Rubber, wooden and aluminum training knives are the foremost types of training knives used to safely practice weapon techniques and self-defense against knife attacks. Although a solid hit, thrust or slash with any one of these types of training knife can be painful, they are relatively safe, and allow martial artists to try techniques without getting hurt.
Training knives are shaped in a variety of styles and sizes, but the main types of training knives are based on the Bowie knife, Ka-Bar knife, Tanto knife, dagger and folding knife. (The first five Academy articles about modern weapons cover these specific types of knives). The Bowie, Ka-Bar and Tanto training knives are good training substitutes for different types of Viking seaxes, and the smaller training knives are good substitutes for the basic small Viking knife.
