A blue katana trades tradition for personality: heat-tinted or coated blade, blue tsuka-ito wrap, and a deep-blue lacquered saya. It is the most popular colour choice after black — visible in a display case, distinctive in photos, and still a fully functional hand-forged sword underneath the finish. Same steels as the rest of the catalogue (T10, manganese, damascus), same full-tang build; the blue is the statement. Filter this collection by steel and blade finish to find the exact shade — from subtle heat-blue edges to full deep-blue blades.
