Each Cold Steel Training Knife has been carefully fashioned to look as realistic as possible so they can be effectively used in Airsoft Skirmishes, solo practice, training drills, disarm drills, and demonstrations and any other activity where you want a reasonably close approximation of realism but not the extreme danger and risk associated with an actual knife. The Santoprene rubber blades are soft enough to prevent the likelihood of most bodily injury. They do however, have a level of firmness that might cause injury to the face or the eyes, so it is recommended that appropriate eye protection is utilized at all times when using a Cold Steel® rubber training knife.
