Right now, Schrade SP7. Great "beater" knife. Use it all the time. Mostly opening boxes and such. Usually I'll carry a nicer knife around when I'm not at work. I must have over 40 different ones. Buck, Gerber, Ka-Bar, Bench Made, Spyderco, Case, Kershaw, Victorinox, Al Mar, Remington, Colt, SOG, you name it. Inherited most of them.
