Han Dao, appeared around 100 BC, was the grandfather of all Chinese Dao and its classic design became a standard for the next 800 years.
Han Dao was created to address the existential threat from Northern tribesman who were expert horseman. Leveraging the industrial might and advanced metallurgy technology at the time, Han Dao with its thick spine and razor sharp blade was a superior weapon on the battle field.
Han Dao was used by both the infantry and the calvary in the tens of thousands. One Han Dynasty arsenal recorded 156,135 Dao in storage.

Fit and finish
We perfected the fit and finish of our swords and the assembly is meticulously performed by our senior craft masters. It takes one whole working day for a craftsman to assemble our swords.
LK Chen recreates blade geometry based on antique specimens and each period sword has their unique blade profile reflecting the technology and combat requirements of their historic time period.
Void of any ornamentation and yet so subtly beautiful. So light (480 g) and yet so powerful when you yield it. From the middle of the blade, there is a subtle inward curve, creating a slight hump at mid spine and by the tip of the blade, there is another subtle reverse curve like a bird raising its head. The surface of the blade has a ever so slight groove on both sides, reducing the weight without compromising total strength and yet creating a delicate play of reflected light.
