I also use case knives. the trapper and trapper lock are my favorites for skinning. I only use the cv metal. The edge will last about 2 deer before needing sharpened. it only takes seconds to sharpen as well. I grew up using buck knives but switched to case knives after using them. After I debone, I like to use a fillet knife to butcher with.
I even named my boy Case..ha ha
