How do I confirm full-tang construction when evaluating a wakizashi?
Updated Feb 2026
Confirming full-tang construction in a wakizashi involves examining the handle for the specific features that indicate the blade steel runs through the complete handle body. The most reliable indicator is the mekugi pin: a genuine full-tang wakizashi will have one or more mekugi pins visible on the handle surface - typically small bamboo or metal cylinders pressed through holes that pass completely through the handle and the blade tang simultaneously. The pin prevents the handle from separating from the blade under stress. To identify a mekugi pin, look for a small circular feature on one or both sides of the handle body, approximately one-third to one-half of the way along the handle length from the tsuba guard. A second confirming indicator is handle weight: a full-tang handle with blade steel running through it will feel noticeably heavier than a partial-tang alternative with only a narrow rod inside. If a product description does not explicitly confirm full-tang construction with a mekugi pin, it is appropriate to verify this through the product details or customer service before purchasing. Every piece in this collection is confirmed full-tang by both the mekugi pin criterion and explicit product description.
