My go to all around butchering/carving/fish fillet/kitchen utility knifes are Victorinox-Forschner 5" semi flexible blade boning knives. One with a curved blade and one straight. You can pick them up for under $20@ and they will last a lifetime. I think mine were about $14 delivered brand new. For $25 or so you can get them with Rosewood handles instead of rubber/composite. They are all I use for butchering a deer. They take a razor sharp edge, hold it, and are easy to touch up with a steel.
