So I'm looking for the most versatile sharpener which I can add to a camping pack or BOB or the like. What are some suggestions? My initial inclination is to a DMT diafold. I have had excellent experiences with their bench stones so its a natural move. The main hold up is determining which grit to choose. I like the green xfine finish, but I like the versatility of the blue/red (coarse/fine) combo. Further, I have been using the Spyderco Sharpmarker as my EDC maintenance for many years now with perfect results so maybe a ceramic option exists that would be better?
