I remember reading an article many years ago from a knife magazine where the writer interviewed some Navy Seals about their usage of knives on a mission. They all said that knives were pretty much useless on a mission. Not the response that the writer was looking for. I can’t dispute an expert on this but I think that in civilian life, I have a greater need for a knife than a Seal. I use it for countless tasks during the course of the day. I also used it once to defend myself when I had nothing else. Luckily just showing the blade and obviously being prepared to use it was enough to stop the attack. I have carried a knife since I was about 11 years old and do not feel comfortable without one in my pocket.
