I have the buck packlite and its just okay.
The best I have found, and have been using the last two years, is a pair of victorinox 3.25" parering knives.  One in serrated, one plain.  They are extremely sharp with a few licks from a $4 pocket sharperner and are perfect for breaking down game.  They just plain work at like $7 each.  Made a sheath out thin disposble cutting board material from the dollar store.  Much lighter than the packlite too.  I dont use any of my expensive knives anymore in the field.
