Hmmmm. . . . maybe the moderator should participate in the thread, huh?
My fav folder is my Spyderco Native III. I had an original Native that was my first Spydie, and I loved it dearly, but I left it in my wife's car one night and it happened to be the night some kid ripped off her stereo and my pocket knife. Last year a good friend had a new Native III sent to me, and let me tell ya, they've only improved the thing. I loved my old one, but this holds an edge better (better steel) is much more comfortable to use, and the clip is about a hundred times better (frankly, the old style clip was an annoyance at times.)
Fixed blade? Alan Folts "Mantis." It's not really a utilitarian knife, but I use a folder for most of that anyway. It's very good at what it's designed to do, which is hide out almost anywhere on your person, weigh next to nothing, and yet give a very good poking/slicing blade with a hand-filling, secure, ergonomic grip.
