I like my buck knives.have a cheap folding one retails around twenty dollars.skined and completly butchered two deer . cleaned a few ducks.still sharp does have a small nick in it.also have a higher end one non folding think its a ranger.i gutted my deer last year with it.
Replaceable blades is the only way I work. I can buy a 1000pk and make them last forever. I only use about two per pig and takes all of 30sec to change one out. But I still take my buck and wet stone! I personally like sharpening my knife, it's fun, easy and fast once you get it down.
