Yes, each Zenitsu Agatsuma replica features full-tang construction, meaning the steel extends the entire length of the handle rather than being a partial insert. This design is rooted in traditional Japanese sword-making and ensures the blade, tsuba, and tsuka function as a single balanced unit. For collectors, full-tang construction translates to a more authentic weight distribution and a solid feel when the sword is picked up or repositioned on a display stand. The tang is secured through the handle with a mekugi pin, following the same assembly method used in traditionally crafted katana.
