That Vagabond posted earlier is sexy. I've got to get around to picking one up...if Swissbianco ever puts them back up on his site.
For me, my number one is the Classic. I have had the same sapphire Classic for the last 7 or 8 years, and it is still going strong. I am looking forward to being able to travel with it without having to check a bag. I have others, but this is my go to Classic.
My second is the Camper, a great outdoors knife. I was on the fence about this one or the Farmer, but I use the secondary blade far more than I do the awl.
Third place, the Executive. It is unique enough to where its tool load out isn't duplicated by anything else I may carry. It's a fun little knife that demands pocket time.
