I have a bunch of knives and if I had to pick one to do it all I would probably pick the green river hunter.....and it cost about $20

I personally carry a outdoor edge sling blade to do the field work on deer and use green river knives for the butchering.

Before I got the green river knives I used forschner and Dexter Russell knives for the butchering.

When I'm not hunting deer I carry a mora in the field.
