Ninjas used many different tools and weapons to get the job done: throwing stars, bows, acid-spurting tubes to name a few, but the favorite weapon of most ninjas was probably 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 a number of 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, so that when the ninja drew his sword, his opponent would be blinded. I wonder what a ninja could have done with a Swiss Army knife. Summarize the passage.
The katana was a powerful fighting sword, but the scabbard had additional uses as a climbing tool, a probing tool, and a blinding weapon.
