Rolled tips have been used in practice and tournaments since at least 2008, and have seen hundreds of thousand of hours of use. The reality of the situation is breaks or safety situations, are in the 0.00000001% range. A rolled tip does have the potential to break sharply, I've seen a few, and heard of a few people getting scratched. Maybe even 1 or 2 stitches. I don't know of any Regenyei rolled tips that have broken. Maybe they have, but I have no record of it. Europe seems to not have any issues and use rolled tips all the time. In the USA, much has been said for a push to use spatulated tips and we are moving most of the VB line to spatulated tips because of it. The thrusting impact surface area of a rolled tip is greater than a thin/wide spatuated tip. I've heard about them penetrate gloves, hands, and jackets as well. Most swords, when they do break, its usually 6" down from the tip. Its typically a straight break, and mostly no issue, but a disheartening twing.
Regenyei doesn't make spatulated tips and they say their safety record speaks for itself. Based on my design recommendations VB has been moving to spatulated tips from 2022 onward.
