Great work @enforcer48. I can't imagine the time and effort put into producing the bottle openers. I kind of have the experience of working in a mechanical workshop when I was studying Electrical and Electronics Engineering at a Federal Polytechnic here in Nigeria. We had a mechanical course in which we had practicals and one of the practicals was working in the workshop in producing a bottle opener which some also did a key holder. It was fun and at the same time very challenging. We had to do lots of hard work to finally produce the bottle opener.
