Test program:
The pencil should be planed, and the graphite about 5mm can be used to meet this requirement with special pencil planer including special scope within the scope of supply.Hold the pencil vertically and the graphite facing down on the sandpaper (with a fine size of 400 particles) flattening the graphite core and the edges sharp.
