At work: Buck tri-blade pocket (peanut) knife.
Nights and weekends (until a week ago when some Delta baggage punk snagged it out of checked luggage on a flight back from Atlanta): http://sogknives.com/store/FSA-98.html
Newest purchase (still waiting on shipment): http://www.bladehq.com/item--Boker-Kalashnikov-74--103 (Wasn't too happy with the SOG's tendency for the safety latch to slide closed, which is a GOOD safety feature if that's your stance)
In the boot: http://www.amazon.com/Smith-Wesson-S.../dp/B001606XS6
In one vehicle: http://www.spyderco.com/catalog/details.php?product=372 (love the action on this one)
In the other: http://www.gerbergear.com/Essentials...knife_22-48443 (steel is junky)
Donation to girlfriend (I miss this one, strong blade, tight lockup): http://www.kabar.com/knives/detail/117
