you guys sound like a bunch of soccer moms that disagree and don't understand why somebody needs to carry a knife. A knife is just a cutting tool, If you work in construction or any type of labor it's useful to carry a cutting tool and use other tools.
do you guys also disagree and not understand why anybody would carry a wrench and other tools in their vehicle ?, you are just socially engineered to think that carrying a knife is unacceptable and that it's a weapon and dangerous.
