This year at camp I taught knife throwing and people throwing. Specifically, I taught a basic knife spin throw and the basics of head control in relationship to throwing.
In terms of the knife, one of the most important parts about getting it to stick is being the proper distance away. The game, at first, simply involves stepping inches closer or further away from the target until you get the blade to stick. Once you get a knife to stick, you mark that spot and keep throwing from there.
For learning to throw people, head control is a great introductory tool. Head control means using your forehead to compromise your partner’s structure. Basically, you drive your forehead into their head at an angle that makes them lean backwards. Once you’ve got them leaning backwards, it is way easier to set up a takedown.
