Trust me I dont have the issue of having to sharpen in the field due to kills and what not! If I put my three BHds in the dirt with no meat I am going home mad and will sharpen there!!!
Seriously though due to being out and away, maybe on kayak or just away from the truck (eastern NC) I have a sharpening kit that goes in my bag. 6" good file, a small diamond block (DMT I think?) and a piece of buffalo leather that is engrained with polish from years of use. it is small and light and I have used it since I was a kid.
My Dad had me sharpening knives, axes, machetes from the time I could walk. I can sharpen most anything with my eyes closed. but just the ease of my little kit works anywhere I go.
I dont know if the edge is "honed" "polished" "serrated" or whatever name you want to put to it; I do guarantee when I get done with the file, just a couple licks on that hone, and then I strop a few stroke on that leather if you slip with it you wont know your cut til you feel the blood running. Really I can sharpen most my knives at the end of the day with just the leather?
DD said it above, just how dead you want em?

Edit: my good knives dont get on the file just the block - lol unless I really have to straighten the edge out.
