Frequently Asked Questions

What is a T10 tachi sword?

A T10 tachi is a traditional Japanese sword forged from T10 tool steel and designed in the classic tachi style. Unlike a katana, a tachi typically features a deeper curve and was historically worn edge-down while suspended from the belt by mounted samurai. T10 steel is valued for its ability to achieve excellent hardness and produce an attractive hamon when clay tempered. A handcrafted T10 tachi combines historical design with modern forging techniques, making it a popular choice for collectors, martial arts enthusiasts, and anyone who appreciates traditional Japanese craftsmanship.

Is a T10 tachi full tang?

Yes. All swords offered by TrueKatana feature a full tang construction. A full tang means the blade extends through the entire handle, providing superior balance, structural integrity, and long-term durability. This construction is preferred for handcrafted swords because it creates a stronger connection between the blade and handle than partial tang designs. When comparing different T10 tachi models, you should also evaluate the heat treatment, fittings, craftsmanship, and overall design to find the sword that best suits your collection.

What is the difference between T10 steel and 1095 steel?

Both T10 steel and 1095 steel are premium choices for Japanese swords, but they offer slightly different characteristics. T10 steel contains additional alloying elements, including tungsten, which improve wear resistance and help produce excellent cutting performance when properly heat treated. 1095 steel is valued for its high carbon content, exceptional hardness, and impressive edge retention. Both steels are capable of producing beautiful hamon patterns through clay tempering. In practice, the quality of the forging and heat treatment often has a greater impact on performance than the steel designation alone.

Are T10 tachi swords legal in the United States?

In many parts of the United States, owning a traditional Japanese tachi is legal. However, regulations governing transportation, public carry, and display vary depending on state and local laws. Before purchasing a T10 tachi, review the regulations that apply in your area. If you plan to bring the sword to a convention, historical event, or public exhibition, always check the organizer's official policies, as many venues prohibit metal swords regardless of local laws.
