IMHO, the attributes of a "fighting knife" are not mutually exclusive with the attributes of a good utility knife.

I found that even the one-dimensional, tanto edged folder that I have been EDC'ing the past several weeks has been exceptional at everyday task both in the field and at home.

I am not in the service nor in law enforcement, yet my requirements for a reliable folder often lead me to look at knives that were designed with those purposes in mind. While not specifically looking for a "fighting knife", when I look for a robust, easily opened lock and a durable edge geometry, I often find myself looking at one.
