This is the part of the hobby so many shooters are missing out on. It's rewarding to make your own "possibles" and then use them.
I think so many shooters believe they do not have the skills to make these simple items perfectly. They miss the point that this isn't about perfection. It's about functional. Long Hunters and mountain men weren't into worrying about perfect. It just had to work. And if it didn't work as they wanted, they would just redo it. No big deal.
