If the attacker resists an Aikido technique, something will break or permanent damage will result. One of the characteristics of Aikido is that students do not train in techniques of attack. All techniques are defensive. As a result Aikido practitioners are not taught to punch, kick, or use weapons for attack purposes. Weapons practice is an important part of Aikido.
Aikido practitioners study a variety of weapons including jo, bo, boken, and katana.
Aikido is not taught through the use of kata in the traditional sense. Rather, from the beginning, students work in pairs. One student attacks and the other responds with an appropriate defensive technique. The Sensei at the Ronin Bushido Karate Club is Mr. Ronald G. Boyd who has studied Aikido for many years in the United States, Hawaii, and Japan. Sensei Boyd has studied a number of other martial arts as well.
