I do carry a small pencil sharpener in one of my fire-starting kits. The shavings made from just about any reasonably dry wood catch very easily, but I often nest them around a PJ-soaked cotton ball just to be sure of things. The only down side of shavings is they must be completely shielded from wind - they scatter on the slightest breeze.
