I have many, but one of my favorites for 20 years was a Puma White Hunter which I lost several years ago after field dressing a deer. I thought about replacing it a while back and was a bit shocked at the price now. I like Buck knives—good Christian family founded this fine knife company.
I made knives as a hobby during high school (mostly putting handles on purchased blades). My dad gave me his old White Hunter (with a broken tip). I removed the stag handles and replaced them with kingwood, then (like a stupid teenager), sold it. Fast forward twenty-odd years, one evening at a consignment auction house they put a couple of knives on the table, and one looked familiar...
I was able to buy that knife back, and it's now in my desk drawer, and never leaving my possession again! I saw one at a gun show last year- I, too was shocked at the price!
