Katana helps you organize your knife collection and explore the people, places, and craft behind Japanese and kitchen knives. Built for the knife collector, home cook, and chef, it brings knife collecting, private records, and source-backed Edge Index research together. MAKE YOUR COLLECTION YOUR OWN Record each knife's maker, steel, dimensions, purchase details, and personal notes. Add photographs and adjust their framing while preserving the originals. Organize the knives you own, your archive, and your wishlist. EXPLORE JAPANESE KNIVES WITH EDGE INDEX Discover makers, workshops, steels, knife types, techniques, and regions. Read complete maker profiles and regional articles with their supporting sources. Explore the regional map and save research to your private reading list. Public research stays separate from your personal knife records. Regional articles are included for offline reading and refreshed with app updates. ADD KNIVES YOUR WAY Enter a knife manually, import a supported retailer page, scan a receipt, or bring in a spreadsheet. Review the information before saving. Katana also supports scanning and claiming compatible digital knife passports. KEEP YOUR COLLECTION WITH YOU Sign in to the same Katana account on your devices to synchronize your collection and saved research. Clear status and recovery choices help you manage interrupted connections and changes made on more than one device.
