With all respect COOP I have to contradict you and show some 70 years old punches which I still use on very hard metals and work like new.
FIRST: The Wexler phot show an engraver working to engrave and not to punch an MM. Punch an MM will be never perform on the engraving ball which move very easy and will not be stable for the punching.
SECOND: The Dies are hardened only before go to striking presses. Never before.
THIRD: The punches are from 80% fine steel and 20% Silver. and will never broke or chip like the working Dies. Who come with this Myth it is just pure high imagination and not facts
Sorry but we have to recognize what it is and how the things work and goes.
I do not exclude a Die chip in this case, like I do not exclude also an RPM. VV do not show to much in detail of the MM. They find many for this year and is hard to find without a compare tables.
