Unlike the katana’s sweeping curve, the tanto can be almost straight or only gently arched, allowing samurai to slip it through armor gaps or conceal it inside the kimono as a futokoro-gatana (“stomach sword”).
A Blade Older Than the Katana
Heian Period (794-1185): Proto-tanto emerge beside the long tachi, serving as sidearms for horse-archers.

Kamakura “Golden Age” (1185-1333): Masters such as Saburō Kunimune popularize exquisite kanmuri-otoshi profiles, thinning the spine toward the kissaki for weight savings without sacrificing rigidity.
Muromachi to Edo: With battlefield tactics shifting, the katana–wakizashi pair steals the spotlight, yet the tanto finds new life in court ceremonies and bridal trousseaus, symbolizing loyalty and self-discipline.
Ritual & Legend
The tanto's razor edge is inseparable from samurai honor codes:
Seppuku (Harakiri): Warriors performed a controlled abdominal cut with a tanto to atone for disgrace.
Jigai: Female onna-bugeisha used modified blades for swift neck incisions, preserving family honor.
Pop-culture icons: From stealth takedowns in Ghost of Tsushima to Splinter’s backup blade in TMNT, the tanto stands for silent resolve.
