Determining whether a tachi or katana is "better" depends on various factors, including personal preference, intended use, cultural context, and individual skill. Both the tachi and katana have their own unique characteristics and advantages. Here are some points to consider:

Tachi:

• Mounted Combat: The tachi was designed specifically for mounted combat, making it well-suited for slashing attacks from horseback. If your primary interest is mounted combat or studying historical mounted martial arts, the tachi may be more suitable.
• Symbolism and Tradition: The tachi holds a rich cultural and historical significance, representing the samurai class and their code of conduct. If you have a strong interest in the symbolism and traditions associated with the samurai and their weaponry, the tachi may appeal to you.

Katana:

• Versatility: The katana is a versatile weapon that was used by samurai in various combat scenarios, both on foot and horseback. It allows for a wide range of techniques and can be effective in different fighting styles and situations.
• Cutting Performance: The katana is renowned for its exceptional cutting ability. Its curved blade and sharp edge make it highly effective at delivering powerful and precise cuts.
• Popularity and Availability: The katana is more well-known and widely available compared to the tachi. There is a larger community of practitioners, instructors, and resources dedicated to the study and practice of the katana.

Ultimately, the "better" sword depends on your specific interests, goals, and preferences. It's important to consider factors such as historical context, cultural significance, intended use, and individual affinity. If possible, experiencing both the tachi and katana firsthand through training or study can help you determine which sword resonates with you personally.
