The terms "kodachi" and "tanto" refer to two different types of Japanese swords, each with its own distinct characteristics and historical usage:

Kodachi:

• The term "kodachi" translates to "small sword" or "short sword" in Japanese.
• Kodachi generally refers to a sword that is shorter than a traditional katana but longer than a tanto.
• The blade length of a kodachi typically falls between 50 and 60 centimeters (approximately 20 to 24 inches), although there can be variations.
• Kodachi swords are often characterized by their slightly curved, single-edged blades.
• Historically, kodachi swords were used in specific contexts, such as by foot soldiers, samurai on horseback, or as backup weapons.
• Due to their compact size, kodachi swords were versatile and suitable for close-quarters combat, allowing for quick movements and rapid strikes.

Tanto:

• The tanto is a traditional Japanese dagger or short sword.
• Tanto blades typically have a length of less than 30 centimeters (approximately 12 inches).
• Tanto swords can have either a straight or slightly curved blade profile.
• Historically, tantos were used by samurai and non-samurai alike as a self-defense weapon, for utility purposes, and as a symbol of social status.
• Tantos were often worn together with a longer sword, such as a katana or wakizashi, as part of the samurai's daisho.
• Tantos were effective in close-quarters combat and were known for their stabbing and thrusting capabilities.

In summary, the key differences between a kodachi and a tanto lie in their size and blade length. Kodachi swords are shorter than traditional katanas but longer than tantos, typically falling within the range of 50 to 60 centimeters. Tanto swords, on the other hand, are shorter daggers with blade lengths of less than 30 centimeters. Kodachi swords were used in specific contexts and were versatile for close-quarters combat, while tantos were primarily used for self-defense, utility purposes, and as a symbol of status.
