Knife Steel Atlas

Knife Steel Atlas brings blade materials, knife identification, and your personal collection together in one place. EXPLORE AND COMPARE STEELS Browse popular steels such as CPM MagnaCut, CPM 3V, M390, and S35VN, along with specialty alloys and other blade materials. Explore ratings, typical hardness, composition, strengths, tradeoffs, care guidance, and detailed material stories. Compare materials side by side or use Steel Finder to find options suited to your priorities. BUILD YOUR KNIFE COLLECTION Save knives with original-resolution photos, blade steel, lock type, finishes, handle materials, colors, notes, cost, estimated value, and purchase details. Tap photos to view them full screen, pinch to zoom, pan, double-tap, and swipe between images. Browse supported makes, models, and variants, or add a knife manually. Edit your knife information in one place and see when you acquired each knife and how long you have owned it. RECORD SALES, TRADES, AND GIFTS Mark a knife as sold, traded, or gifted with straightforward forms. Record a sale price, choose a buyer, describe what you received in a trade, or keep a note about a gift. Find past knives in Previously Owned Knives and keep their history when a knife comes back into your collection. These tools record your own transactions; the app does not buy or sell knives. UNDERSTAND YOUR COLLECTION Explore your makers, steels, steel variety, Atlas coverage, and collection value. Ownership insights help you understand recorded sales and trades with clear gain or loss information based on the values you enter. SCAN BARCODES AND BOX LABELS Scan supported UPC and EAN barcodes to search the included knife catalog. The Box Label Scanner uses on-device text recognition to read packaging details such as model names and SKUs. Review or correct the recognized text, then choose from catalog matches. EXPLORE THE KNIFE CATALOG Browse thousands of knife models, variants, and configurations. If a knife is missing, add it manually and use Suggest a Knife to help expand catalog coverage.
