I carry both a Spyderco and a Traditional slip joint knife.
The slip joint gets used way more, but the Spyderco is called to duty when I need something more robust or have to reach into an awkward area to do some cutting. Kinda like the way the old guys used to carry a fixed blade knife for heavier use. But then it's really hard to get a picture of it because I'm usually elbow deep into a major chore and don't have time to snap pictures. But I do enjoy seeing how everybody else is using their knives.
