Maybe because, aside from it's name, it was a knife. It had a knife blade.
The real crime is the idiot Scout-Master that was handing out Coleman Hobo Tools. Those things SUCK!. Smart move anyway, at that age would have been to go with the split-style camping tools where the knife blade attaches to the fork and spoon but can be seperated when needed.
If it is the same style of tool that I had in Cub Scouts than the so called "knife" couldn't cut through any skin.
Look at the pic, it's a Coleman; or a Coleman knock made for the Scouts-- despite what people think Scout kit is actually pretty shitty at time.(1) Crappy construction (scales are utter shit on those things, and the stainless they for the untensils is just flat out bad metal) aside, the blade is pretty damn sharp-- not much use as a camping tool if it wasn't. When I was in scouts and the knives were issued, they were dull but our first "lesson" was in sharpening them. I've no doubt that the blade was sharp.
I'm not saying the kid should be expelled or sent to a reform school. A few days in-school suspension, sure. I seriously doubt that he's the next Charlie Manson in a cubbie uniform. I'm saying don't play the incident off as if some kid got popped for carrying a Spork. He had a pocket knife, an item that fell within the scope of the Zero Tolerance policy; calling it by a different name doesn't change what it is. He exercised poor judgment (he's six, so no duh on that point), hopefully being in scouts will teach him about taking responsibility for your actions.
As I said in sub-forum that shall not be named. Some of the blame in on mom and dad too for not keeping up with what their kid is and isn't taking to school.
(1 - I've the same model knife that I got from, you use it, a Boy Scouts supplier that was selling them off. )
