Ball and Chain
When Mark goes to Summer camp, inevitably the scouts start carving. And they carve, what else, spears. So to help them see that other more interesting things can be carved, I usually carve a Ball and Wooden Chain tool.
It's described as a 'Scout Behavior Improvement' device.
I carve it while hanging around the natural places that scouts hang at when they should be going to their Merit Badge classes. Random scouts stop by and admire the work, and I get to talk to them about how's it going and what are you working on and shouldn't you be at class right now. By the end of camp, I have a bunch of regulars that check in to see the progress.
I always give it away at the following Court of Honor to the Scout I feel has shown true Scout Spirit at camp.
