My ditty bag, which also serves as my EDC survival kit and lives in my handbag, at this very moment weighs 14.8 ounces, and yes, it contains a large ferrocerium rod, as well as a diamond-coated steel credit card-sized DiaSharp sharpening stone. Will I likely need these in my small town, if I were forced to walk the 2 miles from my office to my home, even in Winter? Probably not, but my handbag isn't onerous to carry.
