i do primitive fire stuff, bow drills, hand drills, etc. Also some traps. Never tried weapons, mostly cause I taught primitive skills to teenage boys with serious mental health problems as a means of therapy and for obvious reasons I didnt want them knowing how to build bows or knap flint. I've always wanted to make an atlatl. There are pretty good directions on the internet. Can't be too hard if cave men did it.
Making shelter and fire always seemed the most important to me and thats where I've put my dirt time, even though it's not the racy stuff. As an example of whats possible: I walked out on a three day hike in Yellowstone a couple years ago, picked up three good sticks and a knee bone from something like an elk, added some parachute cord, whittled it all up and had a fire in 15 minutes or so. Didn't use a lighter that trip. (And now, for bragging, the fire gods will make me spend at least one night someplace cold, wet, dark and lonely.) :]
If you want instant gratification, google 'fire piston' to see what we would be using instead of chemical tipped matches. I have one. It works like a diesel engine and it's incredibly easy and simple. Best fire toy ever and a great addition to a survival kit.
