Hiking - CRK mountaineer 1. Its small, lightweight and can handle most tasks.
Camping - CRK Shadow IV. If Im not hiking I dont mind the extra weight, also feel(unwarranted maybe) that this knife can handle a bit more abuse than the mountaineer 1.
With all that said, I dont use these knives much. For camping I typically carry my JK camp knife and while hiking I carry my custom knife or EDC from JK.
