I'd like to ask a related question.  How are people sharpening these
wires?  I keep borrowing an apparatus from someone down the hall, which
incoporates a direct current power source, eletrical connections to the
tungsten wire, and to a ground, and a saturated sodium nitrate (I think)
solution as the corrosive buffer.  But I find that to be so inconvenient. 
Is there a better way?
