Armchair commandos may believe anything sharp will make a good skinning knife, this is simply not true. Certain types of knives are much better at skinning wild game than others. Let’s take a few minutes and talk about types of knives to stay away from and types to consider.
For most applications the smaller and thinner the blade the better.
The easier the knife is to clean, the better. This should exclude multi-tools and knives with accessories, such as the Swiss Army knife.
High carbon steel blade that holds an edge and is easy to sharpen.
Examples that come to mind so far are the Gerber Big Rock, Gerber Profile, and Case pocket knives. I have seen more deer skinned with a Case pocket knife than any other brand of knife. Old guys do not mess around with fancy or expensive knives. Experience says go with what works. For most applications, a Case pocket knife will do just fine.
