How long is a Tachi sword?

A tachi is a traditional Japanese sword that was primarily used by samurai during the earlier periods of Japanese history. The tachi is characterized by its curved, single-edged blade and is typically longer and heavier than the katana.The average length of a tachi blade is around 30 to 36 inches (76 to 91 centimeters), although there can be variations depending on the specific sword and historical period. The handle (tsuka) adds additional length to the overall measurement.Compared to the katana, the tachi has a longer cutting edge and is designed to be worn with the cutting edge facing down. It was typically used as a battlefield weapon, especially on horseback, and had a slightly different construction and wearing style than the later-developed katana.It's important to note that the measurements provided are approximate and can vary between individual tachi swords due to variations in historical examples, regional traditions, and personal tastes of sword owners or collectors.In summary, the blade length of a tachi typically falls within the range of 30 to 36 inches (76 to 91 centimeters), although variations can exist. The tachi is a traditional Japanese sword that predates the katana and is known for its longer and heavier blade.

What makes 1060 carbon steel a good choice for a display katana?

1060 carbon steel sits at a practical midpoint in the carbon steel spectrum, containing approximately 0.60% carbon by weight. This composition allows it to be hardened to around 58–60 HRC during heat treatment, giving it enough structural integrity to hold a well-finished edge and resist flexing under its own weight when displayed horizontally. Unlike lower-carbon alloys, it develops a subtle surface character over time that many collectors find visually appealing. It is also easier for skilled smiths to hand-forge without the brittleness risks associated with ultra-high carbon steels, which means the blade geometry and profile are more consistently executed across individual pieces. For a collector who values knowing that their display piece is grounded in real metallurgical tradition rather than purely decorative construction, 1060 is a highly credible foundation.

What makes a tachi different from a katana?

Updated Feb 2026

The tachi predates the katana by roughly three to four centuries and was the standard long sword of the mounted samurai during the Heian through Muromachi periods. The most immediate structural difference is curvature: a tachi typically carries a deeper sori (arc) measured from the base of the blade, which suited the geometry of drawing from horseback. Equally important is how each sword was worn — the tachi was suspended edge-downward (ha-sage) from the obi using cords called ashi, while the later katana was thrust through the belt edge-upward (ha-mune). Blade length also trends longer on the tachi, commonly exceeding 70 cm. On a correctly made tachi, the mei (smith's signature on the tang) is placed so it faces outward when the sword is worn in the traditional ha-sage position, which is a reliable authentication detail collectors use to distinguish a true tachi configuration from a re-purposed katana blank.
