If you make cases and make hooks the way I used to, by using thin brass foil to stamp and original into, then back fill it with solder. You know it takes time and while they look great, they can be flimsy.
I looked at having someone laser cut them for me and they could for $10 each, minimum order 500. So we invested in some new equipment so we can make them ourselves. We now make solid brass hooks 0.025 thick. These hooks are as strong as an original hook. $1 each, 25x for $20
