Why Use Traditional Pivot Pins Anymore?

[TheLegalRazor]

Last year I had Max replace the pivot pin on a razor with one of his adjustable ones. I also got a Hart Steel razor with its hex nut pivot pin. Loose pivot pins have always annoyed me. I've done the tapping routine with the ball peen hammer numerous times. The pins tighten but eventually get loose again. Other than restoring a vintage razor, why use traditional pins anymore?

Most of the custom makers are using hex nuts for pivot pins. The Robert Williams SRP LE razor has a hex nut. There is now one Dovo model that I'm aware of that uses a hex nut. The advantages seem obvious to me. Are we continuing to use traditional pivot pins just because that's the way it was always done?
