Daily. As much as I love the newfangled knives, I still carry a bone-handled stockman or trapper every day. Great whittlers, great tradition, and great classical beauty. A jigged bone handled stockman is still something to be admired and used. Three blades, each with it's own style, history, and usefulness. I still remember my dad's Case that he carried for 30 years until the handle gave out and the blades were worn away. One knive, one long history of use, one essential tool.
I occasionally like to whittle and my AFCK, Axis, Wenger, etc are not useful for that unless you are cutting down a small sapling (which isn't whittling).
No matter how many fancy one-handers I will own, I will always carry a small trad. pocketknive of one kind or another. Their traditional beauty, and usefulness far outweight their inconvenience of opening.
