knifemaker here.
I have a sweet collection of whetstones, but I don't take them into the field. In the field, I have an axe file, a ceramic rod (virtually unbreakable kind, very light, about 8" long), a small piece of wood with leather on 2 sides loaded with 2 types of honing compound, and a small diamond 2-sided fold-up "stone" with 300 and 600 grit sides.
A bushcraft knife should be easy to sharpen, compared to a 62 RHC sushi knife. Mora's are very easy to sharpen. Most of the time, a few passes on the ceramic rod and a little stropping and they're back to shaving sharp. The only time I need to crack out the coarser tools is if I've really nicked one. I recommend mora to everyone just getting into bushcraft. They are, hands down, the best value for your money.
An axe file is all you need to carry for your axe or machete, although my ceramic rod or strop block makes de-buring easy.
If I had to pick just one sharpening tool for bushcraft, I'd choose a swiss-cut axe file. My local Lee Valley sells them for $11 CAD. With light pressure I can put a pretty tight edge on a knife and strop on my belt, palm, whatever, plus I can fix an axe or machete that bent on a knot.
