I carry one of several folding knives every day. I also sometimes carry a small (~2.25" blade) belt knife in a horizontal sheath near mid0line up front. The draw stroke is toward the mid-line with either hand. For strong hand it comes out with the blade forward (down on the belt) at the heel of the hand. For weak hand it is a typical knife grip. The idea is to be able to produce the knife if your arms are essentially pinned and use it immediately to help get out of the pin, do damage to the attacker and, if possible, then make distance. We work these skills periodically at the training academy I attend.
Stay aware and engaged. Awareness buys time; time buys options. Survival may require moving quickly past the Observe, Orient and Decide steps to ACT.
