D2 minigrip--holds the edge forever, great axis lock, pocket friendly
M16 11K -- very pocket friendly, fun, great action, reliable liner lock, partially serrated blade, feels good in my hand
Paramilitary -- incredible blade and steel, superb ergonomics, g10, nearly the best lock out there. This would be "the knife" if it weren't so huge and didn't stick out of my pocket. But I carry this 80% of the time.
The honorable mention is my greg lightfoot urban shark....great little knife, I use it in sheeple situations.
