why do you carry a knife?

[Larryjk]

I have carried a "Old Timer" three blade pocket knife all my life. There was almost every day it was needed to cut something. I can remember the teacher asking me to borrow my pocket knifel to cut something. This is about a 3 1/2 inch model. My son now carries one but not as religiously because he was prohibited by the school system in his "formative years". Now he hates to ask me for mine if he has forgotten his. However, if someone was to come at me with a knife, I would shoot them without warning.
