Great conversation guys, It's really nice to see countryman help each other out, as you know each others environment.
Marthinus, I stole this from british blades and wonder if you could explain it to me.
Potassium Permanganate for water purifying, mixed with sugar makes for a great fire lighter...
Just a tablespoon full in one of those match plastic packets will be enough...
I am really confused about mixing with sugar?
Oh and one thing I don't see (might have missed it) is a way to sharpen your blade(s).
Sorry for the late reply but I see zulu already answered the question with some good references.
As for sharpening your blades. I have 3 small sharpeners in the bag. A lansky diamond paddle (600grit) a lansky crock stick, a simple benchstone from felco and of course a steel file on the Swiss Tool. The steel file is probably used the most since I learned sharpening with a steel file on a machete.
