passage: Many martial arts employ the use of common objects as weapons; Filipino martial arts such as Eskrima include practice with machetes, canes, bamboo spears, and knives as a result of the 333 year Spanish colonization that took place in the Philippines which prohibited the ownership and use of standard swords and bladed weapons; Chinese martial arts and some Korean martial arts commonly feature the use of improvised weapons such as fans, hammers and staves. There are even some western martial arts that are based on improvised weapons such as British quarterstaff fighting and Irish stick fighting.
