Charlie (Spazola) does some really nice work! I know that both Mike Blue and I were quite taken with his design, workmanship, and ingenuity.
The results of the hardness tests were surprising because they said that a shaving edge can be attained at other than 58-65 HRC.
Mike also suggested an approach that will probably be useful for the both of us since we do not have a Rockwell testing machine.
