SimonM, sounds like a good system. Bit of a resurrected thread but for what it's worth:
In our Troop, on each camp we run an axe, knife and saw session for all newbies. In the Scout's record books, Skip (Nigel) adds to the inside of the back cover a check sheet for Camp skills. As a Scout is trained up in each area the sheet is signed off by the Leader who ran the training. So far we have not had to put a sharps ban on a Scout, but that is the threat. Whilst none of the training is standardised, it does seem to be working. I have a few Frost Vikings and Nigel has a few Opinels for the use of Scouts, generally under supervision. The Scouts may bring their own knives to camp where they are stored by the Leaders and released when they are needed, although I suspect that not all knives are coming back when they're finished with (I was that age once and wouldn't have liked the current rules) It is my opinion that if they are off collecting wood then a saw is the most use to them, any axe and knife work should be done back at camp, so there is no reason for them to wander of into the woods with knives. I also have a nasty habit of 'appearing' in the woods, usually when someone is about to do something they shouldn't.
I think that demonstration, practice under supervision and experience gives a good fundamental education in the safe use of cutting tools. Whilst I have a resharpening marathon after every camp, the Scouts are going home in one piece. I hope to bring up the standard of care of the tools, but keeping the youngsters intact is the first priority.
I was taught mainly by pain and blood loss. Whilst effective I don't think that that is the best way but I really don't want to see a generation growing up with no idea how to handle traditional Scouting tools. I've dealt with a few cuts from sharps use on camp. At that age they heal quickly and bounce back fine. It is always a learning experience and the Parents all seem to be happy with their Sons and Daughters going out and doing.
All the best, lets keep fighting the boredom-mongers.
