Pleasingly, this isn't too unique i don't think - my kids have an afternoon called 'bushcraft' timetabled in each week at their school. Lots of fires, knife work, foraging etc (no axes yet though i think). Plenty of other schools seem to have significantly bought into the whole Forest Schools thing in recent years in addition (although to be fair, at my kids last school, that involved sitting under the only tree on the school premises and using a wax crayon to do a leaf rubbing!)
