, US Forces issue Throughout history, common tools were used so often as weapons in self-defense that many of them evolved specifically into weapons or were adapted with the secondary purpose of being used in self-defense, usually by adding modifications to its design. Well-known examples include the Irish
shillelagh, which was originally used as a
walking stick; the Japanese
bō, which may have originally been used to carry buckets and baskets; and the Buddhist
monk's spade, a shovel monks used for burying corpses, which often had sharpened edges to help defend against
bandits. Many
martial arts use 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 in the
Philippines that 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. After the
German Peasants' Wars during 1524 and 1525, a 1542 fencing book edited by
Paulus Hector Mair described fencing techniques using a
scythe. ==Legal issues==
