G-10 Harpy, fully serrated. This knife is always in my back left pocket. My other carry knives get switched between various models, and the Sifu stays put, but I can't swap the Harpy out for another knife because there's nothing else in its class. I recently sharpened the Harpy, which I had been dreading doing since I got it, and was pleasantly surprised at how easy it sharpened up. At $50 it's gotta be one of the best deals out there. I fully recommend the G-10 Harpy to everybody.
