The majority of the tanto pieces in this collection use full-tang construction, meaning the steel of the blade extends the entire length of the handle and is secured with one or two mekugi bamboo pegs through the tsuka. Full-tang assembly is the traditional Japanese method and ensures that the blade, habaki collar, and handle components form a single rigid unit. This construction is a hallmark of properly crafted nihonto-style pieces and is an important quality indicator for collectors evaluating structural authenticity. A few models in the collection follow the shirasaya format, where the tang is housed inside a plain wooden grip without a traditional tsuba guard — a storage-style mounting historically used for blade preservation between fittings. Both styles are well-suited for display and collection purposes.
