Ines Any kind of overly tight clothing can cause injury. Unless a steel sheet waistband is perfectly fitted (which won’t be the case if the wearer gains/loses weight) then it can be more dangerous than a cable that is flexible and adjustable. A broad fabric strap would be even better.
Anyway, to go back to the original point: chastity belts are, worryingly, still a cottage industry where the major manufacturers are one-man-operations that can abruptly close shop whenever that one artisan runs into personal problems. This is what happened to William Jones, Paul Tooker and Richard Davies, and thus the Anglo belt-makers all crashed out and ceded the market to the Germans. 😆
The only way to avoid this is to scale up. It can’t be done insisting on handmaking >€600 belts built like bank vaults, but by making some clever compromises to get a lower-cost, mass-manufacturable design that’s good enough for most use cases.
