What does full-tang construction mean for a collectible wakizashi?
Updated Mar 2026
Full-tang construction means the steel of the blade extends continuously through the entire length of the handle, rather than being attached via a short stub or threaded rod. In a traditionally assembled wakizashi, the tang passes through the tsuka - the handle - and is secured by one or more mekugi, small bamboo or wooden pegs that pass through aligned holes in the handle wrap and the tang itself. This assembly method is the same used in historically authentic Japanese sword construction. For a collectible, full-tang construction signals a higher standard of craftsmanship and ensures the handle assembly maintains integrity over decades of display use. It also allows the sword to be disassembled for cleaning and inspection, which is a hallmark of genuine Japanese-style construction.
