i seem to have broken my pencil. it is a model 1.22hb (the one with the black top) it has worked perfectly since i bought it. it did start dragging a litttle before it completely broke. There was a sharp point at the lower end which over time has become less sharp and considerably shorter. At first i thought it may need a longer charge, but cannot find any battery supplier for this model. Can anyone help..please
