Higonokami

Within the Taihō Code, Kami (長官) was the highest of four titles of shitōkan (四等官) in the "four-ranked officials" system, the others being suke (次官), jō (判官), and sakan (主典).

Kami can be spelled in numerous ways depending on the government agency; in the case of the Kokushi (国司, "Governor's Office"), the kanji is 守 which means "protector".

The knife first appeared in 1896 as a result of smiths and metal workers struggling in post-samurai Japan following the major reform of the country made by Emperor Meiji in the late 19th century.

With the abolition of the samurai class, the decline in demand for swords, especially after wearing them in public became illegal in 1876, required diversification into tools and knives.

But sales went into decline after harsher knife legislation was enacted in Japan in 1961 following the fatal stabbing of Japanese politician Inejirō Asanuma as well as the attempt on then Prime Minister Nobusuke Kishi a year earlier, both by far-right activists.
