What does full-tang construction mean in a Japanese sword?
Updated Feb 2026
Full-tang means the blade steel extends as a continuous piece through the entire length of the handle, from the cutting tip to the kashira (pommel cap). The portion of steel inside the handle is called the nakago, and it is held in place by one or two bamboo pins (mekugi) that pass through aligned holes in the tang and the wooden handle core. This is the traditional construction method used in authentic Japanese sword making and is considered the strongest structural approach. The alternative — rat-tail tang or welded tang — involves a thin metal rod attached to the blade base, which is far less durable and can loosen or break under stress. Every sword in our collection uses full-tang construction.
