Should I choose a preserved nakago or a no-hole full-tang configuration?
Updated Mar 2026
The choice depends on your collecting intent. A preserved nakago blade retains the tang exactly as it left the forge — unworked, undrilled, showing the natural forge-finished surface with visible hammer marks and original oxidation. This configuration is prized by collectors focused on historical authenticity and documentary value; it presents the blade as a study object, complete in itself, typically displayed in a shirasaya or on a stand. A no-hole full-tang configuration, by contrast, gives custom assemblers a clean starting point: the tang is finished and structurally sound, but without pre-drilled mekugi-ana holes, so you can position your own handle fittings precisely. If your goal is pure display and study, preserved nakago. If you are planning a DIY koshirae assembly with custom tsuka, no-hole full-tang is the practical choice.
