I'm a big fan of the Buck 110.
My father gave me one prior to my first big game hunt. Down through the years I have acquired and used many more expensive and exotic knives.
Nowdays I've pretty much come full circle and that 35 year old 110 goes hunting again. It's not only for sentimental reasons - the 110 is still up to the task.
For the money I don't think there is a better value on the market.
