Very interesting thread, really enjoyed reading it and feeling my bile rise!
Totally agree about the demonising of edges and guns by the media - really boils my pee!! I've always hated it when people say "eeeh, guns and knives are dangerous!!" - what ignorant codswallop! Its the person who picks them up that is dangerous. A biro pen can be an offensive weapon and a thing of beauty can be carved with a knife and axe. A gun or a knife are not going to jump up and start killing people on their own, and similarly they should not be blamed for the actions of stupid people as if they'd been possessed by demons the moment they touched said tools.
As for education, my three kids are more than used to seeing my rifles and edge tools around the house and know enough about them to not play with them. If you hide things away and say "don't touch!" it just makes them exotic and desirable for the wrong reasons. In the same vein - I work on a farm-based school and regularly use fixed blade knives, folding saws and air rifles there with the young people. The bosses take on it is "make it educational, hide it when Ofsted come in!" A fair and valid point - people are impressed when I say I teach young people to drive tractors with 3 foot bale spikes on but are horrified when I say I teach them to responsibly use knives and guns in a safe environment.
