I've got a leather wallet designed to hold my keys and the metalwork that h olds the keys is shown on this photo:
I've had it for about 30 years and in that time I have replaced the leather part as it wore out.
The point is that the metal bit with the clips that hold the keys is design ed in a way that's very strong and long-lasting with a pin going through th e clips. All the ones I have found online and in shops have a very poor des ign where it looks to me like it'd wear out in a year or two and fall apart - like this one:
Anyone know where I can get one like mine?
