Sometimes simple is best.
Nuff said !!
Sometimes you have to look a little deeper. The pen developed for space was safe and left no comtaiments floating around.
The pencil had to be sharpened, which created shavings and graphite from the lead, and also was much sharper then the pen. Not a problem you say? Have you ever been stabbed with a pencil? i have, accidently, and it hurts! And can draw blood!!
