderco WAVED Endura with a plain blade that I got on sale for $55 Can. I also carry a small Gerber STL 2.0 in a slot on my cell phone pouch, I use this knife the most because it does not freak people out when I produce it.

I carry a red SAK Farmer when I am dressed-up and a Leatherman TTi if planning to be in the bush (usually with a fixed belt knife also).

I carry the Endura, a Buck Crosslock and an original Leatherman Wave when on the job.
