The Firmament Tachi | T10 Maru No-Hi Gunome Hamon Traditional Mounted Japanese Tachi Sword
Product Introduction
The Firmament Tachi is a historically accurate horseback-style tachi sword, distinct from regular katana with complete traditional tachi koshirae mounting system, priced at $459.99 as mid-range historical collection piece. The blade adopts T10 high-carbon maru mono steel without blood groove, processed by classic Tsuchioki clay differential tempering to form continuous natural gunome wave hamon. Full fine hand grinding is applied across the whole blade, plain uncarved surface with real yokote, fully sharpened for display and light cutting practice.
This tachi features full solid copper mounting hardware exclusive to tachi: tsuba, fuchi, kashira, menuki, seppa, habaki, koiguchi, ashikanamono, kawasakikanamono, semekanamono, ishizukikanamono and kashiwaba are all copper cast. The tsuka core is wrapped with genuine ray skin and traditional moro-hineri-maki handle wrap. Solid wood lacquered saya matches genuine cowhide taikogane tachio leather cord for waist hanging edge-down wearing, the classic tachi characteristic. Full tang disassemblable construction fixed by two bamboo mekugi pegs, easy to detach for blade maintenance. Total full weight reaches 1.85KG, desheathing weight 1.3KG, delivering heavy historical wielding texture for tachi collectors.

Frequently Asked Questions
Q: What’s the core difference between Tachi and regular Katana?
A: Tachi is worn edge-down hanging from waist via dual copper ashikanamono rings and cowhide tachio leather cord, originally designed for ancient horseback samurai; katana is tucked edge-up inside obi without hanging fittings, for foot combat.
Q: What’s the advantage of gunome wave hamon?
A: Gunome hamon forms continuous rolling wave lines along the blade edge, widely used on historical nihonto, balancing cutting sharpness and blade toughness with distinct collectible visual texture.
Q: Why this tachi has heavier total weight than regular katana?
A: Full set solid copper tachi exclusive hanging fittings add overall mass, restoring the heavy solid texture of ancient aristocratic mounted samurai tachi for historical collectors.
