I've got an older Kershaw kit (not impressed with the quality of the new version) that came with three blades that change out to the handle. 1 saw blade, 1 blade about like a 110 buck and the 3rd was a filet blade that I sanded down to a 3" drop point. I also carry a Deperschmidt (beautiful, high quality knife if you are not familiar with Waynes craftsmanship, and.....it has been good mojo). I also have another hand built that I picked up years ago at a gun show with a gut hook. Looks like I am a knife junkie too! The combo above has done everything from antelope to moose, gutless, traditional gutting and or quartered and deboned.
The smart guys I know carry the light units with the replaceable razor blades though.
