Should you use edged weapons for self defense?

As stated in the title, I pose a question to you. Should you use an edged weapon during a self defense situation? Is it really advantageous for you to carry a blade for self defense purposes? This is a question I would like you to answer for yourself, But I will share with you my personal opinions on the matter.
Here are some follow up questions I would like you to ask yourself as you assess this decision.
- do you know how to effectively use a blade for self defense? do
- do do you regularly train to use my blade for self defense?
- do you regularly visit places where blades are allowed to be carried?
- do you understand the subjective implications of carrying a blade for self defense?
Think about it. It could mean the difference between life and death, and prison or no prison time.
