My favorite and most used knife over the years (for butchering. . at home) is a Chicago Cutlery 5" boning knife, wood handle. They are not the most expensive knives in the world, yet sharpen up fine and hold an edge fine. They hold well and are shaped well to do what I ask of them.
Believe it or not, Buck made some (really)cheap Walmart kinda knives a while back, solid plastic sheath, same plastic handle, that work quite well for getting meat off the carcass. Keep it kinda small for boning off the carcass, keep it medium sized for the rest. Keep em sharp.
