A fighting knife is a knife who blade is specifically designed to inflict injury against an opponent at an very close distance. for a martial artist it would be grappling distance. Being honest with you any knife is capable of inflicting injury against someone even a butter knife but these are dangerously sharp. even messing with the blade i cut myself very lightly. I personally love the idea of knives in combat. its a quick way to incapacitate an opponent. People seem to forget that martial arts can also include weapons. even in traditional martial arts where it mainly an visual art for sightseeing purposes and entertainment the knife is used.
