i would think that the knife throwing would be a no no... as a former scout and leader; a knife is a tool and should never be abused in this way.Ie which of the following is not allowed:
using a fixed blade knife or paintballing or knife throwing.
a knife belongs in either 2 places: in the hand(while being used), or in its' sheath. anything else leads way to either loss or injury.
i fixed blade knife is one of the best tools for bushcraft(no bowie knives please), and i believe it is safer than an axe(easier to control). when i was a leader, the fixed blade was only allowed after training, and demonstration of the scout in its' safe and proper use.
when parents asked me what kind of knife, i recommended a frost mora. blaze orange is best, to prevent loss in the bush.
