Is a full-tang katana better for display than a partial-tang version?
Updated Mar 2026
For display and long-term collection purposes, full-tang construction is strongly preferred. A full-tang blade extends the steel through the entire length of the handle, secured by one or more mekugi (bamboo or brass retaining pegs). This creates a mechanically stable assembly where the handle does not loosen over time from its own weight or minor handling during cleaning and inspection. Partial-tang designs, where the steel extends only partway into the handle, are more prone to developing play at the handle joint as adhesives age. For a mounted display piece that will be taken down, examined, and repositioned over years, full-tang construction ensures the katana retains its original fit and alignment - which matters both aesthetically and as a mark of long-term quality.
