Chipping Hammer Time

I had no idea there was something at hardware store that I didn't know it's use for.  This odd springy peg head screwdriver is actually a chipping hammer.  The nicely employed lady Peggy helped me see in a book nearby that it's use was for removing the slag from arc welds.  Apparently, when finished welding there exists imperfections that can be easily and quickly removed by this hammer.  It's spring handle absorbs shock and cuts down on heat. There are two heads that each are used differently for striking.  When the Peggy showed me she also told me how she worked for a furniture plant and their welds had to be ultra-clean.  She described to me how they'd chip with this hammer first and then use various abrasive tools that would almost completely hide a weld.
