Do the letters and numbers stamped on tool parts mean something?

Hi all, I have another question.
I was just looking at my Juice SC2 because I just can't help myself.   And was wondering what the letters and numbers mean?  And are they supposed to be backward?  On the pliers there is a backward "C" on one corner and a #1 on the other.  The phillips screwdriver has B1 on it.  Just curious.  Thanks all,
Gray

I am thinking it is for assembly purposes. So the operator knows what component goes where each time. I have very familiar with some assembly process' and we do the same type of things to ensure the end product is the same each time.
