I like your sharpener, nice lateral thinking.
I just remembered a thing called "chemical sharpener". I got some when I first started welding -- you get the tip hot, and dip it into the chem sharp powder and an exothermic chemical reaction takes place, eroding the tip into a point. Smells terrible, and probably isn't too smart to use indoors, but if I were 30 feet up a ladder, I'd use it.
