Just a thought...
During the Meiji era (1868–1912) and early Taisho era (1912–1926), kendo was still evolving, and practitioners often used equipment that blended traditional and modern elements. Some kendo masters, particularly those who were deeply rooted in classical kenjutsu traditions, might have preferred the feel and symbolism of an iron tsuba, even if it was heavier and less practical than the lightweight tsuba used today.
Possible Context:
Transition from Kenjutsu to Kendo: Early kendo masters who were trained in classical swordsmanship might have modified iron tsuba for use on shinai to maintain a connection to the traditional samurai aesthetic and training methods.
Personal Preference: Some masters might have valued the durability and historical significance of an iron tsuba, even if it was unconventional for kendo.
Gekiken Competitions: Before kendo was fully standardized, gekiken competitions were more rugged and less regulated. An iron tsuba might have been used in these early sparring matches, though it would have been risky due to its weight and hardness.
Notable Figures:
While there’s no widely documented case of a specific kendo master using an iron tsuba, some early kendo pioneers who might have been associated with such practices include:
Takano Sasaburo (1862–1950): A key figure in the modernization of kendo, he was deeply knowledgeable about classical kenjutsu and might have experimented with traditional equipment.
Naito Takaharu (1862–1929): Another influential kendo master who helped standardize modern kendo but had roots in classical swordsmanship.
