Knife fighting is a form of combat that involves the use of a knife as a weapon. It can be practiced in various martial arts and self-defense systems, where practitioners learn techniques for both attacking and defending against knife attacks. The focus is often on speed, precision, and the ability to control distance between opponents. Training in knife fighting typically includes drills, sparring, and the study of different styles, such as Filipino Martial Arts or Kali. Safety gear is often used during practice to minimize injuries, as knife fighting can be dangerous and requires a high level of skill and awareness.
