What is Takehikari in Japanese Katana terminology?

"Takehikari" (竹光) refers to a sword blade made by carving bamboo. During the Edo period, it was used by samurai and others who sold their sword blades due to economic circumstances. The term ""Hikari"" (光) is derived from the names of famous swordsmiths from the Kamakura period, such as ""Nagamitsu"" (長光) and ""Kagemitsu"" (景光). It should be noted that wooden sword blades, which were used in place of real sword blades for the appreciation of sword fittings (Koshirae), are referred to as ""Tsunagi"".

This practice reflects the economic realities of the samurai class during the Edo period. The use of bamboo as a substitute for a real sword blade would have been a practical solution for those who could not afford a real sword. The derivation of the term ""Hikari"" from the names of famous swordsmiths adds a touch of prestige and historical significance. The use of wooden sword blades for the appreciation of sword fittings underscores the importance placed on the aesthetic aspects of sword making."
