Is a full-tang wakizashi more valuable as a collectible than a partial-tang one?
Updated Mar 2026
From a collector's standpoint, full-tang construction signals higher manufacturing intent and structural integrity. The tang — the portion of the steel that extends into the handle — determines how securely the blade is anchored to the tsuka. A full tang runs the entire length of the handle and is typically secured with one or more mekugi (bamboo or metal pegs), replicating the construction standards of historically significant blades. Partial or rat-tail tangs are more common in lower-tier decorative pieces and are generally considered less desirable among knowledgeable collectors. When evaluating a wakizashi for long-term display or collection value, full-tang construction is one of the first specifications worth confirming.
