Firesteels. My oldest got into paracord bracelets, so I figured I'd not go that route until he's out of the house. When possible, I roll my own rounds.
It's not gear, but I also make my own jerky and sausage, and I have never paid someone to butcher a single deer I've killed. Same principle: I figure I can do just as good a job or better than someone else so why pay them 100 bucks a job?
SF45ACP on the other hand not only rolls his own rounds, but he's gotten into making his own bows, arrows, and has begun dabbling in knapping his own broadheads. I'll brag for him since he's not around much
MB, I'd love to see pics of the sling. That's something I'd be interested to learn how to make.
I've thought about kydex bending. I realize it's not TOO hars once you've got the set up, but there's the initial investment of time, resources, and time...Maybe when I get to the point where I can't go out to the field anymore I'll take that up to stay connected
