What should I look for in tanto fittings when collecting?
Updated Feb 2026
Fittings — collectively called koshirae — are often where the real artistry of a tanto is concentrated. The tsuba (guard) is the most visually prominent fitting, and motifs such as dragons, floral patterns, and geometric designs each carry distinct aesthetic and historical associations. Bronze and brass tsuba develop a warm patina over time, while alloy fittings maintain a more consistent finish with minimal maintenance. The habaki (blade collar) should fit snugly without play, as loose fitment indicates lower manufacturing precision. The menuki (handle ornaments) and kashira (pommel cap) should be cleanly cast with crisp detail rather than blurry, mass-produced profiles. Full-tang construction — where the steel extends fully into the handle — is a key indicator of quality assembly, and collectors should always confirm this detail before adding a piece to a serious display.
