Deer and elk: havalon + 3 extra blades, Vicky, cheapo pull-thru hand sharpener for Vicky.
I sharpen the Victorinox prior to trip via lansky to where it takes off swaths of arm hair without effort.
Moose: add a knife with some backbone, because the havalon bogs down in thick hide when skinning.
I wouldn't be without a Victorinox when boning an animal - the flexible blade makes life grand.
Brad's Opinel units look interesting.
