I have several from a $10 on sale special direct from Buck, to a unused, unsharpened 1970's Kalinga in it's case, and a as new 1970 110 with sheath, and like them all.
I have carried a Buck stockman in my front pocket for several decades
As for a favorite maybe a 110 I got for Christmas from my parents over 40 years ago that has gutted well over 50 big game animals.
