I'm mostly using just a modern, generic, cheap knife. Something like a basic version of a mora knife; http://en.wikipedia.org/wiki/Mora_knife

I'd like to have just a simple, traditional, hand-made finnish knife. But at the moment I don't have a good one. Luckily I have a good collection of old axes and hatchets. When I was younger I always carried a small hatchet with me when hiking or camping. Nowadays I mostly go with the knife.
