Does a firesteel rod have any abrasive qualities? Wondering if it could be used as a sharpener.
I'm in the camp that says if you have a decent knife, it is kept reasonably sharp, and you watch what you use your knife on, then you shouldn't really need to EDC a sharpener. Still, it would seem that carrying some fine sandpaper would be about as compact and useful as anyting I can think of - for the short term.
Then again, I'm finding myself to be a relative minimalist when when it comes to EDC and even when it comes to a survival kit ... more in line with Peter Kummerfeldt's philosophy. Here is Peter's site
