Thanks. That is what I was thinking. I couldn't find anything either. Was just wondering about it because my 13yo has carried a knife (while with me) for years. We used to say that he couldn't do it in Denver- he already knows they are d-heads about guns so he accepted it. Now that he is a bit older, I wanted to find out the actual legal reality. They are great tools. My grandfather always carried a knife and I picked it up from him.
