I got my first Buck knife, a 301 stockman, in 1967 and carried it till the early 90's. My dad was a case man, and carried a old Case peanut from 1937 to his passing in 1981. Both knives gave a life time of great service.
I still have a Case or two around as well as my old stockman and a newer 303 cadet. All are exellent knives. It's just a matter of taste and mood, which one I'll drop in my pocket for a day.
Case gives me old style jigged bone handles and carbon CV steel. Buck gives me near indestructable synthetic handles and stainless steel for wet saltwater conditions.
It's like a hot dog or a hamburger, which do you feel like today? both choices are good, and will feed you.
