The kama was improvised from a sick.le of sons, and the vast majoriry of kama in the Empire are still being used in the fields by farmers to harvest crops. However, the kama has also become the signature weapon of a great many Mantis samurai, particularly among the Yoritomo family, so it is generally regarded as a weapon even if it is perfectly acceptable for peasants to possess them.
The jitte and sai are weapons that were adapted from farming implements during the early days of the Empire, and which have slowly gained acceptance with the samurai caste since that time. The jitte in particular is an accepted symbol of a magisterial position. Both are steel cylinders roughly a foot long that possess a short handle and a blunt tip. Both possess metal prongs that originate from the divide between the handle and the blade: the jitte has one prong while the sai has two symmetrical prongs.
The aiguchi and tanto are both very simple, basic knives with few differences save that the aiguchi possesses a hilt guard and the tanto does not. Many samurai carry a tanto for grooming purposes.
