Those old brass split binder rivets for holding punched paper together? Probably too wide..,
No, they do work. I've used brass split pins. The only problem is the more you bend them the weaker the brass becomes and eventually they break. They're also very light weight and don't dry out the cymbal like a heavier rivet would, but they're useful substitute. I actually asked in not one, but two of my local hardware store and they had none. Unbelievable! I should probably be looking in a stationery store for those?
