Mine is literally being held together by two rubber bands.
Suggestions for a new one would be most welcome. Though to be clear, I'm not asking for an idealised wallet, I'm asking for the specific one that you have now that has lasted you X years without complaint
The more worn and frayed, the better

You can use gaffer tape to rebuild some of the sections which have worn through.
[Edit] Though, looking at my wallet, I'm at the stage where the gaffer tape is wearing thin in places, so some of my gaffer tape needs gaffer tape.
