I still have a store-bought case (not wood) that my brother and I bought for our parents many years ago. It held most of the things you have in yours except a cutting board. My parents took it to every party they went to.
That is a wonderful job you did with this Dave! Absolutely stunning!
It looks like you used oil tanned leather, if so, don't worry about it breaking, it looks substantial to me. Just make sure the pins don't fall out.
