The   word   Kobudo   describes   a   Martial   Arts   fighting   system   which   mainly use   tools   as   weapons.   The   word   itself   is   build   from   the   word   Ko   (little,   or old),   Bu   (short   form   of   Bushi,   what   means   warrior)   and   Do   (way   or   art). So   it   can   be   translated   with   the   little   or   small   Art   of   war.   Small   or   little because   the   weapons   are   not   especially   constructed   for   war.   In   fact some of them (Tonfa/Kama) are tools for farmer. So   the   Bo,   as   the   most   famous   Kobudo   weapon,   was   for   wandering   or for to carry something on the back. Though    the    Kobudo    is    focused    to    use    weapons,    of    course    some weaponless techniques are included. So   at   least   we   can   understand   Kobudo   as   a   Martial   Art   which   includes everything what is usuable as a weapon, equal if it is a hammer or a fist.
