Ninjas used many different tools and weapons to get the job done. They used
throwing stars, bows, and acid-spurting tubes to name a few. But the favorite
weapon of most ninjas may have been the katana. The katana is a long, curved
sword with a single blade and a long grip to accommodate two hands. This sword
was often carried in a sheath or scabbard on the ninja's back. Though the sword
was primarily used for fighting and killing, the scabbard served other purposes
too. The ninja could remove the sword, angle the scabbard against a wall, and use it
to climb to a higher place. Or, while stealthy negotiating their way through a dark
place (such as an enemy's residence at night), ninjas may have used the scabbard
as a walking stick, feeling or probing their way around objects so as not to knock
into anything and alert the enemy. Perhaps the ninja's most sinister use of the
scabbard was to put a mixture of red pepper, dirt, and iron shavings at the top of
the scabbard. Then, when the ninja drew his sword, his opponent would be blinded.
I wonder what a ninja could have done with a Swiss Army knife.
