Never understood the appeal of the Havalon.
Find a quality knife. Learn to sharpen it - a skill that will last you a lifetime. Create memories with that knife, take it everywhere, and pass it on to a youngster and let them do the same one day. I still cherish the hunting knife my father gave me that was his father's, although I'm too scared to carry it in the field.
I use a Helle Wind. A gift from a good friend. It weighs something like 3.x ounces. I can get it to shaving sharp. Last year it broke down two caribou without being re-sharpened. Heck, I didn't even carry a sharpener in my pack. It can function like a pry bar if I need it. Baton wood, cut cord. I even cut through caribou rib joints with it to make dinner one night. It's done heavy work on moose too, and I haven't wanted anything more.
