Generally, the requirements of a skinning knife and a knife to quarter a big game animal are different for each action. I am not a big believer in changeable blade knives. There are many knives out there on the market in both fixed blades and folding knives of good quality. You want to look at a blade that will hold an edge for both tasks which to me means carbon steel. It takes a fine edge and dresses up easily with a couple of strokes on the stone or steel. A finer blade for skinning and a heavier blade for taking the animal apart. Look at Gerber, and Case for good blades for the money. There are so many manufacturers out there the only way to find what you want is to handle some different brands. Or, you can go with custom knives where you tell the maker what you want. I have never found the need for that.
