I use a folding utility knife with linoleum blades for some of the skinning.
Next best tool for me is a Becker Necker. Perfect size and shape for me and really holds and edge and its light and small.
Sometimes I grab a Mora too but does not hold an edge as well as the becker.
The Kabar comes out when I need to lop of a leg etc.
Probably use the becker necker more than any though.
For sharpening I use a DMT double sided folding sharpener, red and green.
Best and most handy sharpener I have found. I have even used it to sharpen scissors and
dull sausage grinder blades etc.
