I have an older razor that I picked up a while back and during the process of restoration, I managed to break the tip off of one of the scales right through the pin hole. I have tried a variety of glues and epoxy in order to avoid making new scales but whenever I go to pin it again, it always cracks. The scales seem to be regular black acrylic, what should I be using to attempt this? Or should I just save what I have for future restorations and make some new scales for this one?
