My current EDC is a CRKT M16-13Z. I love the hell out of it. It's not as big/badass as some of the folders in this thread (I like the look of that Kershaw Tyrade and might order one, but it looks a tad large for my hands and pockets), but I find it to be just about the perfect sized blade for anything I throw at it. Small enough that it doesn't weird people out, spear-point shape which I love, a little serrated (but not too much). I've used it for everything from woodwork to slicing food on the trail to prying a cork from a wine bottle when I had no corkscrew. Locks up stiff as hell and I love the assisted opening. It was my first serious knife and it goes everywhere with me.

I just ordered a Woodsknife Wk2 folding puukko, I'll post my thoughts on that when it arrives.

Anywho, lots of cool knives in this thread, I'm looking forward to slowly acquiring a larger folder collection.
