So just to clarify then, that's true for your classes. Not true for every style of karate, or even every school in your style. plenty of places look at kata as nothing more than a warm up or cooldown exerciseTo answer your question I was thinking the aspect what's how much risk are you willing to take if the weapon is used against you was my concern not that people will actually throw away their weapon I currently have a black belt in Karate it seems in every class they want you to practice the kata before doing the self defense moves
