@hazozita, Well that's good to know. My worry was that as it dulled, it would flatten the carto out more. Seems like yours is hanging in there!
When you think about how much more a prepunched carto costs and how cheap these piercing valves are, we are probably recouping the cost of the valve after 5-10 cartos.
