[Samurai]

Unless the class is particularly reputable, I do not recommend a course at a shooting establishment to teach you knife defense. They often include one or two good techniques, but tend not to be very comprehensive. To anyone wishing to supplement their CCW training with some basics in knife defense, I would recommend a martial arts class that trains in empty-hand redirection. Examples are Aikido, Hapkido, and some forms of Jujitsu. If anyone is lucky enough to live near a reputable instructor in Krav Maga, you should definitely take advantage of that training opportunity, as Krav Maga is geared specifically toward military-style combative confrontations.

Other than that, the reality of knife-defense is that it is a practice in presenting non-vital target areas to the knife, and running like the dickens! When fighting empty-hand against a knife, the primary goal is to control the weapon. However, when fighting from CCW against a knife, the primary goal is to get FAR away from the knife and engage the target with your gun. Use your added range to your advantage!
