Kodachi

Kodachi is a term with more than one notable meaning. In traditional Japanese weaponry, kodachi, meaning “little sword,” refers to a short blade used by samurai as a companion weapon or for close-quarters combat. The blade length is typically shorter than a katana, commonly described as around 40 to 60 centimeters, and it could be worn as part of a daisho with a longer sword. Variants exist with curved or straight blades, and historical variations in grip and fittings reflect different schools and periods.

In martial arts practice, kodachi can be used in a variety of ways, including single-handed techniques or paired forms that complement longer swords. Practice and interpretation of kodachi usage vary between schools, and while it is less common in modern training than longer swords, it remains a part of historical study and some composite sword systems.

Kodachi also refers to Kodachi Linux, a privacy-focused Linux distribution designed for secure and anonymous computing. It ships with a suite of privacy tools preinstalled, including the Tor network and a VPN, DNS leak protection, and configurations aimed at minimizing traces. The system is typically used from removable media and emphasizes a portable, privacy-aware environment for users who require enhanced anonymity. As with any security-focused tool, users should understand its capabilities and limitations and keep the software updated.
