I have used an old timer, and it worked fine until I lost it. Then I got a gerber gator and I didn' t like it because it got dull so fast.

So now I use my Buck Pathfinder that my dad gave me when I was young. It ain' t easy to sharpen but it holds an edge for a loooong time. I also have a buck pocket knife that I use sometimes.

I will never use anything other than a buck knife. I had to buy a sharpening kit to get the thing sharp but it gets so much sharper than any other knife I have ever seen. Heck I once shaved with my knife on a backpacking hunting trip.
